HA12187FP
Bus Interface Driver/Receiver IC
ADE-207-174A (Z) 2nd Edition Jun. 1999 Description
The HA12187FP was 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 * Current output driver circuit * Receiver input comparator circuit * Receiver output circuit * Standby circuit
Features
* Supports two data inputs (Pins 1 and 3 are the input pins) * Comparators with hysteresis characteristics were adopted for the inputs * Current drive output drivers adopted (Output current: 3.8 mA typical) * Comparators with hysteresis characteristics were adopted for the receivers * Wide receiver common-mode input operating range (Common-mode input operating range: 0 to 5 V typical) * The driver output and the receiver input can withstand high voltages (Maximum rating: 18 V) * Standby function (The IC enters standby mode when pin 8 goes low) * Operating power-supply voltage range: 5 V 0.5 V
