from 7V to 65V. The internal LDO output can  
supply up to 25mA of current in addition to powering the  
basic MAX22193 requirements. This LDO can be used  
to power digital isolators and other field-side circuits.  
Alternatively, the MAX22193 can be powered from an  
The MAX22193 translates four 24V industrial digital  
inputs to four CMOS-logic-compatible, parallel outputs.  
Propagation delay from input-to-output is less than  
300ns for all four channels. Current-limiter on each  
digital input greatly reduces power dissipation compared  
to traditional resistive input. The accuracy of these  
current-limiters minimizes power dissipation while  
ensures compliance with the IEC 61131-2 standard. A  
current-setting resistor allows the MAX22193 to be  
configured for Type 1, Type 2 or Type 3 digital inputs.  
Additionally, the MAX22193 has energyless field-side  
LED drivers to meet the indicator light requirement of  
IEC 61131-2 with no additional power dissipation.  
external 3.0V to 5.5V supply at V  
.

The MAX22193 includes an open-drain READY output  
that asserts high to indicate the MAX22193 is functional.  
If the V  
field-side supply voltage is too low, or a fault  
DD24  
in the current-setting resistor is detected, or the device  
reaches an over-temperature condition, the READY  
signal is set to high-impedance.
