SN74AC574NSR

Flip Flops Overview

The SN74AC574NSR is an octal edge-triggered D-type flip-flop manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features three-state outputs. The device provides a propagation delay of 13.5 ns, with high-level and low-level output currents of -24 mA and 24 mA respectively. It is housed in a TSSOP-20 package and supports surface-mount installation. The component functions reliably across a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit.
• Three-state outputs enable direct connection to bus lines for efficient data management.
• Edge-triggered operation ensures data capture occurs specifically at the positive transition of the clock signal.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Buffering and latching operations in digital systems
• General-purpose register implementations

Flip Flops Procurement Notes

Verify that the specific ordering suffix matches the required package type and tape-and-reel specifications. Confirm compliance with RoHS directives and material declarations as stated in the official documentation. Ensure the supplier provides valid traceability for the Texas Instruments manufacturer identification before finalizing acquisition.

Flip Flops Selection Notes

Select this component when an octal storage solution with three-state capability is required. The AC series offers faster switching speeds compared to standard HC logic while maintaining CMOS compatibility. Consider the TSSOP-20 package constraints and thermal performance requirements relative to the operating environment.

Flip Flops Part Context

This part belongs to the SN74AC574 family of octal D-type flip-flops. It serves as a semiconductor logic device designed for high-speed digital applications. The component integrates eight separate flip-flops, each equipped with a D input, a clock input, and complementary Q and /Q outputs, alongside a common three-state control line.

Flip Flops FAQ

What is the function of the OE pin?

The OE (Output Enable) pin controls the three-state nature of the outputs. When active, it allows the flip-flop states to drive the output pins; when inactive, the outputs enter a high-impedance state.

How does the device handle clock signals?

The SN74AC574NSR utilizes positive-edge triggering. Data present at the D inputs is transferred to the outputs only upon the rising edge of the clock signal.
