MAX481E Overview
Key Specifications
Package: SOIC
Mount Type: Surface Mount
Pins: 8
Operating Voltage: 5 V
Description
The MAX481E, MAX483E, MAX485E, MAX487E– MAX491E, and MAX1487E are low-power transceivers for RS-485 and RS-422 communications in harsh environments. Each driver output and receiver input is protected against ±15kV electro-static discharge (ESD) shocks, without latchup.
Key Features
- The driver slew rates of the MAX481E, MAX485E, MAX490E, MAX491E, and MAX1487E are not limited, allowing them to transmit up to 2.5Mbps
- These transceivers draw as little as 120µA supply current when unloaded or when fully loaded with disabled drivers (see Selector Guide)
- Additionally, the MAX481E, MAX483E, and MAX487E have a low-current shutdown mode in which they consume only 0.5µA
- All parts operate from a single +5V supply
- The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit
