MC54HC534A

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Octal 3-State Inverting D Flip-Flop High–Performance Silicon–Gate CMOS The MC54/74HC534A is identical in pinout to the LS534. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL 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 are forced to the high impedance state. Thus, data may be stored even when the outputs are not enabled. The HC534A is identical in function to the HC564 which has the data inputs on the opposite side of the package from the outputs to facilitate PC board layout. This device is similar in function to the HC374A, which has noninverting outputs. Output Drive Capability: 15 LSTTL Loads Outputs Directly Interface to CMOS, NMOS and TTL Operating Voltage Range: 2.0 to 6.0 V...
