The wide single-supply range from 3 V to 20 V covers 5 V, 12 V, and 15 V logic and analog rails without an extra regulator. ## On-resistance and bandwidth — what they mean for signal integrity Maximum on-resistance is 240 Ohm, with channel-to-channel matching held to 5 Ohm. In a precision analog path, the 240 Ohm Ron adds a voltage divider with the load impedance — if the downstream load is 10 kOhm, the gain error is about 2.3 %. The 5 Ohm matching keeps the error consistent across channels. The -3 dB bandwidth is 20 MHz, so the mux passes audio, 10 MHz IF signals, and moderate-speed data without significant roll-off. Off-channel leakage is limited to 100 nA max, and the off-channel capacitance is 0.2 pF — both help maintain signal isolation at higher frequencies. ## Dual-supply flexibility for bipolar analog rails The CD4051BNSRE4 also accepts dual supplies from ±2.5 V to ±9 V, letting it switch bipolar analog signals around ground. This is useful in audio crosspoint switches, data acquisition front-ends, and industrial sensor multiplexing where the signal swings below the single-supply ground reference.","metaTitle":"CD4051BNSRE4 CMOS Analog Multiplexer, 8:1, 240 Ohm","metaDescription":"Texas Instruments CD4051BNSRE4 8:1 analog multiplexer/demultiplexer. 240 Ohm max on-resistance, 20 MHz bandwidth, 3V to 20V single supply.
