MC145028DW General Description

The MC145028DW is a versatile and reliable dual tone multi-frequency (DTMF) receiver IC, designed to meet the demanding requirements of telephone systems, paging systems, and various communications applications. With two independent DTMF tone decoders capable of detecting all 16 DTMF tones used in standard telephony, this IC delivers high-quality performance. Its low power consumption of 7mA and the ability to operate from a single 5V power supply make it a cost-effective solution for energy-efficient designs. Moreover, the IC's built-in hysteresis effectively eliminates false triggering caused by input signal noise or distortion. Additionally, the inclusion of a power-down mode further minimizes power consumption when the IC is not in use. The MC145028DW also features an open-collector output that can drive a LED to indicate DTMF detection, adding to its convenience and usability. Housed in a 16-pin SOIC package, this IC is easy to integrate into various electronic designs, making it an ideal choice for applications that require reliable DTMF reception
