74VHC164FT

Shift Registers Overview

The Toshiba Semiconductor and Storage 74VHC164FT is an advanced high-speed CMOS 8-bit serial-in parallel-out shift register fabricated with silicon gate C2MOS technology. It operates within a supply voltage range of 2.0 V to 5.5 V and supports a maximum clock frequency of 175 MHz at 5 V. The device features balanced propagation delays, low power dissipation, and input protection circuits allowing operation up to 5.5 V regardless of the supply voltage. It includes two serial data inputs for data enable functionality and an overriding clear input.

Shift Registers Feature Summary

• High-speed operation comparable to Bipolar Schottky TTL with CMOS low power dissipation
• Wide operating temperature range from -40°C to 125°C
• Power-down protection provided on all inputs
• Pin and function compatible with standard 74 series (AC/HC/AHC) 164 type logic

Shift Registers Applications

• Serial-to-parallel data conversion in digital systems
• Interface between 5 V and 3 V systems
• Battery backup system interfacing
• General-purpose shift register applications requiring high noise immunity

Shift Registers Procurement Notes

Verify AEC-Q100 compliance requirements directly with Toshiba sales representatives as specified in the datasheet notes. Confirm package availability and lead times through authorized distributors. Ensure design adheres to derating concepts for temperatures above 85°C to maintain reliability. Check RoHS and REACH status for environmental compliance before integration.

Shift Registers Selection Notes

Select this component when high-speed shifting is required alongside low power consumption. The wide voltage range supports mixed-voltage environments. Consider the TSSOP14B package for surface-mount applications. Verify that the maximum clock frequency meets system timing requirements under specific load and voltage conditions.

Shift Registers Part Context

This part belongs to the 74VHC family of advanced high-speed CMOS logic devices. It is functionally equivalent to other 8-bit serial-in parallel-out shift registers like the 74HC164 but offers improved speed and lower power characteristics. The 'FT' suffix indicates the TSSOP14B surface-mount package variant manufactured by Toshiba Semiconductor and Storage.

Shift Registers Replacement Considerations

Compatible replacements include other 74VHC164 variants from different manufacturers or pin-compatible parts from the 74HC164 or 74AHC164 families, provided voltage and speed requirements are met. Verify package compatibility and electrical characteristics against the original specification.
