Description

The MSC1202Y2RHHTG4 is a Bi-CMOS display driver for 1/2-duty vacuum fluorescent display tube. It is designed to display frequencies for audio systems used in automobile applications and various information. The MSC1202Y2RHHTG4 also has the ability to accept keyboard entry, allowing for front panel functions to be carried out using only this IC. It features a data parity check function and self-check functions for easy inspection and failure detection. With serial interfacing, only two signal lines are required for connection with a microcontroller.
