SN74ABT377AN

Flip Flops Overview

The SN74ABT377AN is an octal D-type edge-triggered flip-flop featuring a clock enable function, manufactured by Texas Instruments. It belongs to the ABT logic series and utilizes a 20-pin PDIP package for through-hole mounting. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 150 MHz. Key electrical parameters include a propagation delay of 6.8 ns, a high-level output current of -32 mA, and a low-level output current of 64 mA. It functions with non-inverting outputs and TTL input levels, maintaining an operating temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Integrates eight independent D-type edge-triggered flip-flops with a dedicated clock enable control mechanism.
• Delivers high-speed data transfer capabilities supported by a 150 MHz maximum clock frequency specification.
• Provides robust output drive strength suitable for direct interfacing with bus structures and loads.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register file implementations in microprocessor systems
• Buffering and latching applications for digital signal paths

Flip Flops Procurement Notes

Verify that the specific part number matches the required through-hole PDIP-20 package configuration rather than surface-mount alternatives. Confirm that the ABT logic family specifications align with the system's voltage and speed requirements. Ensure that the clock enable functionality is correctly utilized in the schematic design to manage data flow timing appropriately.

Flip Flops Selection Notes

Select this component when an octal register with explicit clock gating is required for through-hole PCB designs. The ABT series offers a balance of speed and drive capability superior to standard LS or HC families. Consider the 6.8 ns propagation delay and 150 MHz limit to ensure compatibility with the target system clock rates and signal integrity needs.

Flip Flops Part Context

This device is part of the broader 74ABT377 family of octal flip-flops. Variants such as SN74ABT377ADBR utilize different packaging like SSOP for surface mount applications. The SN74ABT377AN specifically denotes the through-hole PDIP version, distinguishing it from other physical form factors within the same logical architecture and functional specification set.
