74LV125DB,112

Overview

The 74LV125DB,112 is a low-voltage Si-gate CMOS quad buffer and line driver manufactured by NXP USA Inc. It features four non-inverting buffers with three-state outputs controlled by active-low output enable inputs (nOE). The device operates within a supply voltage range of 1.0 V to 5.5 V and is pin-compatible with 74HC125 and 74HCT125 families. It supports TTL input levels between 2.7 V and 3.6 V. The component is housed in an SSOP14 package (SOT337-1) and is rated for ambient temperatures from -40 °C to +85 °C.

Feature Summary

• Provides four non-inverting buffer/line drivers with three-state outputs
• Accepts TTL input levels when operating between 2.7 V and 3.6 V
• Offers ESD protection exceeding 2000 V via Human Body Model standard

Applications

• Low voltage applications requiring wide operating voltage support
• Mixed signal systems utilizing TTL logic interfaces
• High impedance bus isolation using three-state control

Procurement Notes

Verify the specific ordering suffix and package variant against current NXP documentation before integration. Confirm that the SSOP14 thermal derating characteristics align with the target system's power dissipation requirements. Ensure the selected temperature range meets the operational environment specifications. Cross-reference the latest datasheet revision to confirm functional compatibility with existing designs.

Selection Notes

Select this component for designs requiring wide voltage operation down to 1.0 V. It serves as a direct replacement for HC/HCT variants where lower voltage thresholds are necessary. Consider the SSOP14 package dimensions for PCB layout constraints. Verify that the required propagation delay and enable times fit the system timing budget at the intended supply voltage.

Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices produced by NXP Semiconductors. The series is designed for applications demanding operation below standard 5 V logic levels while maintaining compatibility with higher voltage interfaces. The DB suffix specifically denotes the SSOP14 plastic shrink small outline package configuration.

Replacement Considerations

The 74LV125D is functionally equivalent but utilizes an SO14 package instead of SSOP14. Designers must verify footprint compatibility if substituting packages. Other family members like the 74LV126 offer similar buffering but with different output enable polarity.
