DESCRIPTION
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 HA12187FP Block Diagram VCC 7 S1 1 S2 3 + – Driver output (current) 6 BUS (+) 8 BIAS 5 BUS (–) R 2 Receiver output – COM + 4 Rev.2, Jun. 1999, page 2 of 23 HA12187FP Pin Functions Pin No.
