SN74ABT377APW

Flip Flops Overview

The SN74ABT377APWR is an octal D-type edge-triggered flip-flop with clock enable, manufactured by Texas Instruments. It belongs to the ABT logic series and features TTL-compatible inputs and outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a maximum propagation delay of 6.8 ns at 5 V with 50 pF load, a high-level output current of -32 mA, and a low-level output current of 64 mA. The static current (Iq) is specified at 250 µA. It is housed in a 20-pin TSSOP package and supports surface-mount installation.

Flip Flops Feature Summary

• Octal D-type edge-triggered flip-flop architecture with integrated clock enable functionality for precise data synchronization control.

Flip Flops Applications

• High-speed parallel data storage and buffering in digital systems
• Interface circuits requiring TTL-compatible I/O levels
• Memory address latching applications

Flip Flops Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape/reel specifications. Ensure compatibility with the target PCB footprint and reflow soldering profile. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Cross-reference the ordering part number with the datasheet to validate pinout and electrical characteristics match the design requirements.

Flip Flops Selection Notes

Select this component when designing systems requiring fast switching speeds and high drive capability. The ABT series offers superior performance compared to standard 74-series logic. Consider the 20-lead TSSOP package for space-constrained surface-mount designs. Verify that the 4.5 V to 5.5 V operating range aligns with the system power supply. Evaluate the 6.8 ns propagation delay against the system timing constraints.

Flip Flops Part Context

This component is part of the SN74ABT377A family of octal flip-flops. It shares functional similarities with other devices in the 74ABT logic family but is distinguished by its specific package configuration and suffix designation. The 'PWR' suffix typically indicates a TSSOP package with reel packaging, differentiating it from SOIC or SSOP variants like the ADW or ADBR.
