SIT3088EESA [SIT]

Key Features

1. Wide 3.0V to 5.5V supply voltage
The device can work with both 3.3V and 5V logic systems, making it convenient for MCU, DSP, and industrial controller designs.

2. Half-duplex RS-485 / RS-422 communication
SIT3088E integrates one driver and one receiver, suitable for two-wire RS-485 bus communication and many industrial serial communication networks.

3. Up to 14Mbps data transmission
The device supports high-speed communication up to 14Mbps, which is useful for applications requiring faster data exchange over a differential bus.

4. High ESD protection on bus pins
The bus pins provide over 15kV HBM ESD protection, improving reliability in industrial environments where electrostatic discharge and cable-related disturbances are common.

5. ±15V bus fault tolerance
The bus withstand voltage range reaches ±15V, helping protect the transceiver against abnormal bus voltage conditions.

6. Supports up to 256 nodes on one bus
With 1/8 unit-load input impedance, SIT3088E allows up to 256 transceivers to be connected on the same communication bus, which is useful for multi-node industrial networks.

7. Built-in protection functions
The chip includes fail-safe protection, over-temperature protection, current limiting, and over-voltage protection, improving system-level reliability.

8. Strong anti-noise capability
As a differential RS-485 transceiver with integrated transient voltage suppression features, it is suitable for electrically noisy environments such as factories, power systems, and automation equipment.
