Procurement Notes
Verify the specific ordering suffix 'PW' confirms the TSSOP-14 package type required for your design. Confirm that the 'Q1' suffix aligns with your automotive qualification requirements. Ensure the selected variant matches the specified thermal and electrical ratings for your intended operating environment.
Selection Notes
Select this component when designing circuits requiring six independent inverters with open-drain capabilities. It is suitable for applications needing TTL compatibility and robust automotive reliability. Consider the TSSOP-14 package constraints and ensure adequate thermal management for high-current burst operations.
Part Context
This part belongs to the SN74ACT05-Q1 family of automotive hex inverters. It shares functional characteristics with other members of the series but differs in packaging options such as WQFN variants. The PW suffix specifically denotes the Thin-Shrink Small-Outline Package (TSSOP) configuration.

FAQ
What is the function of the open-drain outputs?
Open-drain outputs can only drive the output low. In the high logical state, they enter a high-impedance state, requiring an external pull-up resistor to define the high voltage level.
How should unused inputs be handled?
Unused inputs must not be left floating. They should be terminated to either VCC or ground using a pull-up or pull-down resistor to prevent oscillations and excessive power consumption.
