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
