What the 7405PC is and where it fits
The 7405PC is a hex inverter gate with six independent inverter circuits, each with an open-collector output.
Lifecycle and compliance
This part is RoHS non-compliant. Verify your assembly house accepts leaded finishes.
Open-collector output — what it means for your circuit
The open-collector output on each of the six inverters can sink current or go high-impedance. An external pull-up resistor is required for a logic-high level.
