MN54ABT373-X REV 0B0 MICROCIRCUIT DATA SHEET
OCTAL TRANSPARENT LATCH WITH TRI-STATE OUTPUTS
General Description
The ABT373 consists of eight latches with TRI-STATE outputs 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.
