SN74LVC125ADG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC125ADG4 is a quadruple bus buffer gate with 3-state outputs manufactured by Texas Instruments. It operates from 1.65V to 3.6V and features independent output-enable inputs for each buffer. The device accepts input voltages up to 5.5V, enabling voltage translation in mixed 3.3V/5V systems. It is specified for operation from -40°C to 85°C and -40°C to 125°C. The maximum propagation delay is 4.8ns at 3.3V. Typical output ground bounce is 2V at VCC = 3.3V. Latch-up performance exceeds 250mA per JESD 17. It is housed in a 14-pin SOIC package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DG4' corresponds to the RoHS-compliant lead finish (NIPDAU) and tube packaging configuration. Confirm the operating temperature range requirements match the datasheet specifications of -40°C to 85°C or -40°C to 125°C. Ensure the design accounts for the recommended bypass capacitor placement near the VCC pin to prevent power disturbances during operation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quadruple non-inverting buffer with high-impedance states is required for 1.65V to 3.6V logic systems. It is suitable for applications needing voltage translation between 3.3V and 5V domains due to its 5.5V tolerant inputs. Consider the SOIC-14 package dimensions and thermal resistance values if board space or heat dissipation are critical constraints in the layout.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC125A family of quadruple bus buffer gates. The 'DG4' suffix indicates a specific manufacturing variant within the Texas Instruments portfolio, typically denoting RoHS compliance and a specific lead finish. It shares functional characteristics with other members of the LVC series but differs in physical packaging and environmental certifications.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle power-up or power-down 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 latch-up performance specification?

Latch-up performance exceeds 250mA per JESD 17 standard.
