The HEF4541BP from NXP Semiconductors is a versatile programmable timer IC. It integrates a 16-stage binary counter, an oscillator that can be set with external components (Rt and Ct) within a frequency range of 1 Hz to 100 kHz, and output control logic. The device supports selectable counter stages of 8, 10, 13, or 16, determined by address inputs A0 and A1.
This timer can function as a single transition timer or a frequency divider based on the mode select input. It includes an automatic power-on reset and a master reset input for flexible control. The HEF4541BP is available in various package types, including 14-lead DIP (plastic and ceramic) and 14-lead SO (plastic).
Key features include its programmable counter stages and adjustable oscillator frequency, making it suitable for various timing and frequency division tasks in electronic circuits.
