MC14490P Description

Short technical summary and product information.

The MC14490P from ON Semiconductor is a versatile integrated circuit designed for eliminating extraneous level changes when interfacing with mechanical contacts. It effectively removes contact bounce on both the make and break of a contact closure, providing a clean digital signal. This device can be utilized as a digital integrator, system synchronizer, or delay line.

 

The MC14490P features diode protection on all inputs and internal pullups on all data inputs. It supports an internal R-C oscillator or an external clock source, with a Schmitt trigger on the clock input for enhanced stability. The device operates over a wide supply voltage range of 3.0V to 18V and an ambient temperature range of -55°C to +125°C.

 

Available in PDIP-16 and SOIC-16 packages, the MC14490P is suitable for various applications requiring reliable digital signal conditioning from mechanical switches. Its design allows for cascadable configurations to achieve longer time delays.
