74ACT11074N

Overview

The SN74ACT11074N is a dual positive-edge-triggered D-type flip-flop from the Texas Instruments ACT 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 complementary outputs and includes set and reset functions. Packaged in a 14-pin PDIP, it supports through-hole mounting. Key electrical specifications include a maximum propagation delay of 8.5 ns at 5 V, output drive currents of ±24 mA, and a static current of 4 µA. It is rated for operation between -40°C and +85°C.

Feature Summary

• Dual positive-edge-triggered D-type flip-flops with complementary outputs
• TTL-compatible input thresholds for direct interfacing with TTL systems
• Integrated asynchronous set and reset control functions
• High noise immunity and low power consumption characteristic of ACT technology

Applications

• Parallel-to-serial data conversion circuits
• Shift register construction
• Timing and synchronization logic applications
• General-purpose digital storage elements

Procurement Notes

Verify the specific package type against project requirements, as the 'N' suffix denotes a plastic DIP package. Confirm that the manufacturer datasheet aligns with the ordered part number to ensure correct pinout and electrical characteristics. Check for RoHS compliance status if required by assembly standards. Ensure the supplier provides official documentation rather than third-party summaries for accurate parameter validation.

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 or HC families while maintaining lower power dissipation. Consider the PDIP package only for through-hole designs; surface-mount variants like the 'D' suffix should be chosen for SMD applications. Verify that the 5V supply rail matches the system design constraints.

Part Context

This device belongs to the SN74ACT series, which combines the high-speed performance of Advanced CMOS with the low power consumption of standard CMOS. It is functionally compatible with the older SN74S174 and SN74LS174 devices, allowing for potential upgrades in existing designs. The ACT family is designed for high-density applications requiring fast propagation delays and robust noise margins.

Replacement Considerations

The SN74ACT11074DE4 is an equivalent lead-free variant of the same component. Other manufacturers may offer pin-compatible alternatives within the 74ACT logic family, but electrical parameters must be verified against the original datasheet.
