The MC74HCT573A is identical in pinout to the LS573. This device may
be used as a level converter for interfacing TTL or NMOS outputs to
High–Speed CMOS inputs.
These latches appear transparent to data (i.e., the outputs change
asynchronously) when Latch Enable is high. When Latch Enable goes low,
data meeting the setup and hold times becomes latched.
The Output Enable input does not affect the state of the latches, but when
Output Enable is high, all device outputs are forced to the high–impedance
state. Thus, data may be latched even when the outputs are not enabled.
The HCT573A is identical in function to the HCT373A but has the Data
Inputs on the opposite side of the package from the outputs to facilitate PC
board layout.
The HCT573A is the noninverting version of the HC563A.
• Output Drive Capability: 15 LSTTL Loads

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
should be constrained to the
out
range GND v (Vin or V
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.
