MC74HC393ADR2

Counter Dividers Overview

The MC74HC393ADR2 is a dual 4-bit binary ripple counter manufactured by onsemi. It operates within a supply voltage range of 2 V to 6 V and supports counting rates up to 50 MHz. The device features asynchronous reset functionality and negative edge-triggered flip-flops. It is housed in a 14-SOIC surface-mount package with an operating temperature range of -55°C to 125°C.

Counter Dividers Feature Summary

• Dual independent 4-bit binary ripple counters
• Asynchronous reset capability for both counters
• Negative edge-triggered clock inputs
• High noise immunity characteristic of CMOS devices

Counter Dividers Applications

• Digital frequency division circuits
• Binary counting applications
• Timing sequence generation systems
• Cascaded ÷256 counter configurations

Counter Dividers Procurement Notes

Verify the exact suffix against official documentation, as 'MC74HC393ADR2' may be a truncated identifier for 'MC74HC393ADR2G'. Confirm RoHS compliance status and specific packaging options such as tape and reel quantities directly with the manufacturer or authorized distributors to ensure component authenticity and specification alignment.

Counter Dividers Selection Notes

Select this component when a dual-channel binary counting solution is required within standard HC logic families. Ensure the design accommodates the 2 V to 6 V supply range and utilizes negative edge-triggered clocking. Verify that the 14-SOIC package dimensions fit the target PCB layout constraints and thermal requirements.

Counter Dividers Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices produced by onsemi. It serves as a functional equivalent to legacy LS393 designs but offers improved performance characteristics typical of modern silicon-gate CMOS technology. The device is designed for compatibility with standard CMOS outputs and LSTTL outputs when pull-up resistors are applied.
