Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package suffix (RKS, PW, or DGS) matches the required footprint, as electrical performance remains consistent across packages. Confirm AEC-Q100 qualification requirements align with target automotive standards. Ensure design accounts for thermal dissipation limits defined in absolute maximum ratings during high-current operation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing with TTL logic levels requiring noise immunity via Schmitt triggers. Suitable for applications needing simultaneous control of eight channels with independent enable inputs. Consider the wettable flank feature in the RKS package for improved automatic optical inspection reliability compared to standard QFN variants.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74ACT series of logic buffers. It shares functional similarities with other octal buffers but distinguishes itself through integrated Schmitt-trigger inputs and automotive qualification. The ACT series typically offers higher speed and drive capability compared to standard AC logic families.

Buffers, Drivers, Receivers, Transceivers FAQ

How do the OE1 and OE2 pins function?

Both OE1 and OE2 must be low for the outputs to be active. If either pin is high, all outputs enter the high-impedance state.

What is the recommended handling for unused inputs?

Unused inputs must never be left floating. They should be terminated to VCC or GND, preferably using a pull-up or pull-down resistor such as 10kΩ.
