SEMICONDUCTOR TECHNICAL DATA
Octal 3-State Inverting
Transparent Latch
High–Performance Silicon–Gate CMOS
The MC54/74HC563A is identical in pinout to the LS563. The device
inputs are compatible with standard CMOS outputs; with pullup resistors,
they are compatible with LSTTL outputs.
This device is identical in function to the HC533A but has the Data Inputs
on the opposite side of the package from the outputs to facilitate PC board
layout.
These latches appear transparent to data (i.e., the outputs change
asynchronously) when Latch Enable is high. The data appears at the outputs
in inverted form. When Latch Enable goes low, data meeting the setup and
hold time 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 HC573A is the noninverting version of this function.
Output Drive Capability: 15 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 2 to 6 V
Low Input Current: 1 µA
High Noise Immunity Characteristic of CMOS Devices
In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
Chip Complexity: 202 FETs or 50.5 Equivalent Gates

* Maximum Ratings are those values beyond which damage to the device may occur.
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 cir-
cuit. For proper operation, Vin and
v vVout should be constrained to the
range GND (Vin or Vout) 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.
Functional operation should be restricted to the Recommended Operating Conditions.
