MT90840 Product details

Description

Pin # 84 3 100 43 Name DS/RD Description MT90840 Data Strobe/Read (Input).In Motorola multiplexed-bus mode this pin is DS, an active high input which works with CS to enable read and write operation.In Intel/ National multiplexed-bus mode this pin is RD, an active low input which enables a read-cycle and configures the data bus lines (AD0-AD7) as outputs.Address Strobe / Address Latch Enable (Input).Falling edge is used to sample address into the Address Latch circuit.Chip Select (Input).

Features

Time slot interchange function between eight pairs of ST-BUS/GCI/MVIP ™ streams (512 channels) and parallel data port Programmable data rates on the parallel port (19.44, 16.384, or 6.480 Mbyte/s) Programmable data rates on the serial port (2.048 Mbps, 4.096 Mbps or 8.192 Mbps) Supports star and point-to-point connections, and unidirectional or bidirectional ring topologies for distributed systems Input-to-output bypass function on the parallel data port for use in add/drop.
