74LVCE1G02SE-7

Inverter Gates Overview

The Diodes Incorporated 74LVCE1G02SE-7 is a single 2-input positive NOR gate in the LVCE logic series, housed in an SOT-353 package. It operates within a supply voltage range of 1.4V to 5.5V and supports partial power-down applications via IOFF circuitry. The device features inputs tolerant to 5.5V for mixed-voltage environments. Electrical characteristics include a propagation delay of up to 3.6ns at 5V with 50pF load, low-level output current of 32mA, and high-level output current of -32mA. Operating temperature ranges from -40°C to +85°C.

Inverter Gates Procurement Notes

Verify the specific ordering suffix SE corresponds to the SOT-353 package configuration required for your design. Confirm that the -7 suffix indicates tape and reel packaging quantities as specified in the manufacturer's ordering information. Ensure input pins are held at VCC or Ground if unused to maintain stable operation within the recommended operating conditions.

Inverter Gates Selection Notes

Select this component for designs requiring a single NOR gate with mixed-voltage tolerance and partial power-down capabilities. The LVCE series offers speed improvements over LVC at lower voltages. Consider the SOT-353 package constraints regarding thermal resistance and pad layout recommendations provided in the datasheet for proper PCB integration.
