74ACT11074NSR

Overview

The Texas Instruments 74ACT11074NSR is a dual positive-edge-triggered D-type flip-flop housed in a 14-pin SOP package. It features TTL-compatible inputs and CMOS outputs with both clear and preset functions. The device operates within a supply voltage range of 4.5 V to 5.5 V, supporting a propagation delay of 8.5 ns. It provides high drive capability with output currents of ±24 mA. The component is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual positive-edge-triggered D-type flip-flops with independent clear and preset controls
• TTL-compatible input logic levels ensuring direct interfacing with standard logic families
• CMOS output structure providing robust drive current capabilities

Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• General-purpose digital storage elements

Procurement Notes

Verify the specific suffix 'SR' indicates tape-and-reel packaging when sourcing components. Confirm that the SOP package width matches the design footprint requirements. Ensure the supply voltage remains strictly within the 4.5 V to 5.5 V operational limits to maintain signal integrity and prevent device damage during operation.

Selection Notes

Select this component when dual edge-triggered storage is required with TTL input compatibility. The ACT series offers faster switching speeds compared to standard LS logic while maintaining low power consumption. Consider the SOP package format for surface-mount assembly constraints and verify thermal performance within the specified industrial temperature range.

Part Context

This part belongs to the Texas Instruments 74ACT family of advanced CMOS logic devices. The 74ACT11074 specifically provides two independent D-type flip-flops in a single package. It serves as a core building block for sequential logic designs requiring precise timing control and data retention capabilities in digital systems.

Replacement Considerations

Compatible alternatives include the SN74ACT11074N (PDIP) and SN74ACT11074D (SOIC). Verify pinout compatibility and electrical specifications before substitution. Ensure the replacement part supports the same voltage and temperature ranges.
