12 8Q

These 8-bit D-type transparent 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.

(TOP VIEW)

While the latch-enable (LE) input is high, the Q

outputs follow the complements of 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 a 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 SN54ALS563B is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74ALS563B is characterized for operation from 0°C to 70°C.
