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
