Overview
ST1480AB ST1480AC 3.
3 V powered, 15 kV ESD protected, up to 12 Mbps true RS-485/RS-422 transceiver Datasheet - production data 62 Features • ESD protection – ±15 kV human body model – ±8 kV IEC 1000-4-2 contact discharge • Operates from a single 3.
3 V supply - no charge pump required • Interoperable with 5 V logic • 1 µA 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 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.
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.
