The MAX14914, MAX14914A, and MAX14914B are a family of high-side/push-pull drivers that operate as both industrial digital outputs (DO) and industrial digital inputs (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 an ambient temperature of 125°C. Optional push-pull operation allows driving of cables and fast discharge of load capacitance. The output voltage is monitored and indicated through the DOI_LVL pin for safety applications.
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 the MAX14914, specifically designed to work together with the MAX22000 Industrial Configurable Analog IO device. The MAX14914B features a high-side switch overcurrent indication.
