SCD8510 Rev D

GENERAL DESCRIPTION

Aeroflex’s ACT8510 is a radiation tolerant, 64 channel multiplexer MCM (multi-chip module) with

electrostatic discharge (ESD) protection on all channel inputs.

The ACT8510 has been specifically designed to meet exposure to radiation environments. It is available in a

96 lead High Temperature Co-Fired Ceramic (HTCC) Quad Flatpack (CQFP). It is guaranteed operational

from -55°C to +125°C. Available screened in accordance with MIL-PRF-38534, the ACT8510 is ideal for

demanding military and space applications.

ORGANIZATION AND APPLICATION

The ACT8510 consists of six 16 channel multiplexers arranged as shown in the Block Diagram. The

ACT8510 design is inherently radiation tolerant.

A SECTION

separately. Each block connects the addressed channel to two outputs, "Output" and "Current".

This

technique enables selecting and reading a remote resistive sensor without the multiplexer resistance being

part of the measurement. For grounded sensors, this is done by passing current to the sensor by means of the

"Current" pin and reading the resultant voltage (proportional to the sensor resistance) at the "Output" pin.

B SECTION

separately. Each block connects the addressed channel to one output. By paralleling the channel inputs and

enables, this section can be converted to act like one of the 16 channel blocks of the A section.
