SEMICONDUCTOR TECHNICAL DATA
Programmable Timer
with 16 stages selectable by a binary code. Provisions for an on–chip RC
oscillator or an external clock are provided. An on–chip monostable circuit
incorporating a pulse–type output has been included. By selecting the
appropriate counter stage in conjunction with the appropriate input clock
frequency, a variety of timing can be achieved.
* Maximum Ratings are those values beyond which damage to the device may occur.
