MT88L85AN1

Our MT88L85AN1 product represents a breakthrough in CMOS integrated circuits specifically crafted for tone/pulse telephone dialers. It boasts a 16-digit priority auto-dialer with a built-in slotted interrupt, allowing for unparalleled flexibility to cater to various user requirements. This exceptional device excels at decoding dual-tone multi-frequency (DTMF) tones and enables users to effortlessly select any of the 16 priority numbers for automatic dialing. With a touch-tone detector for DTMF signaling and a transient oscillator for pulse signaling, the MT88L85AN1 ensures precise and reliable performance. Additionally, its register-based control offers versatile programming options, while the integrated EEPROM memory simplifies the storage and retrieval of frequently dialed numbers without the need for an external memory device. Boasting a power consumption of less than 100mW and a power-down mode for further energy savings, this device sets new benchmarks for efficiency. Operating within a voltage range of 2.5V to 5.5V, the MT88L85AN1 is housed in a 24-pin DIP package, making it suitable for a wide range of applications in telecommunication systems
