MC74HC573A/D
MC74HC573A
Octal 3-State Noninverting
Transparent Latch
HighPerformance SiliconGate CMOS
The MC74HC573A is identical in pinout to the LS573. The devices
are compatible with standard CMOS outputs; with pullup resistors,
they are compatible with LSTTL outputs.
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 time becomes latched.
The HC573A is identical in function to the HC373A but has the data
inputs on the opposite side of the package from the outputs to facilitate
PC board layout.
Output Drive Capability: 15 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS and TTL
Operating Voltage Range: 2.0 to 6.0 V
Low Input Current: 1.0
A
In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
Chip Complexity: 218 FETs or 54.5 Equivalent Gates

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 highimpedance cir-
cuit. 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.
