SN74LVTH125DBR概述

3.3 -V ABT翻两番总线缓冲器,三态输出 3.3-V ABT QUADRUPLE BUS BUFFERS WITH 3-STATE OUTPUTS

The 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. 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 VCC through a pull-up resistor and the minimum value of the resistor is determined by the current-sinking capability of the driver. The IOFF circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
