HA12187FP Overview
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 parator circuit Current output driver circuit Receiver input parator circuit Receiver output circuit Standby circuit.
HA12187FP Key Features
- Supports two data inputs (Pins 1 and 3 are the input pins)
- parators with hysteresis characteristics were adopted for the inputs
- Current drive output drivers adopted (Output current: 3.8 mA typical)
- parators with hysteresis characteristics were adopted for the receivers
- Wide receiver mon-mode input operating range (mon-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
- Driver output (current) 6
