MC74HCT573A
Octal 3-State Noninverting
Transparent Latch with
LSTTL Compatible Inputs
High−Performance Silicon−Gate CMOS
http://onsemi.com
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.

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
Vout should be constrained to the
range GND v (Vin or Vout) 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.

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of
these limits are exceeded, device functionality should not be assumed, damage may occur and
reliability may be affected.
