HA12240FP
Bus Interface Driver/Receiver IC
REJ03F0095-0100Z
Rev.1.0
Dec.01.2003
Description
The HA12240FP 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
