74AHCT1G86GW,165

Overview

The Nexperia 74AHCT1G86GW,165 is a single 2-input EXCLUSIVE-OR gate housed in a TSSOP5 (SOT353-1) plastic thin shrink small outline package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features overvoltage tolerant inputs up to 5.5 V, enabling use as a translator in mixed voltage environments. Static characteristics include low input leakage current and CMOS low power dissipation. Dynamic performance specifies propagation delays with maximum values of 9.0 ns at CL = 15 pF and 10.5 ns at CL = 50 pF under recommended operating conditions.
