NTE1478
Integrated Circuit
Solenoid Driver & Signal Sensing Circuit
Description:
The NTE1478 is an integrated circuit in a 10鈥揕ead SIP type package that detects the stopping of a
rotary signal and drives a plunger. It is designed for use in auto鈥搑everse and auto鈥揺ject car stereo
applications and can be used as a solenoid driver in many other control circuits.
Features:
