Wide-supply OR gate for mixed-voltage logic
The SN74LVC2G32DCTR is a dual 2-input OR gate from the 74LVC family, operating from 1.65 V to 5.5 V. This supply range lets it bridge 1.8 V, 2.5 V, and 3.3 V logic domains on the same board without a separate level translator — the input thresholds scale with VCC, so a 1.8 V signal is recognized as high when the gate runs at 3.3 V. Propagation delay is 3.2 ns at 5 V with a 50 pF load, fast enough for clock gating or control logic in most microcontroller and DSP interfaces. The 32 mA symmetric output drive can fan out to multiple CMOS inputs or switch a low-current LED directly.
Temperature grade and package fit
Rated for -40°C to +125°C, the gate suits industrial enclosures, outdoor telecom, and under-hood automotive auxiliary logic where the ambient exceeds the commercial 85°C ceiling. The SM8 package (8-LSSOP or 8-MSOP, 2.80 mm body width) fits tight PCB layouts — the 0.65 mm pin pitch demands careful fan-out but keeps the footprint under 15 mm². Quiescent current is 10 µA max across the temperature range, so the gate adds negligible drain in battery-backed or always-on circuits.
Sourcing and lifecycle
The SN74LVC2G32DCTR carries an active lifecycle status — no end-of-life notice, no last-time-buy window. It is qualified ROHS3 compliant. Sourced through independent distribution; availability and current pricing are confirmed at RFQ against the BOM quantity.
