The MAX14914, MAX14914A and MAX14914B are the family of high-side/push-pull drivers that operate as both an industrial digital output (DO) and an industrial digital input (DI). The MAX14914 family features full IEC 61131-2 compliance in both their DO and DI modes of operation. The high-side switch current is resistor settable from 135mA (min) to 1.3A (min). The high-side driver’s on-resistance is 120mΩ (typ) at 125°C ambient temperature. Optional push-pull operation allows driving of cables and fast discharge of load capacitance. The output voltage is monitored and indicated through the
The MAX14914 family complies with Type 1, Type 2, or Type 3 input characteristics when configured for DI operation.
The MAX14914A is a low-DOI-leakage version of MAX14914, designed to work together with the MAX22000 Industrial Configurable Analog IO device. The MAX14914B features a high-side switch overcurrent indication.
