DESCRIPTION...
The SP333 is a monolithic device that supports both MacintoshTM 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.
