Additional Details

The TC74HCU04AF is available in a SOP14 (Small Outline Package) and utilizes CMOS technology to achieve low power consumption and high noise immunity. The unbuffered outputs make it suitable for applications where sharp transitions are needed. It can operate with a wide supply voltage range (2V to 6V), providing flexibility in design. The input protection circuitry ensures that static discharge will not damage the device.

Its symmetrical output drive enables it to source and sink current equally, making it easier to interface with other devices in the circuit.
