SN74ACT74DR

Flip Flops Overview

The SN74ACT74DR is a dual D-type flip-flop from the Texas Instruments SN74ACT series, housed in a 14-pin SOIC package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of -40°C to +85°C. The device features independent data (D) inputs, clock (CP) inputs, and complementary outputs (Q and Q-bar). Each flip-flop includes dedicated preset (PRE) and clear (CLR) inputs that function asynchronously. The logic type is CMOS, with TTL-compatible input thresholds.

Flip Flops Feature Summary

• Dual configuration containing two independent positive-edge-triggered D-type flip-flops within a single integrated circuit.
• Asynchronous control capabilities provided by active-low preset and clear inputs for immediate state initialization or reset.
• TTL-compatible input logic levels ensure direct interfacing with standard digital logic sources without additional level shifting.

Flip Flops Applications

• Parallel-to-serial and serial-to-parallel data conversion circuits
• Digital timing and delay line implementations
• Shift register stages in data processing systems

Flip Flops Procurement Notes

Verify the specific suffix 'DR' confirms the tape-and-reel packaging format required for automated surface-mount assembly processes. Confirm RoHS compliance status through the official manufacturer datasheet prior to final procurement decisions.

Flip Flops Selection Notes

Select this component when a compact dual flip-flop solution with asynchronous control is required. Ensure the design accommodates the 4.5V to 5.5V supply voltage constraint and verify that the SOIC-14 footprint aligns with the target PCB layout constraints.

Flip Flops Part Context

This part belongs to the SN74ACT family, which utilizes Advanced CMOS technology to deliver high-speed performance comparable to LS-TTL while maintaining low power consumption. The ACT series is designed for general-purpose digital applications requiring reliable operation across industrial temperature ranges.

Flip Flops Replacement Considerations

Check for SN74ACT74N for DIP packaging or SN74ACT74PW for TSSOP alternatives if pinout compatibility is maintained. Verify functional equivalence for any cross-manufacturer substitutes.
