A response control input is provided for the receiver. A resistor or a resistor and a bias voltage can be connected between the response control input and ground to provide noise filtering. The driver used is similar to the SN75188. The receiver used is similar to the SN75189A. The SN75155 is characterized for operation from 0°C to 70°C. logic symbol† DA RA RTC logic diagram 2 7 DY VCC + DA 5 6 VCC – 3 RESP RY 1 8 2 4 GND † This symbol is in accordance with ANSI/IEEE Std 91-1984 and IEC Publication 617-12 RA RTC 5 6 7 DY Reference Regulator 3 RY Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
