54ABT16373
16-Bit Transparent Latch with TRI-STATE^® Outputs
General Description
The ABT16373 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.
