SN74LVC125ADT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC125ADT is a quadruple bus buffer gate with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage of 1.65V to 3.6V and features independent output-enable inputs for each buffer. The device accepts input voltages up to 5.5V, allowing compatibility with 3.3V or 5V driving devices. It provides balanced output drive capabilities and includes latch-up performance exceeding 250mA per JESD 17. The component is housed in a 14-pin SOIC package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DT' corresponds to the 14-pin SOIC package with small tape-and-reel carrier. Confirm the active production status and lead finish specifications (NIPDAU) match the design requirements. Ensure the moisture sensitivity level (MSL 1) aligns with the assembly process constraints.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this part when a quad bus buffer with 3-state control is required for 1.65V to 3.6V logic families. The 5.5V tolerant inputs make it suitable for translating signals between different voltage domains. Consider the SOIC-14 package dimensions and thermal resistance values if board space or heat dissipation are critical factors in the layout.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the SN74LVC125A family of quadruple bus buffers. The 'ADT' designation specifically identifies the SOIC (D) package variant supplied in a small tape-and-reel format containing 250 units. It shares functional characteristics with other LVC series buffers but differs in physical packaging and shipping quantity.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle power-up states?

To ensure the high-impedance state during power up or power down, the OE input should be tied to VCC through a pullup resistor.

What is the maximum input voltage tolerance?

The inputs can accept voltages up to 5.5V, regardless of the VCC supply voltage within the operating range.
