SN74S74D

Flip Flops Overview

The SN74S74D is a dual D-type positive-edge-triggered flip-flop manufactured by Texas Instruments in the S-series logic family. It features active-high preset and clear inputs for direct control of output states. The device operates within a supply voltage range of 4.5V to 5.25V and supports an operating temperature range of 0°C to +70°C. Packaged in a 14-pin SOIC (D) format, it provides push-pull outputs with a low-level output current capability of 8mA and a high-level output current of -4mA. Propagation delay is specified at 10.5ns.

Flip Flops Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure the component meets the required industrial temperature range and voltage parameters for your application. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and availability status prior to procurement.

Flip Flops Selection Notes

Select this component when dual independent D-type flip-flops are required in a standard TTL-compatible logic family. Consider the 14-pin SOIC package constraints and the specific propagation delay characteristics. Verify that the input/output electrical specifications align with the driving and loading requirements of the surrounding circuitry within the 5V logic environment.

Flip Flops Part Context

This component belongs to the Texas Instruments SN74S series, which represents Schottky-clamped logic designed for high-speed operation. The S-series offers improved speed compared to standard LS logic while maintaining compatible pinouts and electrical characteristics. This specific variant integrates two flip-flops into a single package for space-efficient digital design.

Flip Flops Replacement Considerations

Compatible substitutes include other SN74S74 variants from Texas Instruments or equivalent dual D-type flip-flops from other manufacturers offering identical pinouts and logical functions. Verify voltage levels and package dimensions before substitution.
