IDT74LVC16827A
DESCRIPTION:
This 20-bit buffer is built using advanced dual metal CMOS technology.
The LVC16827A provides high-performance bus interface buffering for
wide data/address paths or buses carrying parity. Two pairs of NAND-ed
output enable controls offer maximum control flexibility and are organized
to operate the device as two 10-bit buffers or one 20-bit buffer. Flow-through
organization of signal pins simplifies layout. All inputs are designed with
hysteresis for improved noise margin.
The LVC16827A buffer is ideally suited for driving high capacitance loads
and low impedance backplanes.
All pins 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 LVC16827A has been designed with a ±24mA output driver. The
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
