SAK140 Datasheet - Philips

I II I SAK140 REVOLUTION COUNTER The SAK140 is a monolithic integrated circuit intended for use as a revolution counter in motor cars.

It contains a stabilization circuit and a monostable multivibrator which converts the circuit input pulses into output current pulses of constant duration and amplitude.

This pulse duration is determined by an external R -C network; by proper choice of R and C, the circuit can be easily adapted to any milliammeter.

Together with the internal stabilization circ
