74AHC164D14

Shift Registers Overview

The Diodes Incorporated 74AHC164D14 is an 8-bit parallel-out serial shift register housed in a PDIP-14 package. It operates on a supply voltage range of 2.0V to 5.5V and features Schmitt trigger inputs for noise immunity. The device includes two logically ANDed serial data inputs (DSA, DSB) and an asynchronous Master Reset (MR) pin that forces all outputs low. Data shifts on the positive edge of the clock pulse, with propagation delays typically ranging from 4.5ns to 9.3ns depending on load capacitance and voltage.

Shift Registers Feature Summary

• Provides eight independent data outputs from a single serial input stream via edge-triggered shifting.
• Incorporates Schmitt trigger action at all inputs to ensure clean signal transitions.
• Features an asynchronous Master Reset function that overrides clock and data signals.

Shift Registers Applications

• General purpose logic circuits
• Computer peripherals and hard drives
• Networking equipment and PCs

Shift Registers Procurement Notes

Verify the specific ordering suffix matches the required package type. The D14 suffix indicates a PDIP-14 tube packaging format, distinct from the S14 or T14 tape and reel options. Confirm RoHS compliance and lead-free status requirements against project specifications before finalizing procurement orders.

Shift Registers Selection Notes

Select this component when an 8-bit serial-to-parallel conversion is required within standard CMOS logic families. Ensure the operating voltage aligns with the 2.0V to 5.5V specification. Consider the PDIP-14 package only if through-hole mounting is necessary, as other variants offer surface mount alternatives.

Shift Registers Part Context

This part belongs to the 74AHC series of high-speed CMOS logic devices manufactured by Diodes Incorporated. The 74AHC164 specifically implements an 8-bit shift register architecture. It is designed for general-purpose digital applications requiring reliable data storage and transfer capabilities within standard logic voltage ranges.

Shift Registers Replacement Considerations

Compatible replacements include the 74AHC164S14-13 (SO-14) and 74AHC164T14-13 (TSSOP-14). These variants share identical electrical characteristics and pinouts but differ in physical package dimensions and mounting style. Verify footprint compatibility before substitution.
