description
These 8-bit transparent D-type latches feature
3-state outputs designed specifically for driving
highly capacitive or relatively low-impedance
loads. They are particularly suitable for
implementing buffer registers, I/O ports,
bidirectional bus drivers, and working registers.
While the latch-enable (LE) input is high, the
Q
outputs follow the complements of the data (D)
inputs. When LE is taken low, the outputs are
latched at the inverses of the levels set up at the
D inputs.
A buffered output-enable (OE
) input places the
eight outputs in either a normal logic state (high or
low logic levels) or the high-impedance state. In
the high-impedance state, the outputs neither
load nor drive the bus lines significantly. The
high-impedance state and increased high logic
level provide the capability to drive bus lines
without interface or pullup components.
OE
does not affect internal operations of the latches. Old data can be retained or new data can be entered while
the outputs are in the high-impedance state.
The SN54HC563 is characterized for operation over the full military temperature range of –55°C to 125°C. The
SN74HC563 is characterized for operation from –40°C to 85°C.

‡
Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace
length of zero.
