DSB3232 USB 32 channel Digital IO with mutiple voltage support.
The DSB3232 USB digital IO lines can be configured for input or output at the bit level supporting various logic family voltages. Those voltages included 1.8V, 2.5V 3.3V and 5V. Technicians wire the digital IO module using the on-board screw terminals. With the expanding number of logic level interface voltages, one of the challenges facing connecting devices to the USB bus is matching the required voltage levels and the DSB3232 meets those requirements.
