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
