Description
The R2A11210SP is developed to be used as a bus interface driver/receiver IC in automotive audio equipment
controllers. It implements a two-wire serial bus.

Features
• Supports two data inputs (Pins 1 and 3 are the input pins)
• Comparators with hysteresis characteristics are adopted for the inputs (3.3 V and 5.0 V available)
• Current drive output drivers adopted (Output current: 3.8 mA typical)
• Comparators with hysteresis characteristics are adopted for the receivers
• Wide receiver common-mode input operating range (Common-mode input operating range: 0 to 5 V typical)
• The driver output /the receiver input (pins 5 and 6) can withstand high voltages (Maximum ratings of 18 V)
• Standby functions (standby mode when pin 8 becomes low level)
• Operating power-supply voltage range of 5 V ± 0.5 V
