Octal Transparent Latch with TRI-STATE
é
Outputs
General Description
The ’ABT373 consists of eight latches with TRI-STATE out-
puts for bus organized system applications. The flip-flops
appear transparent to the data when Latch Enable (LE) is
HIGH. When LE is LOW, the data that meets the setup
times is latched. Data appears on the bus when the Output
Enable (OE) is LOW. When OE is HIGH the bus output is in
the high impedance state.
