Overview
The Nexperia 74HCT4051BQ,115 is an 8-channel analog multiplexer/demultiplexer housed in a DHVQFN16 (SOT763-1) package. It operates with a VCC supply voltage range of 4.5 V to 5.5 V and supports dual supplies from -5 V to +5 V. The device features three digital select inputs (S0-S2), eight independent I/Os (Yn), a common I/O (Z), and an active-low enable input (E). Key electrical parameters include a maximum ON resistance of 180 Ω at VCC=4.5 V/VEE=0 V, propagation delay up to 12 ns, turn-on time up to 55 ns, and turn-off time up to 45 ns. It functions within an ambient temperature range of -40 °C to +125 °C.
Feature Summary
- Provides single-pole octal-throw switching for routing analog or digital signals between one common terminal and eight independent terminals.
- Features logic level translation capabilities to interface 5 V logic systems with ±5 V analog signal ranges.
- Includes built-in ESD protection exceeding 2000 V for human body model and 1000 V for charged device model standards.
Applications
- Analog multiplexing and demultiplexing
- Digital multiplexing and demultiplexing
- Signal gating

Selection Notes
Select this component when a CMOS 8:1 analog switch is required with HCT logic compatibility. Ensure the design accommodates the DHVQFN16 thermal pad requirements and that the operating voltage stays within the specified 4.5 V to 5.5 V range for optimal performance.
Part Context
This part belongs to the 74HCT4051 family, which shares pinout and functional compatibility with the 74HC4051 series. The primary distinction lies in the logic input thresholds, where the HCT variant is optimized for 5 V CMOS operation while maintaining compatibility with TTL logic levels.
Replacement Considerations
The 74HCT4051BQ,115 is functionally interchangeable with other 74HCT4051 variants in different packages, such as the 74HCT4051PW (TSSOP16) or 74HCT4051D (SO16), provided the physical footprint allows for package substitution.
FAQ
What is the state of the switches when the Enable (E) input is HIGH?
When the Enable (E) input is HIGH, all internal switches are turned off, placing the outputs in a high-impedance state regardless of the select input values.
How does the device handle input voltages exceeding VCC?
The inputs include clamp diodes, which allow the use of current-limiting resistors to safely interface inputs to voltages in excess of VCC without damaging the device.
What is the typical 'break before make' behavior of this switch?
The device exhibits typical 'break before make' switching characteristics, ensuring that the previous connection is断开 before the new connection is established during channel transitions.
