The driver circuit illustrated is an active collector type with tristate control capable of sinking 25 mA at 0.5 V due to the design of the transistor T6 device. Resistors R1 and R2 are chosen such that a maximum DC noise tolerance of + or - 600 mV is obtained with T/2/L inputs of +0.6 V and +2.4 V.
