Caveats
Specs come from the Device Overview, A-5 General Specs and 13.0 Digital I/O pages; per-spec accuracy/noise pages (A-3-2) are not covered. The digital I/O page describes T-series devices generally (thresholds are 'typical'; exact per-device thresholds are in the specifications). T7 vs T7-Pro/OEM variants differ; values here are for T7 unless noted. LabVIEW support not verified from a fetched LabJack page, so no LabVIEW relation. Status 'current' reflects that the T7 is listed in the active datasheet. Audit: all values are LabJack-stated specifications (vendor docs), not independently measured. A-5 tables (supply current, temperature range) apply to the T-series generally with T7-specific rows where given; the -40 to 85 C operating range row is not T7-specific, and the datasheet notes accuracy specs are valid at room temperature only. USB supply current max 500 mA: exceeding it can trip current protection (A-5 note).

T7 digital I/O uses 3.3 V logic: outputs drive 0 or 3.3 V; inputs read 0 below a typical 0.9 V threshold and 1 above a typical 2.1 V threshold (the page refers to the specifications for per-device thresholds). Evidence: Documented

T-Series devices use 3.3V Logic. When set to output, the IO will be driven to 0 or 3.3V. ... If the voltage is below the low threshold (typically 0.9 V) the IO will report 0. If the voltage is above the high threshold (typically 2.1 V) the IO will report 1. ... All T-Series DIO are 5V Tolerant.
