description

These 8-bit latches feature three-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)

The eight latches are transparent D-type latches.

While the enable (C) is high the Q outputs will

follow the complements of data (D) inputs. When

the enable is taken low the output will be latched

at the inverses of the levels that were set up at the

D inputs.

20 19

A buffered output-control input can be used to

place the eight outputs in either a normal logic

9 10 11 12 13

state (high or low logic levels) or

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 the bus lines in a bus-organized system

without need for interface or pull-up components.

INPUTS

OUTPUT

The output control (OC) does not affect the

internal operation of the latches. Old data can be

retained or new data can be entered while the

outputs are in the high-impedance state.

ENABLE

The SN54ALS563A 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.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
