ACT4489

The ACT4489(Aeroflex Circuit Technology) performs the front-end analog function of inputting and outputting data through a transformer to the MIL-STD-1553 data bus which is a next generation monolithic transceiver design which provides full compliance to MIL-STD-1553A/B and 1760 requirements in a small package with low power consumption. The ACT4489 is designed 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.

The features of ACT4489 can be summarized as (1)+5/±12 volt supply operation; (2)low power dissipation; (3)small size & light weight; (4)outstanding MIL-STD-1553 performance; (5)radiation hard dielectric isolation monolithic construction for severe environments; (6)superior high frequency line transient and input ripple rejection; (7)input and output TTL compatible design; (8)processed and screened to MIL-STD-883 specs; (9)MIL-PRF-38534 compliant devices available.

The absolute maximum ratings of ACT4489 are (1)operating case temperature: -55°C to +125°C; (2)storage case temperature -65°C to +150°C; (3)power supply voltage: VCC -0.3V to +18V, VEE +0.3 V to -18 V, VL -0.3 V to +7.0 V; (4)logic input voltage: -0.3 V to +5.5 V; (5)receiver differential input: ±40 VP-P; (6)receiver input voltage (common mode): ±10V; (7)driver peak output current: 300 mA; (8)total package power dissipation over the full operating case temperature rise: 2.5 Watts; (9)maximum junction to case temperature: 10°C; (10)thermal resistance - junction to case: 4°C/W.
