SN74ABT377APWR

Flip Flops Overview

The SN74ABT377APWR is an octal D-type edge-triggered flip-flop from the Texas Instruments ABT logic series. It features eight non-inverting outputs and a clock enable input, housed in a TSSOP-20 surface-mount package. 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, high-level output current of -32 mA, and low-level output current of 64 mA. It supports a maximum clock frequency of 150 MHz and functions across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops for parallel data storage.

Flip Flops Applications

• Parallel-to-serial data conversion circuits

Flip Flops Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-20 package and reel packaging format required for your assembly process. Confirm that the ABT logic family voltage compatibility aligns with your system's 4.5 V to 5.5 V power rails. Ensure thermal management meets the -40°C to +85°C industrial temperature specifications during operation.

Flip Flops Selection Notes

Select this component when an octal register with clock enable functionality is required in a compact surface-mount form factor. The ABT series offers improved speed and drive capability compared to standard TTL families. Verify that the 6.8 ns propagation delay and 150 MHz clock limit satisfy your system timing requirements.

Flip Flops Part Context

Flip Flops FAQ

What is the function of the clock enable input?

The clock enable input controls whether the flip-flops respond to the clock signal, allowing data to be held or updated based on the enable state.

Does the SN74ABT377APWR have three-state outputs?

No, the SN74ABT377APWR provides standard non-inverting outputs without three-state capability.
