74HC393-Q100; 74HCT393-Q100 Dual 4-bit binary ripple counter Rev.
3 — 22 October 2021 Product data sheet 1.
General description The 74HC393-Q100; 74HCT393-Q100 is a dual 4-stage binary ripple counter.
Each counter features a clock input (nCP), an overriding asynchronous master reset input (nMR) and 4 buffered parallel outputs (nQ0 to nQ3).
The counter advances on the HIGH-to-LOW transition of nCP.
A HIGH on nMR clears the counter stages and forces the outputs LOW, independent of the state of nCP.
Inputs include clamp diodes.
This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
