Applications
Features

ESD protection 15 kV human body model 8 kV IEC 1000-4-2 contact discharge Operate from a single 3.3 V supply - no charge pump required Interoperable with 5 V logic 1 �A low current shutdown mode max. Guaranteed 20 Mbps data rate 12 V common mode input voltage range Half duplex versions available Industry standard 75176 pinout Current limiting and thermal shutdown for driver overload protection

Description

The ST4485EBDR device 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 ST4485EBDR transmits and receives at a guaranteed data rate of at least 20 Mbps. All transmitter outputs and receiver inputs are protected 15 kV using "Human Body Model". The 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.

Pin 1 2 Symbol RO RE Name and function Receiver output. by 200 mV, RO will be high; by 200 mV, RO will be low. Receiver output enable. RO is enabled when RE is low; RO is high impedance when RE is high. RE is high and DE is low, the device will enter a low power shutdown mode. Driver output enable. The driver outputs are enabled by bringing DE high. They are high impedance when DE is low. RE is high DE is low, the device will enter a low-power shutdown mode. If the driver outputs are enabled, the part functions as line driver, while they are high impedance, it functions as line receivers RE is low. Driver input. A low on DI forces output A low and output B high. Similarly, a high on DI forces output A high and output B low. Ground Non-inverting receiver input and non-inverting driver output Inverting receiver input and inverting driver output Supply voltage: VCC 3.6 V
