ST1480AB ST1480AC 3.3 V powered, 15 kV ESD protected, up to 12 Mbps true RS-485/RS-422 transceiver Datasheet - production data Description The ST1480Ax is 15 kV ESD protected, 3.3 V low power transceiver for RS-485 and RS-422 communications. The device contains one driver and one receiver in half duplex configuration. The ST1480Ax transmits and receives at a guaranteed data rate of at least 12 Mbps. 62 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 Features thermal shutdown circuitry that places the driver outputs into a high-impedance state. ESD protection 15 kV human body model The ST1480Ax input has a true fail-safe feature that guarantees a logic high output if both inputs 8 kV IEC 1000-4-2 contact discharge are open circuit, shorted together or in the Operates from a single 3.3 V supply - no presence of a termination with no signal on the charge pump required bus. Interoperable with 5 V logic 1 A low current shutdown mode max Guaranteed 12 Mbps data rate -7 to 12 common mode input voltage range Half duplex versions available Industry standard 75176 pinout Current limiting and thermal shutdown for driver overload protection Guaranteed high receiver output state for floating, shorted or terminated inputs with no signal present Allows up to 64 transceivers on the bus Table 1.
