MIL-STD-1553A&B, Macair A3818,

A4905, A5232 and A5690 Specs

General Description

The Aeroflex Circuit Technology

ACT4418D is a new generation

monolithic transceivers which provide

full compliance with Macair and MIL-

• ±12 Volt Power Supply Operation

STD-1553 data bus requirements

while providing variable amplitude

• Voltage source output for higher bus

drive power

control.

The ACT4418D performs the front-

end analog function of inputting and

outputting data through a transformer

to a MIL-STD-1553 or Macair data

bus. The ACT4418D can be consid-

ered a "Universal" Transceiver in that

it is compatible with MIL-STD-1553A,

B, Macair A-3818, A-4905, A-5232

and A-5690.

• Molded Plug-in package

• Monolithic construction using linear

ASICs

• Variable TX Amplitude

Design of these transceivers

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. The ACT4418D

active filter design has additional high

frequency roll-off to provide the

required Macair low harmonic
