54ACTQ16373
16-Bit Transparent Latch with TRI-STATE^®Outputs
General Description
The ’ACTQ16373 contains sixteen non-inverting latches with
TRI-STATE outputs and is intended for bus oriented applica-
tions. 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 NSC Quiet Series technol-
ogy to guarantee quiet output switching and improved dy-
namic threshold performance. FACT Quiet Series™ features
GTO™output control for superior performance.
