MC145436ADW

The MC145436ADW is a CMOS DTMF receiver from Motorola designed to decode dual-tone multi-frequency signals used in telephone keypads and remote control systems. By converting audio tones into digital outputs, this IC allows microcontrollers and control logic to interpret dialed commands quickly and accurately. It integrates the necessary filtering and detection stages internally, reducing external component count and simplifying overall circuit design. This makes it well-suited for telecom equipment, access control systems, IVR platforms, and embedded devices that require dependable tone recognition. The SOP-16 surface-mount package supports compact layouts and efficient automated assembly. Florida Circuit sources genuine Motorola components and inspects each lot to ensure quality and consistency. When building or maintaining communication products that rely on clear tone decoding, the MC145436ADW offers a proven, easy-to-integrate solution that balances performance, reliability, and design simplicity.
