3.3V ABT Octal Buffers/Drivers With 3-State Outputs

These octal Buffers drivers are designed specifically for low-voltage (3.3-V) VCC operation, but with the capability to provide a TTL Interface to a 5-V system environment.
The SN74LVTH540 devices are ideal for driving bus lines or Buffer memory address Registers These devices feature inputs and outputs on opposite sides of the package that facilitate printed circuit board layout.
The 3-state control Gate is a 2-input AND Gate with active-low inputs so that if either output-enable (OE1 or OE2) input is high, all outputs are in the high-impedance state.
Active bus-hold circuitry holds unused or undriven inputs at a valid Logic state. Use of pullup or pulldown resistors with the bus-hold circuitry is not recommended.
When VCC is between 0 and 1.5 V, the devices are in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 1.5 V, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
These devices are fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down. The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down, which prevents driver conflict.
