DRIVE FEATURES:
APPLICATIONS:
鈥?Balanced Output Drivers: 鹵12mA
鈥?Low switching noise
The LVC162244A 16-bit buffer/driver is built using advanced dual metal
CMOS technology. The LVC162244A 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 LVC162244A has series resistors in the device output structure
which will significantly reduce line noise when used with light loads. This
driver has been developed to drive 鹵12mA at the designated threshold
levels.
