Flip Flops datasheet and documents for SN74LS74ADR

SN74LS74ADR

Flip Flops Overview

The SN74LS74ADR is a dual D-type flip-flop from the Texas Instruments SN74LS series, housed in a 14-SOIC surface-mount package. It operates on a supply voltage of 4.75V to 5.25V with a maximum propagation delay of 40ns at 5V and 15pF load. The device features positive-edge triggering, complementary outputs, and independent preset and clear inputs. It supports a clock frequency up to 33 MHz and functions within an ambient temperature range of 0°C to 70°C.

Flip Flops Feature Summary

Dual positive-edge triggered D-type flip-flops with complementary outputs
Independent asynchronous preset and clear inputs for direct state control
Standard TTL logic levels compatible with LS family interfaces

Flip Flops Applications

Parallel-to-serial data conversion circuits
Digital timing and synchronization logic
State storage in sequential control systems

Flip Flops Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and tape-and-reel specifications. Ensure compatibility with existing board layouts regarding SOIC-14 footprint dimensions. Confirm RoHS compliance status matches current manufacturing standards before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when dual edge-triggered storage is required in space-constrained designs. The SOIC package offers a compact alternative to through-hole options while maintaining standard LS logic performance characteristics. Verify input voltage thresholds align with the driving circuit's output levels.

Flip Flops Part Context

This part belongs to the widely adopted SN74LS logic family, known for balanced speed and power consumption. The 'A' variant typically denotes improved switching characteristics over the base model. The 'DR' suffix indicates a specific reel-based packaging format suitable for automated surface-mount assembly processes.
