Part Number : 74HCT193
Function :Dual retriggerable monostable multivibrator with reset
Manufacturer : NXP Semiconductors.
Pinout : 
Description
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.
* Input levels:
- For 74HC193: CMOS level
- For 74HCT193: TTL level
* Synchronous reversible 4-bit binary counting
* Asynchronous parallel load
* Asynchronous reset
* Expandable without external logic
* Complies with JEDEC standard no. 7A
