74HCT374DB,118

Overview

The Nexperia 74HCT374DB,118 is an octal D-type flip-flop with positive-edge triggering and three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V. The device features a common clock input and eight data inputs corresponding to the flip-flops. Outputs are controlled by a separate output enable input. It is housed in a 20-SSOP package and supports surface-mount installation.

Feature Summary

• Octal D-type flip-flop architecture with positive-edge triggering
• Three-state non-inverting outputs for bus-oriented applications
• Common output enable input for high-impedance control

Applications

• Bus-oriented memory register implementations
• Parallel-to-serial data conversion circuits
• General-purpose digital logic storage elements

Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure ESD handling protocols are followed during assembly due to CMOS sensitivity.

Selection Notes

Select this component when an octal storage element with tri-state capability is required for 5V logic systems. Compare propagation delay and power dissipation characteristics against alternative HCT series devices. Verify that the SSOP package dimensions fit the target PCB footprint constraints.

Part Context

This part belongs to the 74HCT family of high-speed CMOS logic devices. It provides TTL-compatible input levels while maintaining CMOS output drive capabilities. The device is designed for general-purpose digital applications requiring reliable data latching and bus interfacing in standard 5V environments.

Replacement Considerations

Check for direct pin-compatible alternatives such as the 74HC374 or other manufacturers' 74HCT374 variants. Verify electrical parameter equivalence before substitution.
