Description

Low power consumption: typical 15mW

Pin compatible with the MT8980DP

This VLSI CMOS device is designed for switching

PCM-encoded voice or data, under microprocessor

control, in a modern digital exchange, PBX or

Central Ofﬁce. It provides simultaneous connections

for up to 256 64 kbit/s channels. Each of the eight

serial inputs and outputs consist of 32 64 kbit/s

channels multiplexed to form a 2048 kbit/s ST-BUS

In addition, the MT89L80 provides

microprocessor read and write access to individual

ST-BUS channels.
