Description

The 74LVC2G126 is a high-performance, low-power, low-voltage, Si-gate CMOS device and superior to most advanced CMOS compatible TTL families.

Inputs can be driven from either 3.3 V or 5 V devices. These feature allows the use of these devices as translators in a mixed 3.3 V and 5 V environment.

The 74LVC2G126 is fully specified for partial power-down applications using I_off. The I_off circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.

The 74LVC2G126 provides a dual non-inverting buffer/line driver with 3-state output. The 3-state output is controlled by the output enable input (pin nOE). A LOW-level at pin nOE causes the output to assume a high-impedance OFF-state. Schmitt-trigger action at all inputs makes the circuit highly tolerant for slower input rise and fall times.
