Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DGVR' corresponds to the TVSOP-14 package and tape-and-reel carrier configuration. Confirm that the RoHS compliance status and lead finish match project requirements, as these attributes are explicitly defined in the manufacturer's packaging information addendum.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring low-voltage operation between 1.65 V and 3.6 V. It is suitable for applications demanding high-speed data transfer with minimal latency. Ensure the design accommodates the specified thermal impedance and power dissipation characteristics for the TVSOP-14 package under expected load conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ALVC125 family of quadruple bus buffers. It shares functional similarities with other logic families but is optimized for lower voltage ranges compared to standard CMOS devices. The DGVR suffix specifically denotes the plastic small-outline variant with gull-wing leads arranged in a 14-pin configuration.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the output-enable input affect the device state?

Each output is disabled when the associated output-enable (OE) input is high, ensuring a high-impedance state.

What is the recommended method to ensure high-impedance during power up or down?

The OE pin should be tied to VCC through a pullup resistor, with the minimum value determined by the driver's current-sinking capability.
