Drawing 7 mA from the supply, the part's quiescent load is low enough that it can share a 5 V rail with a microcontroller without pushing the regulator into dropout, even in always-on sensor modules where every milliamp counts. ## 54-SSOP exposed pad — layout and thermal considerations Housed in a 54-SSOP (0.295\", 7.50 mm width) with an exposed pad, the package is also listed as 54-SOIC-EP in the supplier device code — same footprint, same thermal pad. The 0.025-inch (0.635 mm) pitch requires a 2-layer board with via-in-pad or a 4-layer stack for fan-out — a 1-layer board cannot route all 54 signals without violating clearance rules. ## Active lifecycle and compliance — no obsolescence pressure This is a stable BOM line for designs already in production. No franchised allocation signal on this part today.","metaTitle":"MC33794DHR2 Sensor Interface, 7 mA, -40°C to 85°C, 54-SSOP","metaDescription":"Active NXP MC33794DHR2 Sensor Interface with ISO9141 output, 7 mA supply, -40°C to 85°C. 54-SSOP exposed pad.
