description
This 1-bit-to-2-bit address driver is designed for
2.3-V to 3.6-V V
CC
operation.
Active bus-hold circuitry is provided to hold
unused or floating inputs at a valid logic level.
To ensure the high-impedance state during power
up or power down, OE 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 SN74ALVCH16830 is packaged in TI’s thin
shrink small-outline (DBB) package, which
provides twice the I/O pin count and functionality
of standard small-outline packages in the same
printed-circuit-board area.
The SN74ALVCH16830 is characterized for
operation from –40
°
C to 85
°
C.
