MC74HC393ADTR2

Counter Dividers Overview

The MC74HC393ADTR2 is a dual 4-stage binary ripple counter manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 6.0 V and supports counting rates up to 50 MHz. The device features asynchronous reset inputs and negative edge-triggered flip-flops. Packaged in a 14-TSSOP surface-mount format, it contains two independent counters, each providing parallel outputs for all four stages.

Counter Dividers Feature Summary

• Dual independent 4-bit binary ripple counter architecture
• Negative edge-triggered operation with asynchronous reset capability
• High noise immunity characteristic of CMOS devices
• Outputs directly interface to CMOS, NMOS, and TTL logic families

Counter Dividers Applications

• Digital frequency division circuits
• Binary counting applications in digital systems
• Cascaded counter configurations for extended bit depth

Counter Dividers Procurement Notes

Verify the complete part number including suffixes such as TR2 or TR2G against official datasheets to ensure correct packaging and compliance status. Confirm RoHS and REACH compliance documentation availability for specific manufacturing sites. Cross-reference pinout compatibility with legacy LS393 designs if integrating into existing hardware architectures.

Counter Dividers Selection Notes

Select this component when a dual 4-bit synchronous or ripple counter is required in a compact surface-mount package. Ensure the operating voltage aligns with the 2V to 6V specification. Consider the 50 MHz maximum counting rate for high-speed timing requirements. Verify input compatibility with driving logic levels, noting that pull-up resistors may be needed for LSTTL interfacing.

Counter Dividers Part Context

This device belongs to the 74HC series of high-speed CMOS logic components. It serves as a functional equivalent to the LS393 in terms of pinout, facilitating drop-in replacements in legacy designs. The series is characterized by low power consumption and wide operating voltage ranges suitable for various digital logic applications.

Counter Dividers Replacement Considerations

The MC74HC393A is pin-compatible with the SN74LS393. Verify electrical characteristics differences between HC and LS families before substitution.
