74ABT377AD,118

Flip Flops Overview

The 74ABT377AD,118 is a high-speed octal D-type flip-flop with positive-edge triggering and three-state outputs, manufactured by NXP USA Inc. under the 74ABT series. It operates within a supply voltage range of 4.5V to 5.5V and features a propagation delay of 4ns at 5V with 50pF load. The device supports a clock frequency up to 260 MHz and provides output drive currents of 32mA (high) and 64mA (low). Packaged in a 20-SOIC surface-mount format, it functions reliably across an industrial temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type storage elements within a single integrated circuit package.
• Positive-edge triggering mechanism ensures data capture occurs precisely on the rising edge of the clock signal.
• Three-state output architecture allows for direct bus driving capabilities without additional external buffering components.

Flip Flops Applications

• High-speed parallel data storage and register operations in digital logic systems
• Interface buffering between microprocessors and peripheral devices requiring tri-state control
• Clock distribution networks utilizing positive-edge triggered data latching

Flip Flops Procurement Notes

Verify component authenticity through authorized NXP distributors or certified partners. Confirm RoHS3 compliance status prior to integration. Check current production status as availability may vary; obsolete variants require lifecycle assessment. Ensure packaging specifications match design requirements for surface-mount assembly processes.

Flip Flops Selection Notes

Select this component for applications demanding high-speed data retention with minimal propagation delay. The ABT series offers superior performance compared to standard TTL equivalents. Consider the 20-SOIC package dimensions for PCB layout constraints. Evaluate power consumption characteristics against system thermal limits during continuous operation at maximum clock frequencies.

Flip Flops Part Context

This part belongs to the 74ABT family of advanced BiCMOS logic devices, designed for high-speed applications. The 74ABT377 specifically implements octal flip-flops, distinguishing it from latches or gates within the same series.
