74ACT16373
16-Bit Transparent Latch with 3-STATE Outputs
General Description
The ACT16373 contains sixteen non-inverting latches with
3-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.
