DESCRIPTION:
technology. This high-speed, low power transceiver is ideal for asynchro-
nous communication between two busses (A and B). The Direction and
Output Enable controls are designed to operate this device as either two
independent 8-bit transceivers or one 16-bit transceiver. The direction
control pin (DIR) controls the direction of data flow. The output enable pin
(OE) overrides the direction control and disables both ports. All inputs are
designed with hysteresis for improved noise margin.
the use of this device as a translator in a mixed 3.3V/5V supply system.
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
This 16-bit bus transceiver is built using advanced dual metal CMOS
All pins can be driven from either 3.3V or 5V devices. This feature allows
