74LVT125PW,118

Overview

The Nexperia 74LVT125PW,118 is a quad buffer and line driver featuring 3-state outputs controlled by active LOW output enable inputs. It operates within a supply voltage range of 2.7 V to 3.6 V and utilizes BiCMOS technology for high-speed performance. The device includes bus hold data inputs to eliminate external pull-up resistors for unused lines and incorporates IOFF circuitry to prevent damaging backflow currents during partial power-down applications. It supports live insertion and extraction without causing bus current loading when tied to a 5 V bus.

Feature Summary

• Quad bus interface with 3-state buffers
• Bus hold data inputs eliminate need for external pull-up resistors
• IOFF circuitry provides partial Power-down mode operation
• Overvoltage tolerant inputs to 5.5 V

Applications

• Partial power down applications
• Live insertion and extraction systems
• Mixed 3.3 V and 5 V bus environments

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74LVT125 series is available in multiple configurations including SO14, TSSOP14, and DHVQFN14. Confirm that the selected variant aligns with the thermal and mechanical constraints of the target PCB design. Ensure compliance with the specified operating temperature range of -40 °C to +85 °C for the intended application environment.

Selection Notes

Select this component for designs requiring a 3.3 V quad buffer with high drive capability and overvoltage tolerance. The inclusion of bus hold inputs simplifies schematic design by removing the need for external pull-up resistors on unused inputs. Consider the TSSOP14 package for space-constrained surface-mount applications while ensuring the supply voltage remains strictly within the 2.7 V to 3.6 V recommended operating conditions.

Part Context

This part belongs to the 74LVT logic family, which is designed for 3.3 V applications. It serves as a buffer/line driver solution compatible with TTL levels. The PW suffix indicates the TSSOP14 plastic thin shrink small outline package (SOT402-1). This family is distinct from LVTH variants only by manufacturing process, sharing identical electrical specifications and functionality.

Replacement Considerations

The 74LVTH125PW,118 is a parameter-equivalent alternative within the same package and specification set.
