74ACT16540
16-Bit Inverting Buffer/Line Driver with 3-STATE Outputs
General Description
The ACT16540 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 byte controlled. Each byte has sep-
arate 3-STATE control inputs which can be shorted
together for full 16-bit operation.
Features
s Separate control logic for each byte
s Outputs source/sink 24 mA
s TTL-compatible inputs
