74LV125DB,118

Overview

The 74LV125DB,118 is a low-voltage Si-gate CMOS quad buffer and line driver manufactured by NXP USA Inc. It features four non-inverting buffers with 3-state outputs controlled by an active-low output enable input (nOE). The device 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. It is housed in an SSOP14 package (SOT337-1) and supports operating temperatures from -40 °C to +125 °C.

Feature Summary

• Provides four non-inverting buffer/line drivers with 3-state outputs
• Wide operating voltage range from 1.0 V to 5.5 V
• Accepts TTL input levels when VCC is between 2.7 V and 3.6 V
• ESD protection exceeds 2000 V per HBM and 200 V per MM

Applications

• Low voltage applications requiring wide voltage compatibility
• TTL-to-CMOS level translation interfaces
• High-impedance bus driving and signal buffering

Procurement Notes

Verify the specific ordering suffix '118' corresponds to the SSOP14 package variant SOT337-1 as defined in the official NXP datasheet. Confirm that the required temperature range (-40 °C to +125 °C) matches the standard specification for this part number. Ensure design compliance with the absolute maximum ratings regarding supply voltage and current limits to prevent device damage.

Selection Notes

Select this component for designs requiring pin-and-function compatibility with 74HC125 and 74HCT125 while supporting lower supply voltages down to 1.0 V. It is suitable for mixed-voltage environments where TTL input levels must be processed at VCC values between 2.7 V and 3.6 V. Consider the SSOP14 package constraints for board space and thermal dissipation requirements.

Part Context

This device belongs to the 74LV series of low-voltage CMOS logic components. It serves as a direct functional replacement for 74HC125 and 74HCT125 devices, offering improved performance in low-voltage systems. The 74LV125 family is designed for general-purpose buffering and line driving applications across industrial and consumer electronics.

Replacement Considerations

The 74LV125 is pin and function compatible with 74HC125 and 74HCT125.
