It operates from a single 3.0V to 5.5V supply and generates RS-232 compliant output levels (+\/-5.5V typical) using an internal dual charge pump. The first charge pump doubles VCC (via C1+\/-) to produce V+ (approximately 2xVCC), and the second inverts V+ (via C2+\/-) to produce V- (approximately -2xVCC). Four external 0.1uF capacitors are required for the charge pump. The driver outputs swing between +5.5V and -5.5V at 3.3V supply, exceeding the RS-232 minimum of +\/-5V. The receivers accept RS-232 input levels as low as +\/-3V and convert them to TTL\/CMOS logic levels (0-3.3V). The EN pin enables the receiver outputs (active HIGH), and the SHDN pin shuts down the charge pump and all outputs (active LOW, reducing Iq to 1uA). The Q1 suffix indicates AEC-Q100 Grade 0 qualification (-40C to +125C), making it suitable for automotive diagnostic ports (OBD-II). The device supports data rates up to 250kbps, sufficient for standard RS-232 serial communication. ESD protection on the bus pins is +\/-15kV HBM. The typical supply current is 1mA in active mode.","pin_description":"
