MAX487EEPA+

The MAX487EEPA+ is a ±15KV ESD protected, slew rate limited, low power RS485/RS422 transceiver in 8 pin DIP package. This device is used as a low power transceiver for RS485 and RS422 communications in harsh environments. The driver output and receiver input is protected against ±15KV electro static discharge (ESD) shocks without latch-up. The reduced slew rate driver minimizes EMI and reduces reflections caused by improperly terminated cables, thus allowing error free data transmission up to 250Kbps. 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. It features fail-safe circuitry which has a logic high receiver output when the receiver input is open.

• Supply voltage range from 4.75V to 5.25V

• Designed for half duplex communication
• Low current shutdown mode consume 0.5μA current
• Features receiver/driver enable function
• Quiescent current is 120μA
• Quarter unit load receiver input impedance
• Allows up to 128 transceivers on the bus
