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.

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.

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.
