SN74LVTH126PW

Буфер, неинвертирующий, TTL, 2.7В до 3.6В, TSSOP-14.

The SN74LVTH126PW is a quadruple Bus Buffer designed specifically for low-voltage (3.3V) VCC operation, but with the capability to provide a TTL interface to a 5V system environment. It features independent line drivers with 3-state outputs. Each output is in the high-impedance state when the associated output-enable (OE) input is low. Active bus-hold circuitry holds unused or un-driven inputs at a valid logic state. Use of pull-up/pull-down resistors with the bus-hold circuitry is not recommended. When VCC is between 0 and 1.5V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 1.5V, OE should be tied to GND through a pull-down resistor and the minimum value of the resistor is determined by the current-sourcing capability of the driver. The IOFF circuitry disables the outputs, preventing damaging current backflow through the devices when it is powered down.
