74LVT126DB,112

Overview

The Nexperia 74LVT126DB,112 is a quad buffer and line driver featuring three-state outputs controlled by active-low output enable inputs (nOE). It operates within a supply voltage range of 2.7 V to 3.6 V. The device incorporates bus-hold data inputs to eliminate the need for external pull-up resistors on unused lines. It supports partial power-down applications via IOFF circuitry, which disables outputs to prevent damaging backflow current. The component provides overvoltage tolerant inputs up to 5.5 V and offers high-speed BiCMOS performance with an output capability of +64 mA and -32 mA.

Feature Summary

• Quad bus interface with three-state buffers
• Overvoltage tolerant inputs up to 5.5 V
• Bus-hold data inputs eliminate external pull-up requirements
• IOFF circuitry enables partial power-down mode operation

Applications

• Partial power-down system architectures
• Mixed voltage bus interfaces
• Line driving in 3.3 V logic environments

Procurement Notes

Verify the specific ordering suffix '112' against the manufacturer's latest documentation to confirm package type and tape-and-reel specifications. Ensure that the SO14 plastic small outline package variant matches the required PCB footprint dimensions. Confirm compliance with RoHS directives and REACH regulations prior to final procurement decisions.

Selection Notes

Select this component when a quad buffer with three-state control is required for 3.3 V systems interfacing with 5 V buses. The inclusion of bus-hold inputs simplifies design by removing external pull-up components. Verify that the operating temperature range of -40 °C to +85 °C meets the environmental requirements of the target application.

Part Context

This part belongs to the 74LVT series of low-voltage TTL-compatible logic devices manufactured by Nexperia. The 74LVT family is designed for high-speed applications requiring wide supply voltage ranges and robust output drive capabilities. The 74LVT126 specifically functions as a non-inverting buffer, providing signal isolation and level shifting between different voltage domains within electronic circuits.

Replacement Considerations

The 74LVT126PW is a pin-compatible alternative available in a TSSOP14 package.
