SN74LVC02APWE4

Inverter Gates Overview

The SN74LVC02APWE4 is a quadruple 2-input positive-NOR gate from the Texas Instruments LVC logic family. It operates within a supply voltage range of 1.65V to 3.6V and supports input voltages up to 5.5V, enabling translation between 3.3V and 5V systems. The device provides four independent NOR gates in a 14-pin TSSOP package. Electrical characteristics include a maximum propagation delay of 4.4ns at 3.3V and output drive currents of ±24mA at 3V. It functions reliably across temperature ranges of -40°C to 85°C and -40°C to 125°C.

Inverter Gates Procurement Notes

Verify that the ordering suffix 'E4' corresponds to the specific lead finish and RoHS compliance status required for your assembly process. Confirm the package type matches the footprint on your PCB design. Ensure the operating temperature range meets your environmental specifications. Check the latest datasheet revision for any updates to thermal or electrical parameters before finalizing procurement.

Inverter Gates Selection Notes

Select this component when a quadruple 2-input NOR function is required in low-voltage applications. The 5.5V tolerant inputs make it suitable for interfacing with legacy 5V logic without additional level shifters. Consider the TSSOP-14 package for surface-mount designs requiring moderate pin density. Evaluate the propagation delay and output current capabilities against your circuit's speed and load requirements.
