The TIL920 has one channel in a 4-pin package, the TIL921 has two channels in an 8-pin package, and the TIL922 has four channels in a 16-pin package. The standard devices, TIL920, TIL921, and TIL922, are tested for a current-transfer ratio of 20% minimum. Devices selected for a current-transfer ratio of 50% and 100% minimum are designated with the suffix A and B respectively. mechanical data 4,80 (0.189) 4,19 (0.165) TIL920 1 10,2 (0.400) 9,2 (0.362) TIL921 1 21,1 (0.831) 18,5 (0.728) TIL922 C L C L 1 7,62 (0.300) T.P.
