ST ST4485EBDR

收发器RS422，RS48520Mbps

Overview

Guaranteed high receiver output state for floating inputs with no signal present Allow to 64 transceivers on the bus Wide operating temperature range: +105 �C

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
