SN74HCT74PWT

Flip Flops Overview

The SN74HCT74PWT is a dual positive-edge-triggered D-type flip-flop from the Texas Instruments SN74HCT series. It operates within a supply voltage range of 4.5 V to 5.5 V and features low static power consumption with a maximum quiescent current of 2 µA. The device utilizes a 14-pin Thin Shrink Small Outline Package (TSSOP) for surface-mount assembly. It supports a maximum clock frequency of 36 MHz at 5.5 V and includes independent preset and clear inputs for direct control of output states.

Flip Flops Feature Summary

• Dual positive-edge-triggered D-type flip-flops with independent preset and clear controls

Flip Flops Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and specific tape-and-reel packaging quantities prior to ordering. Ensure compatibility with existing PCB footprint dimensions and soldering thermal profiles during integration planning.

Flip Flops Selection Notes

Select this component when TTL-compatible input thresholds are required alongside CMOS output drive capabilities. The HCT series ensures noise immunity improvements over standard HC variants. Verify that the operating temperature range meets system environmental requirements before finalizing the design specification.

Flip Flops Part Context

This device belongs to the widely adopted SN74HCT logic family, designed to bridge the gap between older TTL standards and modern CMOS technologies. The HCT designation indicates high-speed CMOS technology with TTL-compatible input levels, ensuring broad interoperability across mixed-logic system architectures.

Flip Flops Replacement Considerations

SN74HCT74PW: Same function with tube packaging instead of reel. SN74HCT74PWR: Same function with standard TSSOP-14 reel packaging.
