HA12187FP - Bus Interface Driver/Receiver

General 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.

Two-input OR circuit Input comparator circuit Current output driver circuit Receiver input c

Key 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 vo.
