74ACTQ16245 16-Bit Transceiver with 3-STATE Outputs
May 1991
Revised November 1999
74ACTQ16245
16-Bit Transceiver with 3-STATE Outputs
General Description
The ACTQ16245 contains sixteen non-inverting bidirec-
tional buffers with 3-STATE outputs and is intended for bus
oriented applications. The device is byte controlled. Each
has separate control inputs which can be shorted together
for full 16-bit operation. The T/R inputs determine the direc-
tion of data flow through the device. The OE inputs disable
both the A and B ports by placing them in a high imped-
ance state.
The ACTQ16245 utilizes Fairchild Quiet Series錚?technol-
ogy to guarantee quiet output switching and improved
dynamic threshold performance. FACT Quiet Series錚?fea-
tures GTO錚?output control for superior performance.
