The ’ACT563 are octal D-type transparent latches
with 3-state outputs. When the latch-enable (LE)
input is high, the Q outputs are set to the
complements of the data (D) inputs. When LE is
taken low, the Q outputs are latched at the inverse
logic 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.
9 10 11 12 13
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 SN54ACT563 is characterized for operation over the full military temperature range of –55°C to 125°C. The
SN74ACT563 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 maximum package power dissipation is calculated using a junction temperature of 150°C and a board trace length of 750 mils,
except for the N package, which has a trace length of zero.
