Dual Precision Timer

These devices provide two independent Timing circuits of the NA555 NE555 SA555 or SE555 type in each package. These circuits CAN be operated in the astable or the monostable mode with external resistorcapacitor (RC) Timing control. The basic Timing provided by the RC time constant CAN be controlled actively by modulating the bias of the controlvoltage input. By Texas Instruments
