MAX14906 Industrial Digital Output/Digital Input Analog Devices Inc. MAX14906 Industrial Digital Output/Digital Input is an IEC 61131-2 compliant, high-speed, four-channel industrial digital output, digital input device. The device can be configured on a per-channel basis as a high-side (HS) switch, push-pull (PP) driver, or a Type 1 and 3, or Type 2 digital input. The ADI MAX14906 is specified for operation with a supply voltage up to 40V and is tolerant to 65V. The high-side switch current limiting is settable from 130mA to 1.2A with the option of 2x load inrush current. The high-side driver on-resistance is 120mΩ (Typ.) at 25°C ambient temperature. The optional push-pull operation allows high-speed driving of cables and fast discharge of load capacitance. For digital input operation, current sinks for 2.3mA (Type 1 and 3) or 7mA (Type 2) are provided.
