description
This 16-bit buffer/driver is designed for 1.65-V to
3.6-V V
CC
operation.
The SN74ALVCH16244 is designed specifically
to improve the performance and density of 3-state
memory address drivers, clock drivers, and
bus-oriented receivers and transmitters.
The device can be used as four 4-bit buffers, two
8-bit buffers, or one 16-bit buffer. It provides true
outputs
and
symmetrical
output-enable (OE) inputs.
active-low
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.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN74ALVCH16244 is characterized for operation from –40
°
C to 85
°
C.
