74VHC175M

Overview

The Fairchild Semiconductor 74VHC175M is an advanced high-speed CMOS octal D-type flip-flop with three-state outputs. It operates within a supply voltage range of 2V to 5.5V and features a maximum propagation delay of 9.3ns at 5V with 50pF load capacitance. The device supports a clock frequency up to 115 MHz, provides 8mA output drive current, and consumes only 4µA static current. Packaged in a 16-TSSOP surface-mount format, it functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Octal D-type flip-flop architecture with master reset functionality
• Three-state outputs for effective bus line driving
• High noise immunity with power-down protection on all inputs

Applications

• Parallel data storage applications
• Shift register configurations
• Bus-oriented memory registers

Procurement Notes

Verify the specific suffix (e.g., MTC vs M) against official datasheets to confirm package dimensions and pinout compatibility. Ensure the manufacturer designation aligns with current On Semiconductor product lines following corporate integration. Confirm RoHS compliance status directly from the component marking or latest documentation before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring parallel data retention with minimal power consumption. The low input capacitance of 4pF makes it suitable for high-frequency clocking scenarios up to 115MHz. Consider the 16-TSSOP package constraints for PCB layout space and thermal management requirements during the initial design phase.

Part Context

This part belongs to the 74VHC logic family, which combines the speed performance of equivalent Bipolar Schottky TTL with standard CMOS low-power dissipation characteristics. It serves as a direct functional replacement for older 74HC series devices while offering improved switching speeds and lower quiescent current draw in modern digital circuit designs.

Replacement Considerations

Consult official cross-reference guides for exact pin-compatible alternatives such as the 74VHC175MX variant. Verify that any substitute maintains identical electrical specifications and package footprint to ensure seamless integration without redesigning the host circuit board.
