The skill of European engineers in Motorola's
So starts a story in Electronics Weekly's edition of October 1st 1975.
The story continues:
The circuit is being used in a 27-chanel ultrasonic remote control unit. The LSI CMOS transmitter unit, and a companion NMOS receiver, together form a remote control system suitable fro television and other applications.
When none of the push-buttons are actually pressed, the IC automatically reverts to a shut-down state in which power consumption is reduced to such a low level it was found unnecessary to provide an on/off switch.
In fact, it has been argued that the tiny current drain actually extends the life of the battery beyond the normal shelf life.
Thanks, moreclick, I'll try to do more, but two posts a day is keeping me quite busy as it is.
