Products Detail

The SP481, SP483, and SP485 are half-duplex transceivers that meet the requirements of RS-485 and RS-422. Fabricated with Sipex proprietary BiCMOS process, all three products require a fraction of the power of older bipolar designs. The SP481 and SP485 support data rates up to 5Mbps, while the SP483 is slew-rate limited for low EMI and supports up to 250kbps. The SP481 and SP483 feature a low-power shutdown mode. The devices have driver and receiver enable controls. The receivers have a wide common mode range of -7V to +12V and a fail-safe feature ensuring a HIGH output when inputs are unconnected. The drivers maintain differential output levels even under worst-case loading.
