74VHC595FT

Shift Registers Overview

The Toshiba 74VHC595FT is an advanced high-speed 8-bit shift register/latch fabricated with silicon gate C2MOS technology. It features a static shift register feeding an 8-bit storage register, with independent SCK and RCK inputs allowing stable parallel outputs during shifting. The device provides 3-state outputs for direct bus connection and includes input protection circuits supporting 0 to 5.5 V regardless of supply voltage. It operates within a wide voltage range of 2.0 V to 5.5 V and supports temperatures from -40°C to 125°C. Packaged in TSSOP-16B.

Shift Registers Feature Summary

• High-speed operation achieving frequencies up to 185 MHz at 5.0 V supply.
• Low power dissipation with quiescent current as low as 4.0 µA maximum.
• High noise immunity with balanced propagation delays and low output noise.
• Power-down protection provided on all inputs to prevent destruction from mismatched voltages.

Shift Registers Applications

• Serial-to-parallel data conversion systems
• Data receivers requiring 3-state bus interfacing
• Interfacing between 5 V and 3 V logic systems
• Battery backup systems utilizing two-supply configurations

Shift Registers Procurement Notes

Verify AEC-Q100 compliance requirements directly with Toshiba sales representatives if automotive reliability standards are mandatory for the application. Confirm that the TSSOP-16B package dimensions match the target PCB footprint. Ensure design accounts for derating factors above 85°C to maintain safe power dissipation levels within the specified operating temperature range.

Shift Registers Selection Notes

Select this component when high-speed shifting and latching are required alongside low power consumption. The 3-state outputs make it suitable for multiplexed bus architectures. Verify that the input voltage tolerance covers the system's maximum signal levels without external level shifting. Consider the wide operating temperature range for harsh environmental deployments.

Shift Registers Part Context

This device belongs to the 74VHC series of CMOS digital integrated circuits. It is pin and function compatible with other 74 series types such as 74AC, 74HC, 74AHC, and 74LV 595 variants. The 74VHC series offers performance similar to Bipolar Schottky TTL while maintaining CMOS low power characteristics, making it a drop-in replacement for legacy designs requiring higher speed.

Shift Registers Replacement Considerations

Pin-compatible alternatives include TC74VHC595F and TC74VHC595FK from Toshiba Semiconductor. Other manufacturers offering equivalent 8-bit shift registers with 3-state outputs may require verification of electrical parameters and timing characteristics to ensure functional equivalence.
