SN74HC393APW

Counter Dividers Overview

The SN74HC393APW is a dual 4-bit binary counter from the Texas Instruments HC logic family, housed in a 14-TSSOP package. It operates on a supply voltage of 2 V to 6 V and supports an asynchronous up-counting sequence with negative-edge triggering. The device features independent clear inputs for each counter section and provides parallel outputs. It functions within a temperature range of -40°C to +85°C.

Counter Dividers Feature Summary

• Contains two independent 4-bit binary counters within a single integrated circuit
• Provides direct asynchronous clear functionality for immediate reset of count states
• Supports system timing signals through parallel output access at any bit position

Counter Dividers Applications

• Digital frequency division circuits
• System timing signal generation
• Binary counting applications requiring independent control sections

Counter Dividers Procurement Notes

Verify the specific suffix 'A' against official manufacturer documentation to confirm if it denotes a specific tape-and-reel variant or packaging configuration distinct from standard versions. Ensure the component matches the 14-TSSOP physical outline and HC logic electrical specifications before integration into designs.

Counter Dividers Selection Notes

Select this component when a design requires two separate 4-bit counters in a compact surface-mount footprint. It is suitable for low-voltage digital systems operating between 2 V and 6 V. Consider the asynchronous nature of the clear function and the negative-edge clock trigger when designing the control logic interface.

Counter Dividers Part Context

This part belongs to the SN74HC393 series of dual 4-bit binary counters. It shares core logical functionality with other variants such as SN74HC393DR and SN74HC393PW, differing primarily in the manufacturing lot or specific packaging format indicated by the suffix. It is designed for general-purpose digital counting tasks.

Counter Dividers Replacement Considerations

Direct substitutes include SN74HC393PWR and SN74HC393PW. Verify pinout compatibility and electrical characteristics against the datasheet before substitution.
