Overview
SP481/SP483/SP485 Low Power Half-Duplex RS-485 Transceivers FEATURES ■ +5V Only ■ Low Power BiCMOS ■ Driver/Receiver Enable ■ Slew Rate Limited Driver for Low EMI (SP483) ■ Low Power Shutdown Mode (SP481 and SP483) ■ RS-485 and RS-422 Drivers/Receivers RO 1 R 8 VCC RE 2 7B DE 3 6A DI 4 D SP485 5 GND Top View SP481, SP483, SP485 Pinout (Top View) DESCRIPTION The SP481, SP483, and the SP485 are a family of half-duplex transceivers that meet the requirements of RS-485 and RS-422.
Their BiCMOS design allows low power operation without sacrificing performance.
The SP481 and SP485 meet the requirements of RS-485 and RS-422 up to 5Mbps.
Additionally, the SP481 is equipped with a low power Shutdown mode.
The SP483 is internally slew rate limited to reduce EMI and can meet the requirements of RS-485 and RS-422 up to 250kbps.
The SP483 is also equipped with a low power Shutdown mode.
