Description

The HEF4541BP is a Programmable Timer with a 16-stage binary counter, an integrated oscillator to be used with external timing components, an automatic power-on reset and output control logic. The frequency of the oscillator is determined by the external components RTC and CTC within the frequency range 1Hz to 100kHz. This oscillator may be replaced by an external clock signal at input RS, the timer advances on the positive-going transition of RS. A low on the auto reset input (AR) and a low on the master reset input (MR) enables the Internal power-ON reset. A high level at input MR resets the counter independent on all other inputs. Resetting disables the oscillator to provide no active power dissipation.
Fully static operation
Standardized symmetrical output characteristics
Complies with JEDEC standard JESD 13-B
