ARX1555

ARX1555 is a kind of data terminal bit processor which operates at an internally generated system clock rate of 1 MHz.There are some features as follows.First,ARX1555 performs digital functions common to MIL-STD-1553 and MACAIR.The second is manchester encode and decode.Then is broadcast.Next is mode code.The fifth is address.The sixth is time out.The seventh is three state parallel I/O.The seventh is wrap-around self test.The eighth is internal clock oscillator.The ninth is low power option.The tenth is interchangeable with BUS 64100 and CT 1555.The last one is screened per MIL-STD-883.

What comes next is about the absolute maximum ratings of ARX1555.The supply voltage is +7.0 V for both standard and low power.The logic input voltage is from -0.3 to +5.5 V for standard version and from -0.5 to V_CC+0.5 V for low power version.The logic input current is from -20 to +4 mA for standard version and ±1.0 mA for low power version.The clock output current (PIN 18) is 15 mA for both standard and low power version.The clock in (PIN 17) is from -0.3 to V_CC+0.3 V for both standard and low power version.The storage temperature range is from -65 to +150 for both standard and low power version.The operating case temperature range is from -55 to +125 for both standard and low power version.

The following is about the electrical characteristics of ARX1555.The minimum V_IH1 (logic "1" input voltage (except D0-D15 and A0-A4)) is 2.0 V for both standard and low power version.The minimum V_IH2 (logic "1" input voltage for D0-D15 and A0-A4) is 2.0 V for standard version and is 3.5 V for low power version.The maximum V_IL (logic "0" input voltage) is 0.8 V for both standard and low power version.The minimum V_OH (logic "1" output voltage) is 2.5 V for both standard and low power version.The maximum V_OL (logic "0" output voltage) is 0.4 V.
