Flip Flops datasheet and documents for SN74LS74ADG4

SN74LS74ADG4

Flip Flops Overview

The SN74LS74ADG4 is a dual positive-edge-triggered D-type flip-flop from Texas Instruments' 74LS series. It features independent preset and clear inputs, complemented by Q and Q outputs. The device operates within a supply voltage range of 4.75V to 5.25V and supports surface-mount installation in a 14-SOIC package with a 0.154-inch width. Key electrical characteristics include a propagation delay of 40ns at 5V with 15pF load, a maximum clock frequency of 33MHz, and output currents of -400µA (high) and 8mA (low).

Flip Flops Feature Summary

Dual positive-edge-triggered D-type flip-flops with independent asynchronous preset and clear controls.
Complementary Q and Q outputs for versatile logic state monitoring.
Surface-mount SOIC-14 packaging optimized for automated assembly processes.

Flip Flops Applications

Parallel data storage and register circuits.
Shift register configurations for serial-to-parallel conversion.
Frequency division and timing control logic.

Flip Flops Procurement Notes

Verify the specific 'DG4' suffix against official Texas Instruments documentation to confirm RoHS compliance and lead-free status. Ensure the ordering part number matches the exact package dimensions and pinout requirements for your PCB footprint. Cross-reference datasheet revisions to confirm current manufacturing status and availability constraints.

Flip Flops Selection Notes

Select this component when dual edge-triggered storage is required in a compact surface-mount format. Compare propagation delays and output drive capabilities against alternative LS-series devices if higher speed or different loading conditions are present. Confirm thermal management needs for the SOIC-14 package under expected operating temperatures.

Flip Flops Part Context

This component belongs to the standard 74LS TTL logic family, known for low power consumption relative to earlier standards while maintaining compatible switching speeds. The SN74LS74 variant specifically provides two isolated flip-flops, making it a fundamental building block for sequential logic design in digital systems requiring reliable state retention.
