Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'TPWT' against the manufacturer's official documentation to confirm tape-and-reel packaging details and pin configuration. Ensure compatibility with design-in requirements regarding thermal performance and ESD protection ratings before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad buffer with three-state capability is required for bus applications. It is suitable for designs needing operation across a wide voltage range from 2.0 V to 5.5 V. Consider the TSSOP-14 package size if space constraints allow, and verify that the 16.5 ns propagation delay meets the system timing requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV125 family of quad bus buffers with three-state outputs. It is designed for low-voltage applications and offers improved switching speeds compared to older CMOS technologies. The device is commonly used in embedded systems where signal integrity and voltage translation are critical.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the function of the OE (Output Enable) pin?

The OE pin controls the state of the outputs. When OE is low, the buffers are active and transmit data. When OE is high, the outputs enter a high-impedance state, effectively disconnecting them from the bus.

Can this device perform level translation?

Yes, the SN74LV125ATPWT supports bidirectional level translation. It can accept inputs up to 5.5 V even if the supply voltage (VCC) is lower, allowing it to interface between different voltage domains.
