Digital Input
Input voltage range
Power on: 0 V to 5 V
Power off: 0 V to 3.3 V
Do not leave a voltage above 3.3 V connected on the DIO line when the device
is not powered. This can cause long-term reliability issues.
Input voltage protection: ±20 V on two lines per port (maximum of five lines
for all ports) for up to 24 hours
Input high voltage: 2.3 V min
Input low voltage: 0.8 V max
Input leakage current
At 3.3 V: 0.8 mA max
At 5 V: 4.5 mA max
Digital Output
Output low voltage
4 mA: 0.7 V max
1 mA: 0.2 V max
Output high voltage: 3.6 V max
4 mA: 2.1 V min
1 mA: 2.8 V min
Maximum output current per line: ±4 mA
External Digital Trigger
Trigger source: TRIG input
Trigger mode: Software-selectable for rising or falling edge. Power on default is
rising edge.
Input high voltage: 2.3 V min
Input low voltage: 0.8 V max
Counter
Pin name: CTR
Number of counters: 1
Resolution: 32 bits
Counter type: Edge counter (rising)
Counter direction: Count up
Counter source: CTR
Input frequency: 5 MHz max
High pulse width: 100 ns min
Low pulse width: 100 ns min
LED Electrical Characteristics
Output low voltage
IOL = 8 mA: 0.4 V max
IOL = 18 mA: 1.2 V typ
External pull-up voltage: 5.25 V max
Maximum sinking current: 18 mA max
Memory
Data FIFO: 2,047 samples (4096 bytes)
Non-volatile memory
Up to 256 kB microcontroller integrated Flash
2 kB microcontroller integrated EEPROM
Power Requirements
From USB: 4.50 to 5.25 VDC
A typical bus-powered hub provides 100 mA on its USB lines. The USB-230 Series
devices do not work on bus-powered hubs.
Idle USB current: 165 mA
Maximum load USB current: <500 mA
The maximum power draw from all output terminals should be kept under
0.9 W to avoid overloading the USB port
Power Output
Output voltage: 5 V, ±3%
Maximum current: 150 mA
Overcurrent protection: 200 mA
Short circuit current: 50 mA
Overvoltage protection: ±20 V
