High–Performance Silicon–Gate CMOS
The MC74HC564 is identical in pinout to the LS564. The device inputs are
compatible with standard CMOS outputs; with pullup resistors, they are
compatible with LSTTL outputs.
This device is identical in function to the HC534A but has the flip–flop
inputs on the opposite side of the package from the outputs to facilitate PC
board layout.
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, all device outputs are
forced to the high–impedance state. Thus, data may be stored even when
the outputs are not enabled.
The HC564 is the inverting version of the HC574A.
• Output Drive Capability: 15 LSTTL Loads
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2 to 6 V
• Low Input Current: 1 µA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
• Chip Complexity: 282 FETs or 70.5 Equivalent Gates

NOTE: Information on typical parametric values can be found in Chapter 2 of the Motorola High–Speed CMOS Data Book (DL129/D).
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.
