74AC16244 74ACT16244
16-Bit Buffer/Line Driver with 3-STATE Outputs
General Description
The AC16244 and ACT16244 contain sixteen non-inverting
buffers with 3-STATE outputs designed to be employed as
a memory and address driver, clock driver, or bus oriented
transmitter/receiver. The device is nibble controlled. Each
nibble has separate 3-STATE control inputs which can be
shorted together for full 16-bit operation.
Features
s Separate control logic for each byte and nibble
s 16-bit version of the AC244/ACT244
s Outputs source/sink 24 mA
s ACT16244 has TTL-compatible inputs

Functional Description
The AC16244 and ACT16244 contain sixteen non-inverting
buffers with 3-STATE standard outputs. The device is nib-
ble (4 bits) controlled with each nibble functioning identi-
cally, but independent of the other. The control pins can be
shorted together to obtain full 16-bit operation. The
3-STATE outputs are controlled by an Output Enable (OEn)
input for each nibble. When OEn is LOW, the outputs are in
2-state mode. When OEn is HIGH, the outputs are in the
high impedance mode, but this does not interfere with
entering new data into the inputs.

Note 1: Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, with-
out exception to ensure that the system design is reliable over its power
supply, temperature, and output/input loading variables. Fairchild does not
recommend operation of FACTcircuits outside databook specifications.
