● Guaranteed high receiver output state for floating, shorted or terminated inputs with no signal present
● Allows up to 64 transceivers on the bus
DESCRIPTION
All transmitter outputs and receiver inputs are protected to ±15 kV using Human Body Model. Driver is short-circuit current limited and is protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance state. The ST1480Ax input has a true fail-safe feature that guarantees a logic high output if both inputs are open circuit, shorted together or in the presence of a termination with no signal on the bus.
