MT8885AN1

MT8885AN1 Description

The MT8885AN1 is a DTMF (Dual-Tone Multi-Frequency) transceiver integrated circuit designed for telecommunications applications. Manufactured by Microchip Technology, this obsolete component is housed in a 24-pin surface mount package and is available in a tube format. It operates within a supply voltage range of 4.75V to 5.25V and draws a supply current of 7mA. The MT8885AN1 is REACH unaffected and RoHS3 compliant, ensuring it meets environmental and safety standards. It has a moisture sensitivity level (MSL) of 3, which means it can be stored for up to 168 hours before reflow soldering.
