SN74ABT377ADWR

Flip Flops Overview

The SN74ABT377ADWR is an octal D-type flip-flop manufactured by Texas Instruments, featuring a clock enable input for data control. It operates within a supply voltage range of 4.5V to 5.5V and supports a maximum clock frequency of 150 MHz. The device exhibits a typical propagation delay of 6.8ns at 5V with 50pF load. It provides non-inverting outputs with high drive capability, delivering 32mA output high current and 64mA output low current. The static supply current is specified at 250 µA. Designed for surface-mount applications, it is housed in a 20-SOIC package and functions reliably across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Integrates eight edge-triggered D-type flip-flops with individual data inputs and common clock and clock enable controls.
• Features non-inverting outputs capable of driving standard TTL loads with significant current sourcing and sinking capabilities.
• Incorporates Schmitt trigger inputs on the clock line to improve noise immunity and signal integrity during transitions.

Flip Flops Applications

• Parallel-to-serial or serial-to-parallel data conversion circuits
• High-speed buffering and register stages in digital systems
• Data acquisition systems requiring precise timing and storage

Flip Flops Procurement Notes

Verify the specific ordering suffix 'DWR' corresponds to the SOIC-20 package and tape-and-reel packaging configuration required for your assembly process. Confirm that the component meets RoHS standards if environmental compliance is mandatory for your project. Ensure the selected variant matches the required operating temperature range and electrical specifications defined in the official datasheet before finalizing procurement.

Flip Flops Selection Notes

Select this component when designing systems requiring high-speed data latching with robust output drive strength. The ABT series offers superior performance compared to standard logic families, making it suitable for demanding applications. Consider the 20-SOIC package dimensions for PCB layout constraints. Evaluate the 150 MHz clock limit against your system's timing requirements to ensure reliable operation without violating setup and hold times.

Flip Flops Part Context

This part belongs to the Texas Instruments 74ABT logic family, which utilizes Advanced BiCMOS technology to achieve high speed while maintaining low power consumption. The SN74ABT377A is the octal version of this family, providing eight independent storage elements. It is designed to interface directly with TTL circuits, offering compatibility with existing system architectures while providing enhanced switching speeds and drive capabilities.

Flip Flops Replacement Considerations

The SN74ABT377ADBRE4 is a verified equivalent part number from the same manufacturer. Verify pinout compatibility and electrical parameters before substitution. Other variants within the 74ABT377A family may offer different packages but must be checked for functional equivalence.
