Octal 3-State Noninverting Transparent Latch
High-Performance Silicon-Gate CMOS
The SL74HC373 is identical in pinout to the LS/ALS373. The device
inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LS/ALSTTL 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.
