(TOP VIEW)

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.

20 19

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.
