HA12187FP数据手册集成电路（IC）的驱动器接收器收发器规格书PDF

描述 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.

特性 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 VFunctions
• Two-input OR circuit
• Input comparator circuit
• Current output driver circuit
• Receiver input comparator circuit
• Receiver output circuit
• Standby circuit
