ACT 4453 / 4463
SINGLE SUPPLY TRANSCEIVERS
FOR MIL-STD-1553/1760
Features
• Single 5 Volt Supply Operation
CIRCUIT TECHNOLOGY
www.aeroflex.com/act1.htm
• Low Power Dissipation
General Description:
The Aeroflex Circuit Technology
ACT4453 / 4463 series are next
generation monolithic transceiver
• Small Size & Light Weight
• Dual Transceivers save Space & Cost
• Outstanding MIL-STD-1553 performance
designs
which
provides
full
compliance with MIL-STD-1553A/B
and 1760 requirements in the
smallest packages with low power
consumption and single power supply
operation.
• Processed and screened to Mil-STD-883
specs
• Radiation Hard Dielectric Isolation
Monolithic construction for Severe
Environments
The ACT4453
/
4463 series
performs the front-end analog
function of inputting and outputting
data through a transformer to the
MIL-STD-1553 data bus.
• Superior High Frequency Line Transient and
Input Ripple Rejection
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
• Input and Output TTL Compatible Design
• MIL-PRF-38534 Compliant Devices Available
• DESC SMD# 5962-89522
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
from the other and fully independent.
This includes power leads as well as
signal lines. Hence, each channel
may be connected to a different data
bus with no interaction.
