SN74HC163D

Counter Dividers Overview

The SN74HC163D is a synchronous 4-bit binary counter from the Texas Instruments SN74HC163 series. It operates within a supply voltage range of 2 V to 6 V and supports counting frequencies up to 36 MHz. The device features synchronous preset and synchronous clear functions, triggered by positive edges. It is housed in a 16-SOIC surface-mount package and is rated for an operating temperature range of -40°C to +85°C.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting with positive-edge triggering
• Independent synchronous preset and synchronous clear inputs
• High-speed operation supporting clock rates up to 36 MHz
• Wide power supply compatibility ranging from 2 V to 6 V

Counter Dividers Applications

• Digital timing and sequencing circuits
• Frequency division applications
• Event counting systems
• Control logic in embedded microcontroller interfaces

Counter Dividers Procurement Notes

Verify the specific suffix 'D' corresponds to the SOIC-16 package variant when sourcing. Confirm RoHS compliance status as indicated in official datasheets. Ensure the supplier provides genuine Texas Instruments components to guarantee electrical performance matches the published specifications for the HC logic family.

Counter Dividers Selection Notes

Select this component for designs requiring synchronous control over count and reset operations rather than asynchronous methods. It is suitable for low-voltage digital systems operating between 2 V and 6 V. Consider the 36 MHz maximum frequency limit when designing high-speed clock distribution networks or precise timing sequences.

Counter Dividers Part Context

This part belongs to the SN74HC163 family of synchronous 4-bit binary counters. It shares functional similarities with the SN74HC161 but differs in its reset mechanism, offering synchronous clear instead of asynchronous. The 'D' suffix specifically denotes the 16-pin Small Outline Integrated Circuit (SOIC) package configuration.

Counter Dividers FAQ

Is the clear function asynchronous or synchronous?

The clear function is synchronous, meaning it occurs on the next active clock edge after the clear signal is asserted.

What is the maximum operating frequency?

The device supports a maximum counting frequency of 36 MHz under standard operating conditions.
