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’s Quiet
Seriestechnology to guarantee quiet output switching
and improved dynamic threshold performance. FACT Quiet
Seriesfeatures GTOoutput control for superior perfor-
mance.
Features

s Separate control logic for each byte
s 16-bit version of the ACTQ373
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
