TC74HC192AP/AF TC74HC193AP/AF/AFN TC74HC192AP/AF SYNCHRONOUS UP/DOWN DECADE COUNTER TC74HC193AP/AF/AFN SYNCHRONOUS UP/DOWN_BINARY COUNTER The TC74HC192A/TC74HCI93A are high speed CMOS SYNCHRONOUS 4-BIT UP/DOWN COUNTER fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to 16 equivalent LSTTL while maintaining the CMOS low power dissipation. 1 They have a clear input (CLEAR), a load input (LOAD), load data inputs (A~D), two clock inputs P(DIP18-P-300A) (COUNT UP, COUNT DOWN), four count data outputs (Qa~Qp), and other outputs (CARRY, BORROW). 16 Qt 16 OF CLEAR is active high and forces Qa thru Qp outputs low independent of the other inputs. 1 1 CARRY and BORROW outputs are provided in order to make a cascade connection without external circuitry. F(SOP16-P300) FN(SOL16~P-180) All inputs are equipped with protection circuits against static discharge or transient excess voltage. PIN ASSIGNMENT FEATURES: .
