SN74HC393APWR

Counter Dividers Overview

The SN74HC393APWR is a dual 4-bit binary counter from Texas Instruments' HC logic family. It integrates two independent counters within a single package, each featuring parallel outputs and dedicated clear (CLR) and clock (CLK) inputs. The device operates on a supply voltage range of 2 V to 6 V and supports asynchronous reset functionality. Designed for surface-mount applications, it utilizes a 14-TSSOP package. The component facilitates system timing signals by providing frequency division capabilities, allowing input counting frequencies to be divided by any sub-multiple up to 256.

Counter Dividers Feature Summary

• Integrates two independent 4-bit binary counters in a single package
• Provides parallel outputs for generating system timing signals
• Features asynchronous clear inputs for direct resetting of each counter

Counter Dividers Applications

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

Counter Dividers Procurement Notes

Verify the specific suffix 'A' against official Texas Instruments documentation, as standard datasheets typically list variants such as SN74HC393PW or SN74HC393PWR. Confirm RoHS compliance status and ensure the 14-TSSOP package dimensions match design requirements. Cross-reference with authorized distributors to validate current availability and authenticity.

Counter Dividers Selection Notes

Select this component when dual independent 4-bit counting is required in a compact surface-mount form factor. Ensure the operating voltage aligns with the 2 V to 6 V specification. Verify that the asynchronous reset feature meets the system's initialization needs. Consider the TSSOP package constraints for PCB layout and thermal management during selection.

Counter Dividers Part Context

This part belongs to the SN74HC393 series of dual 4-bit binary counters. It shares functional characteristics with other variants like SN74HC393N and SN74HC393DR, differing primarily in packaging and manufacturing revisions. The HC series indicates high-speed CMOS technology, offering compatibility with standard TTL loads while maintaining low power consumption typical of CMOS devices.

Counter Dividers Replacement Considerations

Direct substitutes include SN74HC393PWR and SN74HC393PW. Other manufacturers offer compatible parts such as Nexperia 74HC393BQ and onsemi MC74HC393ADTR2G. Verify pinout compatibility and electrical specifications before substitution.
