SN74ABT377ANSR

Flip Flops Overview

The SN74ABT377ANSR is an octal edge-triggered D-type flip-flop with three-state outputs manufactured by Texas Instruments. It belongs to the ABT logic series and operates within a supply voltage range of 4.5 V to 5.5 V. The device features a propagation delay of 6.8 ns at 5 V with 50 pF load, high drive capability with -32 mA high-level output current and 64 mA low-level output current, and non-inverting polarity. It is housed in a 20-SOIC package and supports surface-mount installation.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single package
• Three-state outputs allowing direct bus-driven connections without external buffers
• Positive-edge triggering mechanism for precise data capture timing
• High-current drive capability suitable for demanding digital loads

Flip Flops Applications

Flip Flops Procurement Notes

Verify the exact part number against manufacturer datasheets to confirm pinout compatibility and electrical specifications. Ensure the SOIC-20 package dimensions match your PCB footprint requirements. Check RoHS compliance status if environmental regulations apply to your manufacturing process. Confirm operating temperature ranges align with your specific application environment.

Flip Flops Selection Notes

Select this component when an octal register with three-state outputs is required for 5V logic systems. Consider the ABT series for improved speed compared to standard 74LS equivalents. Evaluate the 6.8 ns propagation delay against your system clock requirements. Ensure the 4.5 V to 5.5 V supply voltage range matches your power distribution network.

Flip Flops Part Context

This component is part of Texas Instruments' SN74ABT family, which combines advanced TTL-compatible performance with CMOS low power consumption. The ABT series offers faster switching speeds than previous generations while maintaining compatibility with standard logic interfaces. The SN74ABT377 variant specifically provides octal storage functionality with tri-state control for efficient bus management.
