Octal 3-State Inverting Transparent Latch
High- Performance Silicon- Gate CMOS
The MC54/74HC533A is identical in pinout to the LS533. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LSTTL outputs. These latches appear transparent to data (i.e., the outputs change asynchronously) when Latch Enable is high. The Data appears at the outputs in inverted form. When Latch Enable goes low, data meeting the setup and hold time bees 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....
