3.3V CMOS 16-BIT
BUFFER/DRIVER
WITH 3-STATE OUTPUTS,
5 VOLT TOLERANT I/O
IDT74LVC16244A
DESCRIPTION:
The LVC16244A 16-bit buffer/driver is built using advanced dual metal
CMOS technology. The LVC16244A is designed specifically to improve
both the performance and density of 3-state memory address drivers, clock
drivers, and bus-oriented receivers and transmitters. The device can be
used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. This device
provides true outputs and symmetrical active-low output-enable (OE)
inputs.
All pins of this 16-bit buffer/driver can be driven from either 3.3V or 5V
devices. This feature allows the use of the device as a translator in a mixed
3.3V/5V supply system.
The LVC16244A has been designed with a ±24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
