INFORMATION
EXTENDED COMMERCIAL TEMPERATURE RANGE
DESCRIPTION:
The LVC534A device features 3-state outputs designed specifically for
driving highly capacitive or relatively low-impedance loads. This device
is particularly suitable for implementing buffer registers, input-output (I/O)
ports, bidirectional bus drivers, and working registers.
On the positive transition of the clock (CLK) input, the
Q outputs are set
to the logic levels set up at the data (D) inputs.
A buffered output-enable (
OE) input can be used to place 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
drive provide the capability to drive bus lines without interface or pullup
components.
OE does not affect internal operations of the latch. Old data
can be retained or new data can be entered while the outputs are in the
high-impedance state.
All pins can be driven from either 3.3V or 5V devices. This feature allows
the use of this device as a translator in a mixed 3.3V/5V supply system.
