74ABT377AN,112

Flip Flops Overview

The SN74ABT377AN,112 is an octal D-type edge-triggered flip-flop manufactured by NXP USA Inc. under the ABT logic series. It features a non-inverting output configuration with TTL-compatible input and output levels. The device operates within a supply voltage range of 4.5 V to 5.5 V and includes a clock enable function for data control. Packaged in a PDIP-20 through-hole format, it supports a wide operating temperature range from -40°C to +85°C. Key electrical characteristics include a propagation delay of 6.8 ns, a high-level output current capability of -32 mA, and a low-level output current of 64 mA.

Flip Flops Feature Summary

• Octal D-type edge-triggered flip-flop architecture
• Clock enable functionality for data gating
• TTL-compatible input and output interfaces
• Robust drive strength with specified output currents

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register file implementations in digital systems
• Data buffering and storage applications
• Timing synchronization modules

Flip Flops Procurement Notes

Verify that the part number suffix matches the specific manufacturer designation, as NXP and Texas Instruments both produce variants of this component type. Confirm the package style corresponds to the required PCB footprint, specifically distinguishing between the PDIP-20 through-hole package and other available options. Ensure the ordering information aligns with the intended supply voltage and temperature range requirements for the target application environment.

Flip Flops Selection Notes

Select this component when an octal register with clock enable is required for TTL-level interfacing. The ABT series offers improved speed compared to standard 74-series logic while maintaining compatibility. Consider the through-hole packaging constraint if surface-mount alternatives are not suitable for the assembly process. Evaluate the drive current capabilities against the load requirements to ensure signal integrity across the eight channels.

Flip Flops Part Context

This component belongs to the 74ABT family of high-speed BICMOS logic devices. It serves as a fundamental building block for sequential logic operations in digital electronics. Similar parts in the series include the 74ABT374, which lacks the clock enable feature, and the 74ABT373, which utilizes latch-based rather than edge-triggered operation. The ABT series bridges the performance gap between older TTL technologies and modern CMOS solutions.

Flip Flops Replacement Considerations

The SN74ABT377N is a direct equivalent from Texas Instruments. Verify pinout compatibility and electrical specifications before substitution. Other potential replacements may include variants from different manufacturers offering the same logical function and package style.
