FEATURES * 74F573 is broadside pinout version of 74F373 * 74F574 is broadside pinout version of 74F374 * Inputs and Outputs on opposite side of package allow easy It is an 8-bit, edge triggered register coupled to eight 3-State output buffers. The two sections of the device are controlled independently by the clock (CP) and Output Enable (OE) control gates. interface to Microprocessors * Useful as an Input or Output port for Microprocessors * 3-State Outputs for Bus interfacing * Common Output Enable * 74F563 and 74F564 are inverting version of 74F573 and 74F574 The register is fully edge-triggered. The state of each D input, one setup time before the Low-to-High clock transition is transferred to the corresponding flip-flop's Q output. The 3-State output buffers are designed to drive heavily loaded 3-State buses, MOS memories, or MOS microprocessors. The active Low Output Enable (OE) controls all eight 3-State buffers independently of the latch operation. When OE is Low, the latched or transparent data appears at the outputs. When OE is High, the outputs are in high impedance "off" state, which means they will neither drive nor load the bus. respectively * 3-State Outputs glitch free during power-up and power-down * These are High-Speed replacements for N8TS805 and N8TS806 DESCRIPTION The 74F573 is an octal transparent latch coupled to eight 3-State output buffers. The two sections of the device are controlled independently by Enable (E) and Output Enable (OE) control gates. The 74F573 is functionally identical to the 74F373 but has a broadside pinout configuration to facilitate PC board layout and allow easy interface with microprocessors. The data on the D inputs is transferred to the latch outputs when the Enable (E) input is High. The latch remains transparent to the data input while E is High and stores the data that is present one setup time before the High-to-Low enable transition.

The active Low Output Enable (OE) controls all eight 3-State buffers independent to the latch operation. When OE is Low, the latched or transparent data appears at the outputs. When OE is High, the outputs are in high impedance "off" state, which means they will neither drive nor load the bus.

For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type. 2. All typical values are at VCC = 5V, Tamb = 25C. 3. Not more than one output should be shorted at a time. For testing IOS, the use of high-speed test apparatus and/or sample-and-hold techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any sequence of parameter tests, IOS tests should be performed last. 1989 Oct 16 6 Philips Semiconductors Product specification Latch/flip-flop 74F573/74F574 AC ELECTRICAL CHARACTERISTICS LIMITS SYMBOL TEST CONDITIONS PARAMETER Tamb= +25C VCC = +5V CL = 50pF, RL = 500 Tamb = 0C to +70C VCC = +5V 10% CL = 50pF, RL = 500 MIN TYP MAX MIN MAX UNIT tPLH tPHL Propagation delay Dn to Qn Waveform NO TAG 3.0 1.0 5.5 3.5 8.0 6.0 2.5 1.0 9.0 7.0 ns tPLH tPHL Propagation delay E to Qn Waveform NO TAG 4.5 3.0 8.5 5.0 11.5 7.0 4.0 2.5 12.5 8.0 ns tPZH tPZL Output Enable time to High or Low level Waveform NO TAG Waveform NO TAG 2.5 2.5 5.5 5.5 9.5 8.0 2.0 2.0 10.5 8.5 ns tPHZ tPLZ Output Disable time from High or Low level Waveform NO TAG Waveform NO TAG 1.0 1.0 3.0 2.5 6.0 5.5 1.0 1.0 6.5 5.5 ns fMAX Maximum Clock frequency Waveform NO TAG 160 180 tPLH tPHL Propagation delay CP to Qn Waveform NO TAG 3.5 3.5 5.0 5.0 7.5 7.5 3.0 3.0 8.0 8.0 ns tPZH tPZL Output Enable time to High or Low level Waveform NO TAG Waveform NO TAG 2.5 3.0 4.5 5.0 7.5 8.0 2.0 3.0 7.5 8.5 ns tPHZ tPLZ Output Disable time from High or Low level Waveform NO TAG Waveform NO TAG 1.0 1.0 3.0 2.5 5.5 5.5 1.0 1.0 6.0 6.0 ns 74F573 74F574 150 MHz AC SETUP REQUIREMENTS LIMITS SYMBOL Tamb= +25C VCC = +5V CL = 50pF, RL = 500 TEST CONDITIONS PARAMETER MIN ts(H) ts(L) Setup time, Dn to E th(H) th(L) Hold time, Dn to E tw(H) TYP MAX Tamb = 0C to +70C VCC = +5.0V 10% CL = 50pF, RL = 500 MIN UNIT MAX Waveform 4 0.0 1.5 0.0 2.0 ns Waveform 4 2.5 4.0 2.5 4.0 ns E pulse width, High Waveform NO TAG 3.0 3.5 ns ts(H) ts(L) Setup time, Dn to CP Waveform NO TAG 2.5 2.5 3.0 3.0 ns th(H) th(L) Hold time, Dn to CP Waveform NO TAG 0 0 0 0 ns tw(H) tw(L) CP Pulse width, High or Low Waveform NO TAG 3.0 3.5 3.0 4.0 ns 1989 Oct 16 74F573 74F574 7 Philips Semiconductors Product specification Latch/flip-flop 74F573/74F574 AC WAVEFORMS For all waveforms, VM = 1.5V The shaded areas indicate when the input is permitted to change for predictable output performance. 1/fMAX E, CP VM VM tW(H) Dn VM VM tW(L) tPHL VM tPLH tPHL tPLH Qn VM Qn VM VM VM SF01081 SF01082 Waveform 1.
