16-Bit Transparent Latch with 3-STATE Outputs

Fairchild Semiconductor

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.
