The 74HC4051D-Q100 from Nexperia is an automotive-qualified 8-channel analog multiplexer/demultiplexer based on a bidirectional single-pole octal-throw (SP8T) switch architecture. It includes eight independent analog I/O channels, Y0 through Y7, one common I/O terminal Z, and three digital select inputs for 8:1 multiplexing or 1:8 demultiplexing of analog or digital signals.
The HC version supports a 2.0V to 10.0V VCC-to-GND operating range, while the total VCC-to-VEE supply range is also 2.0V to 10.0V. With appropriate dual-supply operation, it can handle analog signals extending from -5V to +5V and includes logic-level translation for interfacing 5V digital logic with bipolar analog signals.
Typical ON resistance is 80Ω at 4.5V, 70Ω at 6V and 60Ω at 9V. Nexperia’s product parametrics list an ON-resistance parameter of 200Ω and an ON-resistance flatness of 20Ω, supporting low-loss analog signal routing.
The device incorporates typical break-before-make switching to reduce temporary overlap between channels during selection changes. Driving the enable input HIGH disconnects all channels, allowing the device to function as a signal gate. Input clamp diodes are also integrated for additional interface flexibility when used with appropriate current-limiting resistance.
The 74HC4051D-Q100 is qualified to AEC-Q100 Grade 1 and is specified over -40°C to +125°C for automotive applications. ESD protection exceeds 2000V HBM and 1000V CDM. Typical applications include automotive sensor multiplexing, analog signal selection, data-acquisition channel routing and digital signal gating.
The exact D-package version is supplied in a 16-pin SO16 (SOT109-1) package with an approximately 9.9 × 3.9mm body. The orderable 74HC4051D-Q100,118 version is currently listed as Active and uses a 13-inch tape-and-reel package containing 2500 devices.
