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
