Description

The IN74HC534A is identical in pinout to the LS/ALS534. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.

Data meeting the setup time is clocked, in inverted form, to the outputs with the rising edge of the Clock. The Output Enable input does not affect the states of the flip-flops, but when Output Enable is high, the outputs of the IN74HC534A are forced to the high impedance state. Thus, data may be stored even when the outputs are not enabled.
