74LV125PW,112

Buffers, Drivers, Receivers, Transceivers Overview

The NXP USA Inc. 74LV125PW,112 is a low-voltage Si-gate CMOS quad buffer and line driver featuring non-inverting outputs with 3-state control via the nOE input. It operates within a supply voltage range of 1.0 V to 5.5 V and accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V. The device provides four channels in a TSSOP14 package (SOT402-1). Static characteristics specify an input leakage current of up to 1.0 μA at VCC = 5.5 V and a supply current of up to 160 μA under maximum conditions. Dynamic performance includes propagation delays ranging from 9 ns to 31 ns depending on voltage and load.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package type, as the base part number covers multiple packages. Confirm the temperature range specification aligns with system requirements, noting the device supports -40 °C to +125 °C. Ensure input voltage levels are compatible with the target logic family, particularly when operating below 3.6 V where TTL compatibility may not apply.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a wide operating voltage range from 1.0 V to 5.5 V is required alongside 3-state output capability. It is suitable for applications needing high noise immunity due to ESD protection ratings. Consider the TSSOP14 package constraints regarding thermal derating above 60 °C if power dissipation limits are approached.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74LV series of low-voltage CMOS logic components manufactured by NXP Semiconductors. The 74LV125 specifically functions as a quad buffer with 3-state outputs, designed to interface between different voltage domains or drive high-capacitance loads while maintaining signal integrity across a broad supply voltage spectrum.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The datasheet explicitly states the 74LV125 is pin and function compatible with the 74HC125 and 74HCT125. These can be considered for replacement if voltage level shifting or specific LV characteristics are not strictly required.
