74ACT11074DG4

Overview

The Texas Instruments 74ACT11074DG4 is a dual positive-edge-triggered D-type flip-flop from the 74ACT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs with CMOS outputs. The device provides non-inverting and inverting outputs, offering a propagation delay of 8.5 ns at 5 V. It supports high drive currents of 24 mA for both sourcing and sinking. Packaged in a 14-SOIC surface-mount format, it functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Dual positive-edge-triggered D-type flip-flops with independent clock and data inputs
• TTL-compatible input thresholds ensuring direct interface with standard logic families
• Complementary (non-inverting and inverting) outputs for flexible signal routing
• High current drive capability supporting direct load interfacing without external buffers

Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations in digital systems
• Timing delay elements and pulse synchronization stages
• General-purpose storage registers in microprocessor interfaces

Procurement Notes

Verify the specific suffix 'DG4' against official manufacturer documentation to confirm package dimensions and tape/reel specifications. Ensure compatibility with existing PCB footprints by cross-referencing the SOIC-14 pinout. Confirm RoHS compliance status through the latest datasheet revision notes before finalizing procurement orders.

Selection Notes

Select this component when dual isolated flip-flops are required within a single package to minimize board space. The ACT series offers faster switching speeds compared to standard AC variants while maintaining similar power consumption profiles. Verify that the system's operating voltage remains strictly within the 4.5 V to 5.5 V window to ensure timing parameters remain valid.

Part Context

This part belongs to the 74ACT11074 series, which contains two independent D-type flip-flops. It differs from the 74AC11074 primarily in input threshold characteristics, providing TTL compatibility rather than pure CMOS input requirements. The 'G4' suffix typically indicates lead-free and RoHS-compliant manufacturing processes within the Texas Instruments product line.

Replacement Considerations
