SN74HC163DBR

Counter Dividers Overview

The SN74HC163DBR is a synchronous 4-bit binary counter manufactured by Texas Instruments in the HC logic series. It features positive-edge triggering and operates within a supply voltage range of 2 V to 6 V. The device is housed in a 16-pin SSOP package and supports surface-mount installation. It functions as an asynchronous reset counter with a maximum operating frequency of 36 MHz at 5 V, suitable for digital counting applications across industrial temperature ranges.

Counter Dividers Feature Summary

• Synchronous four-bit binary counting architecture with positive-edge clock triggering
• Asynchronous master reset input for immediate zeroing of count registers
• Three-state outputs enabling direct bus line interfacing without external buffers
• High-speed operation capability up to 36 MHz under standard supply conditions

Counter Dividers Applications

• Digital frequency division circuits requiring precise synchronous timing
• Event counting systems in industrial control panels
• Address decoding logic in microprocessor-based embedded designs
• Timing sequence generation for automated manufacturing equipment

Counter Dividers Procurement Notes

Verify the specific suffix 'DBR' confirms the SSOP-16 package and reel packaging format. Confirm RoHS compliance status matches current regulatory requirements. Ensure the supplier provides valid traceability documentation for the Texas Instruments manufacturer origin. Validate that the component lot date code aligns with project lifecycle needs to avoid obsolescence risks during production runs.

Counter Dividers Selection Notes

Select this component when synchronous counting behavior is required rather than ripple propagation delays found in asynchronous counters. The HC series offers broader voltage compatibility compared to HCT variants, supporting 2V to 6V operation. Consider the SSOP package constraints regarding thermal dissipation and PCB space availability. Verify that the 36 MHz speed rating meets the system clock requirements for the intended application frequency.

Counter Dividers Part Context

This part belongs to the Texas Instruments SN74HC163 family of synchronous 4-bit binary counters. It shares functional similarities with the SN74HC161 but differs in reset mechanism specifics. The DBR suffix denotes the specific tape-and-reel packaging configuration for automated assembly processes. It complements other HC series logic gates for complete digital system implementation.

Counter Dividers Replacement Considerations

SN74HC163DR serves as a pin-compatible alternative offering identical logical functionality in a SOIC-16 package. SN74HC161PWR provides similar counting capabilities but utilizes an active-low reset mechanism instead of high-level activation. Verify pinout compatibility and electrical characteristics before substituting these cross-reference parts.
