MM1192

The MinebeaMitsumi MM1192 is a transceiver integrated circuit designed for efficient communication over a two-wire bus line. This IC incorporates essential external functions into a single package, enabling the creation of a bus line using twisted pair wires or similar configurations. It features a built-in input signal synthesis circuit for communication, an output stage capable of driving the bus line, and a 5V power supply circuit that operates from a single power source.

The MM1192 utilizes the AMI signal waveform for both transmitting and receiving units, providing strong noise immunity. This allows for reliable mutual communication even when connected to various equipment such as telephone, security, audio/video, and air conditioning systems over extended bus lines. Key specifications include 2 data lines, an AMI signal waveform, a typical data signaling rate of 9.6 kbps, an upper limit of 100 kbps, and a maximum transmission distance of 1200 meters with up to 256 nodes.

This transceiver IC operates within an ambient temperature range of -20°C to 75°C and requires a VCC operating voltage between 4.5V and 5.5V. It is housed in a SOP-16B package, suitable for surface mounting.
