74HC393N,652

The 74HC393N,652 is a dual 4-stage binary ripple counter manufactured by NXP Semiconductors. Each counter includes a clock input (nCP) and an overriding asynchronous master reset input (nMR), with four buffered parallel outputs (nQ0 to nQ3). The counter advances on the HIGH-to-LOW transition of the clock input. A HIGH signal on the master reset input clears the counter stages and forces the outputs LOW, regardless of the clock state.

This component features a wide supply voltage range from 2.0 V to 6.0 V and offers CMOS low power dissipation with high noise immunity. It complies with JEDEC standards JESD8C (2.7 V to 3.6 V) and JESD7A (2.0 V to 6.0 V). The input levels are CMOS for the 74HC393 variant and TTL for the 74HCT393 variant. ESD protection is provided, exceeding 2000 V for HBM and 1000 V for CDM.

The 74HC393N,652 is available in a 14-DIP package and is designed for through-hole mounting. It operates within a temperature range of -40°C to +125°C. The device contains two independent 4-bit binary counters, each with individual clocks and master resets, allowing for division by any binary module up to 2^8 within a single package.
