SN74LVC02A的产品描述：
The SN54LVC02A quadruple 2-input positive- NOR gate is designed for 2.7-V to 3.6-V VCC operation and the SN74LVC02A quadruple 2-input positive-NOR gate is designed for 1.65-V to 3.6-V VCC operation.
The ’LVC02A devices perform the Boolean function Y = A + B or Y = A • B in positive logic.
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment.
The SN54LVC02A is characterized for operation over the full military temperature range of –55°C to 125°C. The SN74LVC02A is characterized for operation from –40°C to 85°C.
