ACT 4489 DUAL TRANSCEIVER

FOR MIL-STD-1553/1760

CIRCUIT TECHNOLOGY

Features

• +5 / ±12 Volt Supply Operation

• Low Power Dissipation

General Description

The

Aeroflex

Circuit

• Small Size & Light Weight

Technology ACT 4489 is a next

generation monolithic transceiver

design

compliance to MIL-STD-1553A/B

and 1760 requirements in a small

package

• Dual Transceivers Saves Space & Cost

• Outstanding MIL-STD-1553 performance

• Radiation Hard Dielectric Isolation Monolithic

Construction for Severe Environments

• Superior High Frequency Line Transient and Input

Ripple Rejection

which

provides

full

with

low

power

consumption.

The ACT 4489 series performs

the front-end analog function of

inputting and outputting data

through

transformer to the

• Input and Output TTL Compatible Design

• Processed and Screened to MIL-STD-883 Specs

• MIL-PRF-38534 Compliant Devices Available

MIL-STD-1553 data bus.

Design of this transceiver reflects

particular attention to active filter

performance. This results in low bit

and word error rate with superior

waveform purity and minimal zero

crossover

distortion.

Efficient

transmitter electrical and thermal

design provides low internal power

dissipation and heat rise at high as

well as low duty cycles.

Each channel of the dual

transceiver is completely separate

Hence, each channel may be
