| TECHNICAL DATA Differential line receiver Microcircuit IL34C86 consists of four differential line receivers and is a microcircuit that meets international standards of data transmission RS-422, RS-423, and it is widely used in data transmission nets, particularly in a unit for local loop of ATS. Functions implemented This device carries out comparing inputs with low differential signal of 200mV and gives on output full signal with load carrying capacity of 6mA, and also has hysteresis to improve noise margin. IL34C86 IL34C86N Plastic DIP IL34C86D SOIC TA = -40C - 85C for all packages Truth table Enable L H H H input X VIDVTH (max) VIDVTH (max) Open * output Z H L H VID - difference of inputs A2-A1, or B2-B1, or C2-C1, or D2-D1. VTH - minimum differential input voltage. Open* - no signals delivered to inputs. 1 IL34C86 Pin Definitions and Functions Pin 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 Symbol A1 A2 A En A/C C C2 C1 GND D1 D2 D En B/D B B2 B1 VDD Functions Input of receiver A Input of receiver A Output of receiver A input of switching outputs of A and C receivers into the third state Output of receiver C 2 Input of receiver C 1 Input of receiver C General pin 1 Input of receiver D. 2 Input of receiver D.
