Dual 4-bit binary ripple counter

Rev. 1 — 19 June 2014

Product data sheet

1. General description

The 74HC393-Q100; 7474HCT393-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 V_CC

This product has been qualified to the Automotive Electronics Council (AEC) standard

Q100 (Grade 1) and is suitable for use in automotive applications.

2. Features and benefits
