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.
