74ACT11074D

Overview

The Texas Instruments 74ACT11074D is a dual positive-edge-triggered D-type flip-flop in the ACT logic series. It features two independent circuits, each with one bit capacity, housed in a 14-SOIC surface-mount package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL-compatible inputs. Key electrical parameters include a maximum propagation delay of 8.5 ns at 5 V with 50 pF load, a clock frequency of 125 MHz, and output drive currents of ±24 mA. Static current consumption is 4 µA, with an input capacitance of 3.5 pF. It functions across a temperature range of -40°C to +85°C.

Feature Summary

• Dual positive-edge-triggered D-type flip-flops with set and reset functionality
• TTL-compatible CMOS inputs for direct interfacing with standard logic families
• High-speed operation with propagation delays as low as 8.5 ns
• Complementary (inverting/non-inverting) outputs providing push-pull drive capability

Applications

• Parallel-to-serial data conversion circuits
• Shift register construction and implementation
• Digital signal processing timing synchronization
• Memory address latching in embedded systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct package type and tape/reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference the component marking code with the latest production change notices to avoid counterfeit or obsolete variants. Ensure the supplier provides traceable documentation matching the SN74ACT11074D part number.

Selection Notes

Select this component when dual independent D-type storage elements are required in a compact surface-mount format. The ACT series offers superior speed compared to standard 74LS logic while maintaining pin compatibility. Consider the 14-pin SOIC footprint for PCB layout constraints. Verify that the 5V operating voltage aligns with the system power rails and that the 8.5 ns delay meets the timing budget of the target application.

Part Context

The 74ACT11074D belongs to Texas Instruments' advanced CMOS (ACT) logic family, designed for high-speed digital applications.
