HEF4541B Description
The HEF4541B is a programmable timer which consists of a 16-stage binary counter, an integrated oscillator to be used with external timing ponents, an automatic power-on reset and output control logic. The frequency of the oscillator is determined by the external ponents Rt and Ct within the frequency range 1 Hz to 100 kHz. This oscillator may be replaced by an external clock signal at input RS, the timer advances...
