74HCT393D

The 74HCT393D is a dual 4-stage binary ripple counter manufactured by NXP Semiconductors. Each counter within the device features a clock input (nCP) and an overriding asynchronous master reset input (nMR), along with four buffered parallel outputs (nQ0 to nQ3). The counter increments 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, irrespective of the clock input's state.

This component offers flexibility with input levels, supporting either CMOS or TTL logic, making it suitable for a wide range of digital systems. It complies with JEDEC standard no. 7A and provides significant ESD protection, exceeding 2000 V for HBM and 200 V for MM.

The 74HCT393D is available in multiple package types including SO14, SSOP14, TSSOP14, and DHVQFN14, all rated for an operating temperature range of -40 °C to +125 °C. Its design allows for division by any binary module up to 2^8 within a single package, and it includes two master resets for individual control of each 4-bit counter.
