SN74HCT374N

Flip Flops Overview

The SN74HCT374N is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments. It features eight positive-edge triggered D-type flip-flops with three-state outputs in a 20-pin PDIP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input levels. It exhibits a maximum propagation delay of 41 ns at 5.5 V with 150 pF load, and offers symmetric output drive currents of 6 mA. The component functions across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration containing eight independent positive-edge triggered D-type flip-flops
• Three-state outputs enable direct connection to bus-oriented systems without additional buffering
• TTL-compatible inputs allow seamless integration with standard logic families
• Non-inverting polarity ensures data output matches input state upon clocking

Flip Flops Applications

• Buffer registers for temporary data storage
• I/O port implementations in interface circuits
• Bidirectional bus drivers for signal routing
• Working registers in digital processing units

Flip Flops Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm package type and tape/reel specifications. Ensure the ordering part number matches the required industrial temperature range and electrical characteristics. Cross-reference the datasheet revision date to validate current performance parameters before finalizing procurement decisions.

Flip Flops Selection Notes

Select this component when TTL-compatible inputs are required alongside high-speed tri-state outputs. The HCT series bridges CMOS density with TTL noise margins. Consider the 20-PDIP package for through-hole prototyping or legacy board designs requiring robust mechanical mounting compared to surface-mount alternatives.

Flip Flops Part Context

Flip Flops FAQ

What is the input logic level compatibility?

The SN74HCT374N features TTL-compatible inputs, allowing it to interface directly with standard TTL logic sources.

How does the output enable function work?

The Output Enable (OE) input controls the three-state condition, placing all eight outputs into a high-impedance state when activated.
