MN54ACT373-X REV 1B0 MICROCIRCUIT DATA SHEET
Octal Transparent Latch With 3-State Outputs
General Description
The ACT373 consists of eight latches with 3-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.

Note 1: Absolute maximum ratings are those values beyond which damage to the device may
occur. The databook specifications should be met, withouT exception, to ensure that
the system design is reliable over its power supply, temperature, and output/input
loading variables. National does not recommend operation of FACT TM circuits outside
databook specifications.
