Description :
The CD74HC192, CD74HC193, CD74HC192E and CD74HCT193 are asynchronously presettable BCD Decade and Binary Up/Down synchronous counters, respectively. Presetting the counter to the number on the preset data inputs (P0-P3) is accomplished by a LOW asynchronous parallel load input (PL)\. The counter is incremented on the low-to-high transition of the Clock-Up input (and a high level on the Clock-Down input) and decremented on the low to high transition of the Clock-Down input (and a high level on the Clock-up input). A high level on the MR input overrides any other input to clear the counter to its zero state.
Features
1. Synchronous Counting and Asynchronous Loading
2. Two Outputs for N-Bit Cascading
3. Look-Ahead Carry for High-Speed Counting
