SN74HC163IPWRQ1

Counter Dividers Overview

The SN74HC163IPWRQ1 is a synchronous, presettable 4-bit binary counter from the Texas Instruments HC series. It features an internal carry look-ahead circuit for high-speed cascading and operates on a positive-going clock edge. The device supports synchronous parallel loading and synchronous clearing of outputs. Qualified for automotive applications under AEC-Q100 standards, it functions within a supply voltage range of 2 V to 6 V and an operating temperature range of -40°C to +85°C. Packaged in a 16-pin TSSOP.

Counter Dividers Feature Summary

• Synchronous counting and loading with simultaneous flip-flop triggering
• Internal carry look-ahead circuitry for fast n-bit cascading
• Synchronous clear and load inputs independent of count enable states
• Automotive qualification compliant with AEC-Q100 reliability standards

Counter Dividers Applications

• High-speed synchronous binary counting circuits
• Cascaded multi-stage digital counters
• Programmable timing and frequency division modules
• Automotive electronic control unit logic interfaces

Counter Dividers Procurement Notes

Verify the complete part number including suffixes such as G4 against official ordering lists to ensure correct package type and tape-and-reel specifications. Confirm that the specific revision level matches design requirements. Check current product status to confirm active production availability before finalizing procurement plans.

Counter Dividers Selection Notes

Select this component when synchronous operation is required to eliminate output counting spikes associated with ripple counters. The internal look-ahead carry simplifies expansion beyond four bits without external gating logic. Ensure the application voltage remains within the specified 2 V to 6 V range for proper CMOS logic level compatibility.

Counter Dividers Part Context

This device belongs to the SN74HC163 family of synchronous 4-bit binary counters. The 'Q1' suffix indicates automotive qualification, while 'PWR' denotes the TSSOP surface-mount package. It serves as a core logic element for precise digital sequencing in environments requiring robust performance and standardized interface levels.

Counter Dividers Replacement Considerations

Catalog versions such as SN74HC163 are available but lack automotive qualification. Verify pinout compatibility and electrical characteristics when substituting non-qualified variants. Ensure any replacement maintains the synchronous clear and load functionality required by the existing circuit design.
