The HEF4051BT,653 from Nexperia is an 8-channel analog multiplexer/demultiplexer built around a single-pole, eight-throw SP8T bidirectional analog switch. It can select one of eight independent signals to a common terminal or distribute a common signal to one of eight channels, supporting both analog and digital multiplexing applications.
Three digital select inputs, S1, S2, and S3, determine which of the Y0-to-Y7 channels is connected to the common Z terminal. A separate enable input E controls all switches; when E is HIGH, all eight channels are switched off.
The HEF4051B operates over a recommended 3.0V-to-15.0V supply range and provides specified characteristics at 5V, 10V, and 15V. The separate VEE supply allows the analog switch section to accommodate bipolar signals when the supply rails are configured appropriately.
At 25°C with VSS=VEE=0V and a 200μA switch current, typical peak ON resistance is approximately 350Ω at 5V, 80Ω at 10V, and 60Ω at 15V. Maximum peak ON resistance at 15V is 175Ω.
For analog signal handling, Nexperia specifies a typical −3dB frequency response of 70MHz at 15V. Typical total harmonic distortion is approximately 0.04% at 10V, while OFF-state isolation is approximately −50dB at 1MHz and 10V under the specified test conditions.
CMOS construction provides low static power consumption. At 25°C and with no output load, maximum supply current is specified at approximately 5μA at 5V, 10μA at 10V, and 20μA at 15V. The control inputs also incorporate clamp diodes and provide high noise immunity.
The device is specified for operation from −40°C to +125°C. Its absolute maximum VDD rating is 18V; however, normal circuit designs should remain within the recommended 3V-to-15V operating range.
HEF4051BT uses a 16-lead SO16 / SOT109-1 surface-mount package with an approximately 9.9mm × 3.9mm body, 1.27mm lead pitch, and maximum package height of approximately 1.75mm. The exact HEF4051BT,653 ordering code, 933372940653, is currently listed by Nexperia as Active.
The ,653 suffix is associated with Nexperia’s SOT109-1 reel packaging. Official packing information lists a 330mm / 13-inch reel, 16mm carrier tape, and 2,500-piece standard packing quantity for this packing configuration.
