If anyone has them, could they fill in the tables below : Fairchild 9311 (4 bit -> 16 line decoder?) 1 : O/ 2 : 1/ 3 : 2/ 4 : 3/ 5 : 4/ 6 : 5/ 7 : 6/ 8 : 7/ 9 : 8/ 10 : 9/ 11 :10/ 12 : Gnd 13 : 11/ 14 : 12/ 15 : 13/ 16 : 14/ 17 : 15/ 18 : E0/ 19 : E1/ 20 : A3 21 : A2 22 : A1 23 : A0 24 : Vcc Fairchild 93L14 (latch?) 1 : ENABLE/ 2 : SET 0/ 3 : D0 4 : D1 5 : SET 2/ 6 : D2 7 : D3 8 : Gnd 9 : MASTER RESET/ 10 : Q3 11 : SET 3/ 12 : Q2 13 : Q1 14 : SET 1/ 15 : Q0 16 : Vcc Signetics 8273 (10 bit serial-in, parallel out shift register) 1 : Q6 2 : Q7 3 : Q8 4 : Q9 5 : Q10 6 : Clk/ 1 7 : Clk 2 8 : Gnd 9 : Clr/ 10 : Serial In 11 : Q1 12 : Q2 13 : Q3 14 : Q4 15 : Q5 16 : Vcc Note: The unused Clock performs the INHIBIT function. --------------------------------------------- Thanks in advance for any help -tony --------------------------------------------- You are MOST welcome; delighted to have an opportunity to repay you for the many times you've helped us. Let me know if you need detailed tech data; I have the Fairchild Data and Application Books and the Signetics Data Book. I even have a fair bit of 9300 ICs, but alas, no 9311s and only the regular power 9314. Probably no 8273s but I can have a look. Good luck & thanks again for all YOUR help! mike
