NE556N dual precision timing circuits 14 pin dil qty 2
These devices provide two independent timing circuits of the NE555, SA555, or SE555 type in each package. These circuits can be operated in the astable or the monostable mode with external resistor-capacitor (RC) timing control. The basic timing provided by the RC time constant can be controlled actively by modulating the bias of the control-voltage input. The threshold (THRES) and trigger (TRIG) levels normally are two-thirds and one-third, respectively, of VCC. These levels can be altered by using the control-voltage (CONT) terminal. When the trigger input falls below trigger level, the flip-flop is set and the output goes high. If the trigger input is above the trigger level and the threshold input is above the threshold level, the flip-flop is reset, and the output is low. The reset (RESET) input can override all other inputs and can be used to initiate a new timing cycle. When RESET goes low, the flip-flop is reset and the output goes low. When the output is low, a low-impedance path is provided between the discharge (DISCH) terminal and ground (GND).

The chip comes in an 14-Lead Plastic Dual In-line.
This is Bi-ploar, therefore it is NOT static-sensitive.
**FREE POSTAGE ON EACH ADDITIONAL IC**
All orders are fully compensated for.
You can order as many adapters as we have in stock from this listing and any other listing, yet still only pay for the cost of postage for the first adaptor. This is because the adaptors weight is almost negligible, and thus the increase in postage cost is very tiny compared to the combined value of all adapters ordered; basically we pay the additional cost!
**PLEASE NOTE THAT WE DO NOT POST TO ITALY, DUE TO THE HIGH VOLUME OF POST THAT 'GOES MISSING'**
