74ACT16240
16-Bit Inverting Buffer/Line Driver with 3-STATE Outputs
General Description
The ACT16240 contains sixteen 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
s 16-bit version of the ACT240
s Outputs source/sink 24 mA
s TTL-compatible inputs

Functional Description
The ACT16240 contains sixteen inverting buffers with 3-
STATE standard outputs. The device is nibble (4 bits) con-
trolled with each nibble functioning identically, but indepen-
dently of the other. The control pins may be shorted
together to obtain full 16-bit operation. The 3-STATE out-
puts 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.
