Overview
The SN74LVC2G04DBVT, produced by Texas Instruments, is a dual inverter gate designed for operation over a wide voltage range of 1.65 V to 5.5 V. This device is part of the LVC (Low-Voltage CMOS) family and is known for its low power consumption and high-speed operation. The SN74LVC2G04 features two identical inverters, each capable of driving balanced outputs with up to 32 mA at 4.5 V. The device is also overvoltage tolerant, allowing input voltages up to 5.5 V, and supports partial-power-down mode operation, making it versatile for various applications.
