74AHCT164PW,118

Shift Registers Overview

The Nexperia 74AHCT164PW,118 is an 8-bit serial-in/parallel-out shift register in the AHCT logic family. It features two serial data inputs (DSA and DSB) and eight parallel outputs (Q0 to Q7). Data shifts on LOW-to-HIGH clock transitions, while a LOW master reset clears all outputs. The device operates at 4.5 V to 5.5 V with TTL input levels. It uses a TSSOP14 package (SOT402-1), supports -40 °C to +125 °C temperatures, and exhibits a typical propagation delay of 3.4 ns.

Shift Registers Feature Summary

• TTL-compatible input levels for direct interfacing with standard logic families
• Overvoltage tolerant inputs allowing operation in mixed voltage environments
• Schmitt-trigger action on all inputs to ensure noise immunity
• Active LOW master reset function to clear the register independently of other inputs

Shift Registers Applications

• Serial-to-parallel data conversion in digital systems
• Parallel output expansion for microcontroller I/O ports
• Data storage and buffering in communication interfaces

Shift Registers Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the AHCT designation aligns with system voltage requirements. Ensure environmental specifications meet operational temperature ranges. Validate RoHS compliance status against current regulatory standards before finalizing procurement orders.

Shift Registers Selection Notes

Select this component when TTL-level compatibility is required within a CMOS environment. The TSSOP14 package suits space-constrained surface-mount designs. Verify that the supply voltage range covers the system's nominal operating conditions. Consider the propagation delay characteristics for timing-sensitive applications.

Shift Registers Part Context

This part belongs to the 74AHCT164 series, which includes variants like the 74AHCT164D and 74AHCT164BQ. These share identical logical functionality but differ in physical packaging. The PW suffix specifically denotes the TSSOP14 thin shrink small outline package configuration used in this product.

Shift Registers Replacement Considerations

Direct substitutes include the 74AHCT164D and 74AHCT164BQ from Nexperia. Cross-manufacturer equivalents must match the AHCT logic family and TSSOP14 package dimensions.
