CD74HC193 counters equivalent, presettable synchronous 4-bit up/down counters.
* Synchronous Counting and Asynchronous Loading
* Two Outputs for N-Bit Cascading
* Look-Ahead Carry for High-Speed Counting
* Fanout (Over Temperature Ra.
The ’HC192, ’HC193 and ’HCT193 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 loa.
