74AC11074NSRE4

Overview

The SN74AC11074NSRE4 is a dual positive-edge-triggered D-type flip-flop from the Texas Instruments AC logic family. It features independent clear and preset inputs for each flip-flop. The device operates within a supply voltage range of 3 V to 5.5 V. It utilizes a 14-pin SOIC surface-mount package. Key electrical specifications include a propagation delay of 10.5 ns, high-level output current of -24 mA, and low-level output current of 24 mA. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual configuration with two independent positive-edge-triggered D-type flip-flops
• Includes dedicated asynchronous clear and preset control inputs
• CMOS input and output structure compatible with standard logic levels

Applications

• Parallel data storage and buffering in digital systems
• Shift register construction for serial-to-parallel conversion
• State machine implementation in sequential logic circuits

Procurement Notes

Verify the specific suffix 'E4' indicates lead-free composition and RoHS compliance as per manufacturer documentation. Confirm the 'SR' designation corresponds to tape and reel packaging rather than tube packaging. Ensure the SOIC-14 footprint matches the target PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when dual edge-triggered storage with explicit set/reset capabilities is required. The AC series offers higher speed performance compared to HC variants while maintaining CMOS compatibility. Verify that the 3V to 5.5V operating range aligns with the system power supply rails and signal voltage levels.

Part Context

This part belongs to the SN74AC11074 family of dual D-type flip-flops. It serves as a functional equivalent to other industry-standard dual D-flip-flop components but is distinguished by its specific AC logic characteristics and TI manufacturing specifications. The device is designed for general-purpose digital logic applications requiring reliable state retention.

Replacement Considerations

Cross-reference with SN74AC11074N or SN74AC11074PW for alternative package options such as PDIP or TSSOP. Verify pinout compatibility and electrical parameters against SN74AC74 equivalents if preset/clear functionality differences are acceptable.
