74HC163PW-Q100J

Counter Dividers Overview

The Nexperia 74HC163PW-Q100J is a synchronous presettable 4-bit binary counter with an internal look-ahead carry, housed in a 16-lead TSSOP plastic thin shrink small outline package (SOT403-1). It operates on a positive-edge triggered clock and features synchronous counting, loading, and reset functions. The device complies with AEC-Q100 Grade 1 standards for automotive applications, supporting ambient temperatures from -40 °C to +125 °C. It utilizes CMOS input levels and includes clamp diodes on inputs to allow interfacing with voltages exceeding VCC via current limiting resistors.

Counter Dividers Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standard
• Synchronous master reset and parallel load capabilities
• Internal look-ahead carry simplifies serial cascading of counters
• Positive-edge triggered clocking for simultaneous flip-flop updates

Counter Dividers Applications

• Automotive electronic systems requiring robust logic components
• Modulo-N counter designs using minimal external NAND gates
• Serial cascaded multi-stage binary counting circuits
• Glitch-free output generation in synchronous digital systems

Counter Dividers Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm package type and temperature range specifications. Ensure that the design environment meets the required AEC-Q100 Grade 1 qualification criteria. Confirm compatibility with system voltage levels and interface requirements prior to integration into production assemblies.

Counter Dividers Selection Notes

Select this component when synchronous operation and glitch-free resets are critical for system stability. The internal look-ahead carry feature reduces external logic complexity compared to asynchronous alternatives. Verify that the application requires CMOS input levels rather than TTL levels, which would necessitate the 74HCT variant instead.

Counter Dividers Part Context

This part belongs to the Nexperia 74HC163-Q100 family of synchronous 4-bit binary counters. It shares functional characteristics with the 74HCT163-Q100 but differs in input voltage level compatibility. The PW suffix specifically denotes the TSSOP16 package configuration, distinguishing it from the SO16 package variant designated by the D suffix.

Counter Dividers Replacement Considerations

The 74HCT163PW-Q100J serves as a compatible alternative within the same family, offering identical functionality with TTL-compatible input levels. Designers must verify voltage level compatibility when substituting between HC and HCT variants.
