The low level complementary driver is a push-pull driver with level shifting circuitry which accepts a low level input (output level - VBE). The self-inversion feature eliminates the need for dual-phase or phase-splitting predrivers, and the total emitter-follower configuration produces minimal delay and offers high input impedance. The no-load power dissipation is very low in the Up level state and low in the Down level state. Transient response of the circuit is excellent because the Ft of the indirectly driven transistor T3 is higher than that of T1 or T2.
