Description

Patented message mode

The MT89L85 Enhanced Digital Switch device is an

upgraded 3-volt version of the MT8985 Digital Switch.

It is pin compatible with the MT8985 and retains all of

the MT8985's functionality. The enhanced digital

switch is designed for switching PCM-encoded voice or

data, under microprocessor control, in digital

Non-multiplexed microprocessor interface

Available in PLCC-44 and SSOP-48 packages

Pin compatible with MT8985 device

Low power consumption

exchanges,

PBXs

and

any

ST-BUS/MVIP

environment. It provides simultaneous connections for

up to 256 64 kb/s channels. Each of the eight serial

inputs and outputs consist of 32 64 kbit/s channels

multiplexed to form a 2048 kbit/s stream. As the main

function in switching applications, the device provides

per-channel selection between variable or constant

throughput delays. The constant throughput delay

feature allows grouped channels such as ISDN H0 to

be switched through the device maintaining its

sequence integrity. The MT89L85 is ideal for medium

sized mixed voice/data switch and voice processing

applications.
