High–Performance Silicon–Gate CMOS
The MC54/74HCT574A is identical in pinout to the LS574. This device
may be used as a level converter for interfacing TTL or NMOS outputs to
High Speed CMOS inputs.
Data meeting the setup time is clocked 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 HCT574A is identical in function to the HCT374A but has the
flip–flop inputs on the opposite side of the package from the outputs to
facilitate PC board layout.
• Output Drive Capability: 15 LSTTL Loads
• TTL NMOS Compatible Input Levels
• Outputs Directly Interface to CMOS, NMOS and TTL
• Operating Voltage Range: 4.5 to 5.5 V
• Low Input Current: 1.0 µA
• In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
• Chip Complexity: 286 FETs or 71.5 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.
