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
