TOSHIBA Synchronous Presettable 4-Bit Counter TC74HC160 Decade, Asynchronous Clear TC74HC161 Binary, Asynchronous Clear TC74HC162 Decade, Synchronous Clear TC74HC163 Binary, Synchronous Clear The TC74HC160A,161A, 162A and 163A are high speed CMOS SYNCHRONOUS PRESETTABLE COUNTERS fabri- cated with silicon gate CMOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The 74HC160A/162A are BCD decade counters and the TC74HC161A/163<A are 4 bit binary counters. The CLOCK input is active on the rising edge. Both LOAD and CLEAR inputs are active on low logic level. Presetting of all four ICs is synchronous to the rising edge of CLOCK. The clear function of the TG74HC162A/163A is synchro- nous to CLOCK, while the TC74HC160A/161A are cleared asynchronously. Two enable inputs (ENP and ENT) and CARRY OUTPUT are provided to enable easy cascading of counters, which facilitates easy implementation of n-bit counters without using external gates. All inputs are equipped with protection circuits against static discharge or transient excess voltage.
