SN74HC163IPWRG4Q1

Counter Dividers Overview

The SN74HC163IPWRG4Q1 is a 4-bit synchronous binary counter from the Texas Instruments SN74HC163-Q1 automotive-qualified series. It operates within a supply voltage range of 2 V to 6 V and supports clock frequencies up to 36 MHz at 6 V. The device features internal carry look-ahead for high-speed cascading, synchronous preset capability, and synchronous clear functions. Packaged in a 16-pin TSSOP (PW) with an operating temperature range of -40°C to +85°C, it provides low power consumption with a maximum ICC of 80 µA.

Counter Dividers Feature Summary

• Synchronous operation ensures all flip-flops are clocked simultaneously to eliminate output counting spikes.
• Internal carry look-ahead circuitry enables high-speed n-bit cascading without additional external gating.
• Fully programmable design allows synchronous presetting to any value between 0 and 15.
• Automotive qualification meets AEC-Q100 standards for reliability in demanding environments.

Counter Dividers Applications

• High-speed synchronous binary counting designs
• n-bit cascaded counter systems utilizing internal carry look-ahead
• Automotive electronic control units requiring qualified logic components

Counter Dividers Procurement Notes

Verify that the specific part number includes the 'Q1' suffix to confirm AEC-Q100 automotive qualification status. Ensure the ordering suffix matches the required tape and reel packaging configuration. Confirm the package type corresponds to the PW (TSSOP) variant. Validate that the component meets the specified -40°C to +85°C operating temperature range for your application environment.

Counter Dividers Selection Notes

Select this component when synchronous counting behavior is required to prevent ripple-clock glitches. The internal carry look-ahead makes it suitable for applications needing fast multi-stage expansion. Consider the 2 V to 6 V supply range for compatibility with various logic families. Verify that the 16-pin TSSOP package fits the available PCB footprint constraints.

Counter Dividers Part Context

This device belongs to the SN74HC163-Q1 family, which represents the automotive-grade version of the standard SN74HC163 counter. It shares functional characteristics with catalog parts but adheres to stricter automotive reliability standards. The 'IPWRG4' suffix indicates the specific industrial grade, tape and reel packaging, and lead finish options provided by Texas Instruments.

Counter Dividers Replacement Considerations

Catalog versions such as SN74HC163PWR or SN74HC163DR offer identical logical functionality but lack AEC-Q100 automotive qualification. Substituting these requires verifying if the automotive reliability requirements can be waived for the specific application context.
