74HC193 Overview
74HC193; 74HCT193 Presettable synchronous 4-bit binary up/down counter Rev. 5 — 29 January 2016 Product data sheet 1. General 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 of either clock input. If the CPU clock is pulsed while CPD is held HIGH, the device will count up. If the CPD...
