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’s Quiet
Series technology to guarantee quiet output switching
and improved dynamic threshold performance. FACT Quiet
Series features GTO output control for superior perfor-
mance.
Features
a73 Utilizes Fairchild FACT Quiet Series technology
a73 Guaranteed simultaneous switching noise level and
dynamic threshold performance
a73 Guaranteed pin-to-pin output skew
a73 Separate control logic for each byte
a73 16-bit version of the ACTQ373
a73 Outputs source/sink 24 mA
a73 Additional specs for Multiple Output Switching
a73 Output Loading specs for both 50 pF and 250 pF loads
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
