Used in 15-stctge counter. Circuit is conventional, but to economize on current, only first three stages operate with relatively high collector currents; for these, RI and R2 +R3 are 5,600 ohms and transistors are 2N496. Subsequent stages use OC201 transistors and increasingly higher values of collector load, up to 22,000 ohms for 8th stage.-J.
