Package and footprint — 24-TVSOP
The 24-TVSOP package measures 0.173" body width, 4.40 mm. Surface mount. ROHS3 compliant.
Temperature range and environment
Rated for -40°C to 85°C, the SN74CBTD3861DGVR covers industrial environments — outdoor telecom cabinets, factory-floor controllers, and automotive cabin (non-engine bay). The 85°C upper limit excludes under-hood or high-temp industrial processes. If the ambient near the switch exceeds 85°C, look at the 74CBTD family's extended-temperature variants or a different bus-switch series.
