描述 :
The 74HC193; 74HCT193 is a 4-bit synchronous binary up/down counter. Separate up/down clocks, CPU and CPD respectively, simplify operation. The outputs change state synchronously with the LOW-to-HIGH transition ofeither clock input.
1. Input levels:
– For 74HC193: CMOS level
– For 74HCT193: TTL level
2. Synchronous reversible 4-bit binary counting
3. Asynchronous parallel load
4. Asynchronous reset
5. Expandable without external logic
6. Complies with JEDEC standard no. 7A
