CD4541 programmable timer
The CD4541 is a CMOS programmable timer IC that provides timing functions for various applications. It features a precision oscillator and a programmable counter capable of generating accurate time delays or frequencies. The CD4541 can operate in monostable (one-shot), astable (free-running), or bistable (flip-flop) modes, making it versatile for different timing requirements in digital circuits. It offers high noise immunity, low power consumption, and is suitable for a wide range of supply voltages.
