74AHC164T14-13

Overview

The 74AHC164T14-13 is an 8-bit parallel-out serial shift register manufactured by Diodes Incorporated. It operates on a supply voltage range of 2.0V to 5.5V and features edge-triggered data shifting with asynchronous master reset functionality. The device utilizes Schmitt trigger inputs for noise immunity and provides push-pull outputs capable of sourcing or sinking 8mA at VCC = 4.5V. It is housed in a TSSOP-14 package and complies with RoHS standards.

Feature Summary

• Edge-triggered serial-to-parallel conversion with dual logically ANDed serial data inputs
• Asynchronous master reset that forces all outputs low independent of clock signals
• Schmitt trigger action at all inputs to enhance noise rejection
• ESD protection exceeding JESD 22 specifications across multiple testing models

Applications

• General purpose logic circuits
• PCs, networking equipment, notebooks, and netbooks
• Computer peripherals including hard drives and CD/DVD ROMs
• Televisions, DVDs, DVRs, and set-top boxes

Procurement Notes

Verify the specific TSSOP-14 packaging configuration matches design requirements. Confirm RoHS compliance status aligns with environmental regulations. Ensure input pins are tied to valid logic levels when unused to prevent floating states. Validate operating temperature ranges against system constraints.

Selection Notes

Select this component for applications requiring wide voltage operation from 2.0V to 5.5V. Consider the TSSOP-14 package for surface-mount assembly needs. Evaluate the 8mA output drive capability against load requirements. Check propagation delay specifications against maximum clock frequency demands.

Part Context

This part belongs to the 74AHC logic family, designed for high-speed CMOS operations. It serves as a standard 8-bit shift register within Diodes Incorporated's portfolio. The T14 suffix specifically denotes the TSSOP-14 surface mount package variant.

Replacement Considerations

Cross-reference with other 74AHC164 variants from different manufacturers if pin compatibility is required. Verify electrical characteristics such as propagation delay and output current capabilities match original design specifications.
