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.
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
