description/ordering information
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 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 series damping resistors to reduce
overshoot and undershoot.
The ALVCHS162830A is an improved version of
the LVCHS162830 (non-A version) and has been
optimized for lower power consumption and
higher AC drive. Higher AC drive provides
capability to drive loads with a faster edge rate.
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.
