Here's my take on it: Микросхема представляют собой преобразователь двоичного кода в десятичный. Корпус типа 421ю50-1. Назначение выводов: 3 - вход гашения; 5, 13, 15 - вспомогательные входы; 7, 21 - вход 1 разряда; 9, 19 - вход 8 разряда; 11 - вход 4 разряда; 17 - вход 2 разряда; 23 - вход запятой; 27 - выход Q0; 24, 25 - общие; 29 - выход запятой; 31 - выход Q9; 33 - выход Q8; 35 - выход Q7; 37 - выход Q6; 39 - выход Q5; 41 - выход Q4; 43 - выход Q3; 45 - выход Q2; 47 - выход Q1; 49, 50 - напряжение питания. Chip is a binary-decimal converter, package type 421Y50-1. 49,50: supply voltage 24,25: common (ground) 7,21: 1 input 17: 2 input 11: 4 input 9, 19: 8 input 3: blanking input 5, 13, 15: auxiliary (mode?) inputs 23: comma input 27: output Q0 47: output Q1 45: output Q2 43: output Q3 41: output Q4 39: output Q5 37: output Q6 35: output Q7 33: output Q8 31: output Q9 29: comma output - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
