IDT74LVC2244A
DESCRIPTION:
This octal buffer/driver is built using advanced dual metal CMOS
technology. The LVC2244A device is organized as two 4-bit line drivers
with separate output-enable (
OE
) inputs. When
OE
is low, the device
passes data fromthe A inputs to the Y outputs. When
OE
is high, the outputs
are in the high-impedance state.
To ensure the high-impedance state during power up or power down,
OE
should be tied to Vcc through a pullup resistor; the mnimumvalue of
the resistor is determned by the current-sinking capability of the driver.
The LVC2244A has series resistors in the device output structure which
will significantly reduce line noise when used with light loads. This driver
has been designed to drive ±12mA at the designated threshold levels.
Inputs can be driven fromeither 3.3V or 5V devices. This feature allows
the use of this device as a translator in a mxed 3.3V/5V systemenviron-
ment.
