Description

DATASHEET MC14490 . Hex Contact Bounce. Eliminator. The MC14490 is constructed with complementary MOS enhancement mode devices, and is used for the elimination Debounce filters such as the MC14490 Hex Contact Bounce Eliminator manufactured by ON. Semiconductor are often used to address encoder contact bounce. signals controlled by SW3 and SW4 are debounced by MC14490 (U12) before connecting to an LatticeECP2 I/O pin.
