SN74HC163DBRE4

Counter Dividers Overview

The SN74HC163DBRE4 is a synchronous 4-bit binary counter from the Texas Instruments 74HC series, housed in a 16-pin SOIC package. It operates on a positive-edge triggered clock with simultaneous flip-flop activation. The device supports synchronous preset loading and synchronous master reset functions. It features an internal look-ahead carry for efficient serial cascading. Operating voltage ranges from 2 V to 6 V, with a functional temperature range of -40°C to +85°C.

Counter Dividers Feature Summary

• Synchronous operation ensures all flip-flops are clocked simultaneously on the positive-going edge of the clock signal.
• Includes a synchronous master reset that clears outputs only upon the next positive clock transition.
• Features an internal look-ahead carry output to simplify the serial cascading of multiple counters.
• Inputs include clamp diodes to allow interfacing with voltages exceeding VCC using current-limiting resistors.

Counter Dividers Applications

• Digital timing circuits requiring precise synchronous counting sequences
• Frequency division applications within digital logic systems
• Event counting modules in industrial control equipment
• Serial cascading configurations for extended bit-counting operations

Counter Dividers Procurement Notes

Verify the specific RE4 suffix against the manufacturer's official documentation to confirm compliance with environmental standards and material composition requirements. Ensure the selected distributor provides traceable supply chain data. Confirm that the SOIC-16 package dimensions match the target PCB footprint specifications before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when synchronous preset and reset capabilities are required for deterministic state management. The HC logic family offers CMOS-level input compatibility suitable for general-purpose digital designs. Consider the 2 V to 6 V operating range for flexibility in varying power supply environments. Verify that the 36 MHz maximum frequency meets the system clock requirements.

Counter Dividers Part Context

This part belongs to the SN74HC163 family of synchronous 4-bit binary counters. It shares core logical functionality with variants such as SN74HC163DR and SN74HC163PWR but differs in packaging and manufacturing revisions. The device is designed for high-speed digital applications requiring reliable synchronous data handling and low power consumption characteristics typical of CMOS technology.

Counter Dividers Replacement Considerations

SN74HC163DR is a verified substitute offering identical logical functionality in a standard SOIC-16 package without the RE4 suffix. SN74HC163PWR serves as an alternative in a TSSOP-16 package, requiring footprint verification. Cross-reference datasheets to ensure pinout compatibility and electrical parameter alignment before implementation.
