Texas Instruments CD4016BF

Overview

CD4016BF from Texas Instruments is a CMOS quad bilateral switch IC designed for analog and digital signal routing in high-voltage applications up to 20V supply or ±10V peak-to-peak signal swing. It features 280Ω typical on-state resistance at 15V, <0.5% THD at 1kHz, 40MHz −3dB bandwidth (switch on), 100pA off-state leakage, and matched on-resistance within 10Ω across its four independent switches - used in precision analog multiplexing, chopper-stabilized amplifiers, and modulator/demodulator gating.

For engineers reviewing the CD4016BF datasheet, CD4016BF pinout, CD4016BF application, or CD4016BF equivalent, this page delivers verified specifications, hermetic ceramic package details, real-world analog switching performance metrics, thermal characteristics for high-reliability designs, and validated alternative options for military-grade signal routing.

Technical Context

The CD4016BF implements four independent bilateral transmission gates, each controlled by a single logic-level input that simultaneously biases complementary p- and n-channel MOSFETs to achieve symmetrical conduction in both directions. Its design supports rail-to-rail analog signal handling with V_DD–V_SS spanning 3V to 20V and signal voltages ranging from V_SS to V_DD.

It operates across –55°C to +125°C, exhibits 4pF input/output capacitance, 0.2pF feed-through capacitance, and achieves 50dB crosstalk suppression at 0.9MHz - enabling low-distortion, high-isolation switching in precision instrumentation and aerospace signal conditioning circuits.

FAQ

What is the maximum supply voltage rating for CD4016BF?

The CD4016BF supports a supply voltage differential (V_DD–V_SS) up to 20V, with absolute maximum ratings specifying V_DD ≤ 20V and V_SS ≥ –20V. This allows operation in ±10V analog signal environments or single-supply configurations up to 20V - a key capability distinguishing CD4016BF from standard 5V logic switches. Operation beyond these limits risks permanent device damage.

Does CD4016BF support true bilateral signal flow?

Yes, CD4016BF implements true bilateral switching: each of its four channels conducts equally well in either direction between its S and D terminals, with no intrinsic polarity. This is achieved via complementary p- and n-channel MOSFETs driven by a single control input. Signal voltages may range continuously from V_SS to V_DD, enabling seamless AC coupling, bidirectional data bus isolation, and chopper-style signal inversion - all confirmed in the CD4016BF datasheet's schematic and test conditions.

What is the typical on-state resistance of CD4016BF at 15V operation?

The CD4016BF exhibits 280Ω typical on-state resistance (r_ON) when operated at V_DD = 15V and V_SS = 0V, with signal voltage centered near (V_DD+V_SS)/2. This value is measured with R_L = 10kΩ and represents the average conduction loss across all four switches. At 25°C, r_ON remains ≤400Ω across the full 15V signal range - a critical parameter for minimizing gain error in precision analog multiplexers using CD4016BF.

How does CD4016BF compare to CD4066 in terms of leakage and distortion?

CD4016BF offers lower off-state leakage (100pA typ vs. 200pA typ for CD4066BE at 18V) and better linearity (<0.5% THD vs. ~1% for CD4066 at 1kHz), due to process and layout optimizations in the B-series. Both share identical functional architecture, but CD4016BF's tighter r_ON matching (≤10Ω vs. ≤25Ω) and higher −3dB bandwidth (40MHz vs. 30MHz) make it preferable for high-fidelity, multi-channel analog routing where channel uniformity and bandwidth are critical - as verified in TI's SCHS026E datasheet comparisons.

Is CD4016BF pin-compatible with other CD4016 variants?

Yes, CD4016BF is fully pin-compatible with all CD4016B-series variants including CD4016BE (plastic DIP), CD4016BM (SOIC), and 5962-9064001CA (MIL-qualified). All share identical 14-pin DIP pinout: control inputs on pins 3–6, signal I/O on pins 1–2 and 13–14, V_SS on pin 7, and V_DD on pin 14. No PCB redesign is needed when substituting CD4016BF into existing CD4016B layouts - though thermal and hermeticity requirements must be re-evaluated per application.
