SN74HC393NSR

Counter Dividers Overview

The SN74HC393NSR is a dual 4-bit binary counter from the Texas Instruments HC logic family, housed in a 14-pin SOP package. It operates on a supply voltage of 2V to 6V and supports an operating temperature range of -40°C to +85°C. The device integrates two independent counters with individual clock inputs and direct clear functions. It features parallel outputs for system timing signals and can drive up to 10 LSTTL loads.

Counter Dividers Feature Summary

• Dual 4-bit binary counters with individual clocks
• Direct clear for each 4-bit counter
• Parallel outputs from each counter stage

Counter Dividers Applications

• System timing signal generation
• Frequency division applications
• Digital counting circuits

Counter Dividers Procurement Notes

Verify the specific NS (SOP) package designation when ordering. Confirm RoHS compliance and lead finish details via the latest TI Package Option Addendum. Ensure design compatibility with the specified 2V to 6V operating voltage range and -40°C to +85°C temperature limits.

Counter Dividers Selection Notes

Select this component for designs requiring two independent 4-bit counters in a single package. It is suitable for applications needing direct clear functionality and parallel output access. Verify that the SOP package size fits the board layout constraints compared to other available packages like SOIC or TSSOP.

Counter Dividers Part Context

This part belongs to the SNx4HC393 series of dual 4-bit binary counters. It is designed to improve system densities by reducing counter package count. The device contains eight flip-flops and additional gating to implement two individual 4-bit counters within a single integrated circuit.
