SN74ALVC125PWE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVC125PWE4 is a quadruple bus buffer gate with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage range of 1.65 V to 3.6 V and features independent line drivers. The device provides an output drive capability of ±24 mA at 3.6 V. Each output is disabled when the associated output-enable (OE) input is high. The component is housed in a 14-pin TSSOP package and supports an operating free-air temperature range of -40 °C to 85 °C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix 'E4' corresponds to the specific lead finish and RoHS compliance requirements mandated by your assembly process. Confirm the package type matches the PCB footprint design, as the PW designation indicates a TSSOP housing. Ensure the selected variant aligns with the required thermal impedance and moisture sensitivity level ratings for your manufacturing environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require low-power logic operation within the 1.65 V to 3.6 V supply range. It is suitable for applications needing high-speed signal buffering with propagation delays as low as 2.8 ns at 3.3 V. Consider the ±24 mA output drive capability for driving moderate capacitive loads on system buses without external amplification.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the ALVC logic family, which is designed for low-voltage CMOS applications. It serves as a quadruple bus buffer gate, providing three-state outputs controlled by individual enable inputs. The device is intended for use in portable and battery-operated equipment where power consumption is a critical design constraint.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the OE input control the output state?

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

What is the maximum propagation delay at 3.3 V?

The maximum propagation delay (t_pd) is 2.8 ns when operating at a supply voltage of 3.3 V.
