Widebus is a trademark of Texas Instruments.
This 1-bit to 2-bit address driver is designed for 2.3-V to 3.6-V VCC operation.
Diodes to VCC have been added on the inputs to clamp overshoot.
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.
The outputs, which are designed to sink up to 12 mA, include equivalent 26- series resistors to reduce overshoot and undershoot.
To ensure the high-impedance state during power up or power down, the output-enable (OE)\ input 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.
