SEMICONDUCTOR TECHNICAL DATA
Octal 3-State Non-Inverting Transparent Latch
High–Performance Silicon–Gate CMOS
The MC54/74HC373A is identical in pinout to the LS373. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. These latches appear 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.
