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.

Functions

• Two-input OR circuit

• Input comparator circuit (3.3 V and 5.0 V available)

• Current output driver circuit

• Receiver input comparator circuit

• Receiver output circuit (Open-collector output)

• Standby circuit

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
