Texas Instruments CD4016BPW

Overview

CD4016BPW from Texas Instruments is a CMOS quad bilateral switch IC designed for analog and digital signal routing in mixed-signal systems. It supports ±10V peak-to-peak analog signals or 20V digital switching, features 280Ω typical on-state resistance at 15V, <0.5% THD at 1kHz, and 40MHz bandwidth - enabling precise low-distortion signal gating in audio multiplexers and data acquisition front-ends.

For engineers reviewing the CD4016BPW datasheet, CD4016BPW pinout, CD4016BPW application, or CD4016BPW equivalent, key selection criteria include its matched on-resistance (≤10Ω variation), ultra-low off-state leakage (100pA typ.), high off-state impedance (>10¹² Ω), crosstalk rejection (−50dB at 0.9MHz), and operation across −55°C to +125°C industrial temperature range.

Technical Context

The CD4016BPW integrates four independent bilateral transmission gates, each controlled by a single logic-level input that simultaneously biases complementary p- and n-channel MOSFETs. Its symmetrical conduction path enables bidirectional analog signal flow with minimal voltage-dependent on-resistance variation over the full ±10V input range.

Each switch exhibits matched r_ON (Δr_ON ≤ 5Ω at V_DD = 15V), low feedthrough capacitance (0.2pF), and high isolation (65dB output-voltage ratio), making it suitable for precision sample-and-hold circuits, chopper-stabilized amplifiers, and digitally controlled gain/impedance networks where channel-to-channel consistency is critical.

FAQ

What is the maximum signal voltage swing supported by the CD4016BPW?

The CD4016BPW supports up to ±10V peak-to-peak analog signals or 20V digital signals, constrained by the V_DD−V_SS supply range of 3V to 18V. For example, with V_DD = 15V and V_SS = 0V, the signal path handles 0V to 15V; with V_DD = +7.5V and V_SS = −7.5V, it supports ±7.5V symmetric swing. The CD4016BPW datasheet specifies absolute maximum ratings of V_S/V_D = V_SS−0.5V to V_DD+0.5V.

Does the CD4016BPW require external pull-up or pull-down resistors on its control inputs?

No, the CD4016BPW does not require external pull-up or pull-down resistors on its control inputs (pins 3, 5, 12, 11). Its CMOS inputs exhibit extremely high impedance (10¹² Ω typical), and logic thresholds are defined relative to V_DD/V_SS: V_IL ≤ 0.7V (max) and V_IH ≥ 3.5V (min) at V_DD = 5V. Direct connection to microcontroller GPIO or logic gates suffices. The CD4016BPW operates reliably with clean digital drive without external biasing.

Can the CD4016BPW be used in a single-supply configuration?

Yes, the CD4016BPW supports single-supply operation with V_SS tied to ground and V_DD set between 3V and 18V. In this mode, signal inputs/outputs swing from 0V to V_DD, and control inputs accept 0V (OFF) and V_DD (ON). For instance, at V_DD = 12V, the CD4016BPW passes 0–12V analog signals with 280Ω r_ON and <0.5% THD - ideal for PLC I/O modules and industrial DAC output switching.

How does the CD4016BPW compare to the CD4066B in terms of on-resistance matching?

The CD4016BPW provides tighter on-resistance matching than the CD4066B: Δr_ON ≤ 5Ω (typ.) across switches at V_DD = 15V, versus ≤15Ω for CD4066B under identical conditions. This 3× improvement stems from optimized process trimming and layout symmetry in the CD4016B design. For applications like precision multiplexed sensor arrays or balanced modulators where channel gain tracking is critical, the CD4016BPW delivers superior consistency compared to CD4066B variants.

Is the CD4016BPW RoHS-compliant and lead-free?

Yes, the CD4016BPW is RoHS-compliant and lead-free, with NiPdAu lead finish and compliance verified per JEDEC J-STD-609. The "PW" package suffix denotes TSSOP-14 packaging meeting IPC/JEDEC standards for Pb-free assembly. Moisture sensitivity level is rated Level-1 (unlimited floor life at ≤30°C/60% RH), and peak reflow temperature is 260°C.
