Présentation
Description
Each multivibrator in the CD74HC123PWR can be independently controlled, with external resistors and capacitors setting the pulse width. It includes input clamping diodes, allowing for simple interfacing to TTL logic levels, and Schmitt-trigger action on the inputs enhances noise immunity, ensuring reliable operation in noisy environments.
The device is available in a TSSOP package (PWR suffix), making it compact and suitable for applications where space is a concern. Its wide range of applications includes pulse stretching, delay timing, pulse generation, and timing applications in various electronic circuits.
