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
• Low Input Current: 1.0 µA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
• Chip Complexity: 282 FETs or 68.5 Equivalent Gates

This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high–impedance circuit. For proper operation, Vin and
V
out
should be constrained to the
range GND v (Vin or V
out
) v VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.
