ACT 4455 / 4459  
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  
ACT4455 / 4459 series are next  
generation monolithic transceiver  
• Small Size & Light Weight  
• Single Transceiver 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 ACT4455  
/
4459 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  
• DESC SMD# 5962-96741  
crossover  
distortion.  
Efficient  
transmitter electrical and thermal  
design provides low internal power  
dissipation and heat rise at high as  
well as low duty cycles.

The Transmitter section accepts  
bi-phase TTL data at the input and  
when coupled to the data bus with a  
1:2.5 ratio transformer, isolated on  
the data bus side with two 52.5 Ohm  
fault isolation resistors, and loaded by  
two 70 Ohm terminations, the data  
bus signal is typically 7.5 Volts P-P  
at A-A' (See Figure 5). When both  
DATA and DATA inputs are held low  
or high, the transmitter output  
becomes a high impedance and is  
“removed” from the line. In addition,
