The SN74LVT125PW 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 high. 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. This device is fully specified for partial-power-down applications using IOFF. The IOFF circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. To ensure the high-impedance state during power up or power down, OE\ should be tied to VCC through a pull-up resistor and the minimum value of the resistor is determined by the current-sinking capability of the driver.
● Supports mixed-mode signal operation
● IOFF Supports partial-power-down mode operation
● Bus-hold data inputs eliminate the need for external pull-up resistor
● Latch-up performance exceeds 500mA per JEDEC standard JESD-17
● Supports unregulated battery operation down to 2.7V
● <0.8V at VCC = 3.3V, TA = 25°C VOLP (output ground bounce)
● Green product and no Sb/Br
