74ACTQ16373
16-Bit Transparent Latch with 3-STATE Outputs
General Description
The ACTQ16373 contains sixteen non-inverting latches
with 3-STATE outputs and is intended for bus oriented
applications. The device is byte controlled. The flip-flops
appear transparent to the data when the Latch Enable (LE)
is HIGH. When LE is low, the data that meets the setup
time is latched. Data appears on the bus when the Output
Enable (OE) is LOW. When OE is HIGH, the outputs are in
high Z state. The ACTQ16373 utilizes Fairchild鈥檚 Quiet
Series錚?technology to guarantee quiet output switching
and improved dynamic threshold performance. FACT Quiet
Series錚?features GTO錚?output control for superior perfor-
mance.
