INFORMATION
EXTENDED COMMERCIAL TEMPERATURE RANGE
DESCRIPTION:
The LVC533A octal transparent D-type latch is built using advanced dual
metal CMOS technology. The device features 3-state outputs designed
specifically for driving highly capacitive or relatively low-impedance loads,
and is particularly suitable for implementing buffer registers, input-output (I/
O) ports, bidirectional bus drivers, and working registers.
While the latch-enable (LE) input is high, the Q outputs follow the data
(D) inputs. When LE is taken low, the Q outputs are latched at the logic levels
at the 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.
OEdoesnotaffecttheinternaloperationsofthelatch.Olddata
can be retained or new data can be entered while the outputs are in the
high-impedance state.
The LVC533A has been designed with a ±24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
Inputs 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 system environ-
ment.
