74HC164T14-13

Shift Registers Overview

The 74HC164T14-13 is an 8-bit parallel-out serial shift register manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.0V to 6.0V and features push-pull outputs capable of sinking or sourcing 4mA at VCC = 4.5V. The device utilizes Schmitt trigger inputs for noise immunity and includes ESD protection exceeding JESD 22 standards. It is housed in a TSSOP-14 package and supplied in tape and reel packaging with a quantity of 2,500 units.

Shift Registers Feature Summary

• Serial data input pins DSA and DSB are logically ANDed, allowing either pin to function as an active HIGH enable when the other serves as the data input.
• Asynchronous Master Reset (MR) pin forces all outputs to LOW regardless of clock or data states, requiring recovery time before subsequent clock edges.
• Data shifts into Q0 on each positive edge transition of the Clock Pulse (CP), transferring existing stage data to the next sequential output.

Shift Registers Applications

• General purpose logic circuits
• PCs, networking equipment, notebooks, and netbooks
• Computer peripherals including hard drives and CD/DVD ROM drives
• TV, DVD, DVR, and set-top box systems

Shift Registers Procurement Notes

Verify the specific ordering suffix matches the required package type, as the -13 suffix indicates Tape & Reel packaging. Confirm that the TSSOP-14 form factor aligns with the target PCB footprint. Ensure the application environment remains within the specified operating temperature range of -40°C to +125°C. Check for RoHS compliance requirements if applicable to the final assembly standards.

Shift Registers Selection Notes

Select this component when an 8-bit serial-to-parallel conversion is required with CMOS compatibility. The wide supply voltage range supports various logic levels from 2.0V to 6.0V. Consider the TSSOP-14 package for surface-mount applications requiring compact board space. Verify that the input current and power dissipation characteristics meet the system's thermal and electrical constraints.

Shift Registers Part Context

This part belongs to the 74HC164 family of 8-bit serial-in parallel-out shift registers. It is compatible with low-power Schottky TTL (LSTTL) logic levels. The device follows JEDEC standard no. 7A and offers multiple package options including SO-14, TSSOP-14, and PDIP-14. It is designed for general-purpose digital logic applications requiring reliable data shifting capabilities.

Shift Registers Replacement Considerations

Cross-reference with other manufacturers' 74HC164 equivalents ensuring identical pinout and electrical specifications. Verify package compatibility if substituting with SO-14 or PDIP-14 variants. Confirm that the replacement device meets the same ESD protection and operating voltage requirements.
