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.
