Overview
The Nexperia 74HC05BQ,115 is a hex inverter with open-drain outputs belonging to the HC logic family. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device utilizes a DHVQFN14 package (SOT762-1) measuring 2.5 mm by 3.0 mm with a height of 0.85 mm. Propagation delays vary between 9 ns and 27 ns depending on the supply voltage.
Feature Summary
- Open-drain output architecture enables active-LOW wired-OR or active-HIGH wired-AND configurations when connected to other open-drain outputs.
- High ESD protection capabilities exceeding 2000 V for Human Body Model and 1000 V for Charged Device Model.
- Robust latch-up performance exceeding 100 mA per JESD 78 Class II level A standards.
Applications
- Implementing active-LOW wired-OR logic functions
- Implementing active-HIGH wired-AND logic functions
- General-purpose signal inversion in CMOS circuits
Procurement Notes
Verify that the specific ordering suffix matches the required thermal enhanced very thin quad flat package variant. Confirm the temperature grade aligns with the design requirements, as the datasheet specifies operation up to +125 °C. Ensure pull-up resistors are included in the circuit design, as the open-drain outputs require them to perform correctly.
Selection Notes
Select this component when a hex inverter with open-drain outputs is required for wired-logic applications. The HC logic family provides standard CMOS input levels suitable for general digital interfacing. Consider the DHVQFN14 package dimensions if PCB space is limited and surface-mount technology is preferred over leaded packages.
Part Context
This part belongs to the 74HC05 series of hex inverters manufactured by Nexperia. The 'BQ' designation specifically identifies the DHVQFN14 package version (SOT762-1), distinguishing it from SO14 or TSSOP14 variants. The '115' suffix indicates the standard reel packaging configuration provided by the manufacturer.

FAQ
Can the outputs be directly connected together?
Yes, the open-drain outputs can be connected to other open-drain outputs to implement active-LOW wired-OR or active-HIGH wired-AND functions.
Is a ground pin solderable requirement?
No, the exposed pad is not a ground pin. There is no electrical or mechanical requirement to solder it; if soldered, the land should remain floating or connected to GND.
