74AC374SC

Overview

The onsemi 74AC374SC is an octal D-type flip-flop with 3-state outputs, manufactured in a 20-SOIC package. It operates within a supply voltage range of 2V to 6V and supports a maximum clock frequency of 155 MHz. The device features a typical propagation delay of 9.5ns at 5V with 50pF load, providing high-speed performance. Output drive capability is rated at 24mA for both sourcing and sinking currents, while static current consumption is low at 8µA. It functions over an extended temperature range from -40°C to +85°C.

Feature Summary

• Buffered positive edge-triggered clock input ensures stable data capture timing.
• Three-state outputs facilitate direct connection to bus-oriented systems without external buffers.
• CMOS construction provides high noise immunity and low power consumption.

Applications

• Bus-oriented memory register implementations
• High-speed data storage circuits
• Parallel-to-serial data conversion modules

Procurement Notes

Verify the specific suffix 'SC' against the manufacturer's official datasheet to confirm the exact package dimensions and tape/reel specifications. Confirm RoHS compliance status as manufacturing processes may evolve. Check for obsolescence notices or PCN documents regarding material changes before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring wide voltage operation between 2V and 6V. It is suitable for applications needing 8-bit parallel data latching with tri-state control. Compare against the 74ACT374 variant if TTL-compatible input thresholds are strictly required instead of standard CMOS levels.

Part Context

This part belongs to the 74AC logic family, representing advanced CMOS technology. It serves as the non-inverting data latch counterpart to other devices like the 74AC373 transparent latch. The 20-SOIC package allows for surface-mount assembly in compact electronic designs requiring multiple flip-flops in a single integrated circuit.
