description
This 1-bit to 2-bit address driver is designed for
2.3-V to 3.6-V V_CC operation.
Diodes to V_CC have been added on the inputs to
clamp overshoot.
Active bus-hold circuitry is provided to hold
unused or floating data inputs at a valid logic level.
The outputs, which are designed to sink up to
12 mA, include equivalent 26-Ω 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 V_CC through a pullup resistor; the
minimum value of the resistor is determined by the
current-sinking capability of the driver.
The SN74ALVCHS162830 is characterized for
operation from –40°C to 85°C.
