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 Seriestechnol-
ogy to guarantee quiet output switching and improved
dynamic threshold performance. FACT Quiet Seriesfea-
tures GTOoutput control for superior performance.
Features
s Utilizes Fairchild FACT Quiet Series technology

s Bidirectional non-inverting buffers
s Separate control logic for each byte
s 16-bit version of the ACTQ245
s Outputs source/sink 24 mA
s Additional specs for multiple output switching
s Output loading specs for both 50 pF and 250 pF loads
