74AC11074NSRG4

Overview

The SN74AC11074NSRG4 is a dual D-type flip-flop from the Texas Instruments 74AC logic family, housed in a 14-pin SOIC package. It features positive-edge triggering with complementary outputs and includes asynchronous preset and clear inputs. The device operates within a supply voltage range of 3 V to 5.5 V, supporting propagation delays of 10.5 ns at 5 V. It provides high drive capability with output currents of ±24 mA and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Dual D-type flip-flops with positive-edge clock triggering
• Asynchronous active-low preset and clear control inputs
• Complementary Q and /Q outputs for versatile logic interfacing
• High current drive capability suitable for direct load driving

Applications

• Parallel-to-serial data conversion circuits
• Shift register construction for data storage and transfer
• Frequency division and timing signal generation
• General-purpose digital state storage applications

Procurement Notes

Verify that the ordering suffix 'G4' corresponds to the specific lead-free and RoHS-compliant variant required by your design specifications. Confirm the package type matches the PCB footprint requirements. Ensure the operating environment stays within the specified temperature limits. Cross-reference the manufacturer part number against official distribution channels to guarantee authenticity and traceability.

Selection Notes

Select this component when a dual D-type flip-flop with high-speed AC performance is needed in a surface-mount package. It is suitable for designs requiring strong output drive compared to standard HC series devices. Consider the 3 V to 5.5 V supply range compatibility with existing system voltages. Evaluate the 10.5 ns propagation delay against system timing constraints to ensure signal integrity.

Part Context

This part belongs to the Texas Instruments 74AC series, which offers faster switching speeds than the legacy 74LS family while maintaining similar pinouts. The 74AC11074 variant specifically integrates two independent flip-flops in a single package. The G4 suffix indicates compliance with environmental standards, distinguishing it from older non-compliant versions within the same functional family.

Replacement Considerations

The SN74AC11074N serves as a direct PDIP replacement offering identical electrical characteristics. For surface-mount applications, the SN74AC11074PWR or SN74AC11074PWRE4 are compatible alternatives with matching pinouts and performance parameters.
