CD74HC193 Overview
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 acplished 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 ClockDown input) and decremented on the low to high...
