MC74HC373ADTG

The MC74HC373ADTG is an octal 3-state non-inverting Transparent Latch identical in pinout to the LS373. The device inputs are compatible with standard CMOS outputs, with pull-up resistors, they are compatible with LSTTL outputs. It appears transparent to data (i.e., the outputs change asynchronously) when Latch Enable is high. When Latch Enable goes low, data meeting the setup and hold time becomes latched. The Output Enable input does not affect the state of the latches, but when Output Enable is high, all device outputs are forced to the high-impedance state. Thus, data may be latched even when the outputs are not enabled. The HC373A is identical in function to the HC573A which has the data inputs on the opposite side of the package from the outputs to facilitate PC board layout. The HC373A is the non-inverting version of the HC533A.
