CD74ACT374E

Overview

The CD74ACT374E is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the ACT logic series. It features eight non-inverting circuits with three-state outputs housed in a 20-pin PDIP package. The device operates within a supply voltage range of 1.5 V to 5.5 V and supports through-hole mounting. Key electrical parameters include a propagation delay of 14 ns, high-level output current of -24 mA, and low-level output current of 24 mA. It functions reliably across a temperature range of -55 °C to +125 °C.

Feature Summary

• Octal configuration providing eight independent D-type flip-flops for parallel data storage
• Three-state outputs enable direct connection to bus systems without additional buffering
• ACT series technology ensures TTL-compatible inputs while maintaining CMOS performance levels

Applications

• Parallel-to-serial data conversion circuits
• Bus-oriented memory register implementations
• High-speed digital signal processing data latching

Procurement Notes

Verify the specific suffix 'E' corresponds to the PDIP-20 through-hole package variant. Confirm that the ACT series designation aligns with the required 1.5V to 5.5V operating voltage window. Ensure the procurement source provides official datasheets confirming the 14 ns propagation delay specification. Cross-reference the manufacturer part number against authorized distributor catalogs to validate authenticity and traceability.

Selection Notes

Select this component when an octal storage element with tri-state capability is required for bus architectures. The ACT series offers faster switching speeds compared to standard AC variants. Verify that the 20-pin DIP form factor fits the target PCB layout constraints. Consider the wide operating temperature range if the application involves industrial or automotive environments requiring robust thermal stability.

Part Context

This component is part of the Texas Instruments 74ACT family, designed to bridge the speed gap between HC and AC logic families. It serves as a fundamental building block for sequential logic designs requiring multiple synchronized data storage elements. The device complements other ACT series buffers and gates in complex digital system architectures.
