Flip Flops datasheet and documents for SN74ALS577ADWR

SN74ALS577ADWR

Flip Flops Overview

The SN74ALS577ADWR is an octal D-type edge-triggered flip-flop with 3-state outputs manufactured by Texas Instruments. It belongs to the ALS logic series and operates within a supply voltage range of 4.5 V to 5.5 V. The device features a propagation delay of 14 ns, with low-level output current capability of 24 mA and high-level output current of -2.6 mA. It is housed in a SOIC-24 surface-mount package and supports an operating temperature range from 0°C to +70°C.

Flip Flops Feature Summary

Octal D-type edge-triggered flip-flop architecture
Three-state output capability for bus driving
TTL input compatibility

Flip Flops Applications

Register storage applications
Bus-oriented memory mapping
Parallel-to-serial data conversion

Flip Flops Procurement Notes

Verify the specific ordering suffix 'R' indicates reel packaging configuration. Confirm RoHS status details through official documentation. Ensure the SOIC-24 package dimensions match the target PCB footprint requirements. Validate that the 4.5V to 5.5V supply range aligns with the system power design specifications.

Flip Flops Selection Notes

Select this component when octal edge-triggered storage with three-state outputs is required. The ALS series offers improved speed over standard LS logic while maintaining TTL input levels. Consider the 14 ns propagation delay and 24 mA sink current for timing and load analysis. The SOIC-24 package is suitable for surface-mount assembly processes.

Flip Flops Part Context

This part is part of the SN74ALS577A family of octal flip-flops. It provides eight D-type flip-flops with positive-edge triggering and three-state outputs. The device is designed for high-speed memory and buffer applications requiring bus hold capabilities.
