Description
The 74HC161 is a synchronous presettable binary counter with an internal look-head carry.
Synchronous operation is provided by having all flip-flops clocked simultaneously on the positivegoing edge of the clock (CP).
The outputs (Q0 to Q3) of the counters may be preset HIGH or LOW.
Features
- Wide supply voltage range from 2.0 V to 6.0 V.
- CMOS low power dissipation.
- High noise immunity.
- Latch-up performance exceeds 100 mA per JESD 78 Class II Level B.
- Complies with JEDEC standards:.
- JESD8C (2.7 V to 3.6 V).
- JESD7A (2.0 V to 6.0 V).
- CMOS input levels.
- Synchronous counting and loading.
- 2 count enable inputs for n-bit cascading.
- Asynchronous reset.
- Positive-edge triggered clock.
