Part Number: 74HCT193
Function: Presettable synchronous 4-bit binary up/down counter
Package: DIP, SO, SSOP, TSSOP 16 Pin Type
Manufacturer: NXP Semiconductors.
Image and Pinouts:
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.
If the CPU clock is pulsed while CPD is held HIGH, the device will count up. If the CPD clock is pulsed while CPU is held HIGH, the device will count down. Only one clock input can be held HIGH at any time to guarantee predictable behavior.
Features and benefits :
1. Input levels:
(1) For 74HC193: CMOS 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
