DESCRIPTION…
The SP333 is a monolithic device that supports both Macintosh™ and PC serial interfaces. RS-232 mode offers three (3) RS-232 drivers and five (5) RS-232 receivers. Mac mode includes a differential driver and a single-ended inverting driver. Receivers in Mac mode include one differential receiver, one non-inverting single-ended receiver and one inverting single-ended receiver. An on-chip charge pump allows +5V-only operation, and a low power Shutdown mode makes the SP333 ideal for battery powered applications. The interface mode can be changed at any time by a mode select pin.
