SN74HC193AN

Counter Dividers Overview

The SN74HC193AN is a 4-bit synchronous up/down binary counter from Texas Instruments, part of the HC logic family. It features dual clock inputs for independent up and down counting operations, along with an asynchronous clear input. The device operates on a supply voltage range of 2 V to 6 V and supports industrial temperature grades. It is housed in a 16-pin DIP package, designed for through-hole mounting on printed circuit boards.

Counter Dividers Feature Summary

• Synchronous 4-bit up/down binary counting capability
• Dual clock inputs for independent control of count direction
• Asynchronous clear function for immediate reset

Counter Dividers Applications

• Industrial digital counting systems
• Frequency division circuits
• Timing sequence generation

Counter Dividers Procurement Notes

Verify the specific suffix 'AN' confirms the industrial temperature grade and 16-pin DIP package configuration. Ensure compatibility with through-hole assembly processes. Confirm RoHS compliance status as per the latest manufacturer documentation before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when synchronous operation with separate up/down clocks is required in industrial environments. The HC series offers standard CMOS performance suitable for general-purpose digital logic applications requiring reliable binary counting within the specified voltage and temperature ranges.

Counter Dividers Part Context

This component belongs to the SN54HC193/SN74HC193 family of 4-bit synchronous reversible counters. The 'SN74HC193AN' variant specifically denotes the commercial/industrial grade version in a plastic DIP package, distinguishing it from SOIC or TSSOP surface-mount alternatives within the same functional family.

Counter Dividers FAQ

What is the primary difference between the SN74HC193 and SN74HC191?

The SN74HC193 uses separate clock inputs for up and down counting, whereas the SN74HC191 uses a single clock input with a separate up/down control pin.

Does the SN74HC193AN support parallel load functionality?

No, the SN74HC193 does not have a parallel load feature; it only supports serial counting via its dedicated up and down clock inputs.
