IDT74LVC573A
DESCRIPTION:
The LVC573A 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.
OE
does not affect the 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.
The LVC573A 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
environment.
Drive Features for LVC573A:
– High Output Drivers:
±24mA
– Reduced system switching noise
APPLICATIONS:
• 5V and 3.3V mixed voltage systems
• Data communication and telecommunication systems
