MC14490 Hex Contact Bounce Eliminator IC (DIP-16 Package)
The MC14490 is a Hex Contact Bounce Eliminator IC housed in a DIP-16 package, designed to clean up noisy signals caused by contact bounce in switches or relays. This IC is used to ensure reliable, clean transitions in digital circuits, where switch contacts may generate multiple transitions (bounces) when they open or close. It is ideal for use in environments where mechanical switches are involved, such as keypad interfaces, relay systems, or microcontroller input processing. This IC operates by filtering out unwanted bounce signals and ensuring that only a single transition (either high or low) is recognized per switch activation. By removing bounce-induced errors, the MC14490 enhances the accuracy and stability of digital systems, particularly those using mechanical switches that are prone to contact bounce. The IC consists of six independent channels (hex configuration), meaning it can handle up to six switches simultaneously. It uses a simple and effective method to clean the input signals and outputs a debounced version of the signal, which can be safely fed into digital logic circuits without causing false triggering or missed events.
