74LVC2G126GT/S500115

Overview

The 74LVC2G126GT is a dual non-inverting buffer and line driver featuring three-state outputs controlled by active HIGH enable inputs (1OE, 2OE). It operates within a supply voltage range of 1.65 V to 5.5 V and utilizes Schmitt-trigger inputs for noise immunity. The device incorporates IOFF circuitry to prevent backflow current during partial power-down states. It supports direct interfacing with TTL levels and complies with JEDEC standards for various voltage domains.

Feature Summary

• Dual non-inverting buffers with three-state outputs
• IOFF circuitry prevents backflow current in partial power-down mode
• Schmitt-trigger inputs provide tolerance for slow rise and fall times
• Inputs tolerate voltages up to 5.5 V for mixed 3.3 V and 5 V environments

Applications

• Mixed 3.3 V and 5 V bus translation
• Partial power-down applications requiring backflow protection
• High-noise immunity signal buffering

Procurement Notes
