Product details
Overview
CD4067BE from Texas Instruments is a 16-channel CMOS analog multiplexer/demultiplexer with binary address decoding, 125Ω typical ON resistance at VDD–VSS = 15V, ±10pA typical OFF channel leakage at 10V, and 0.2µW typical quiescent power dissipation - used for precision analog signal routing in data acquisition systems, sensor interface modules, and A/D converter front-ends.
For engineers reviewing the CD4067BE datasheet, CD4067BE pinout, CD4067BE application, or CD4067BE equivalent, key selection criteria include its 16:1 single-pole configuration, 3V–18V wide supply range, matched RON (5Ω typ), low THD (0.12% at 15V), and TSSOP-24/SOIC-24 package compatibility for mixed-signal PCB layouts.
Technical Context
The CD4067BE integrates a 4-bit binary decoder driving sixteen transmission-gate switches, enabling one-of-sixteen channel selection via inputs A/B/C/D plus an active-high INHIBIT that disables all paths. Its symmetrical bidirectional architecture supports both multiplexing (16 inputs → 1 common I/O) and demultiplexing (1 common I/O → 16 outputs) without polarity constraints.
Switch operation relies on complementary MOSFET pairs per channel, delivering constant RON across the full input signal range (VSS to VDD), minimal charge injection (<1pC), and high OFF isolation (>60dB at 1MHz). All digital control inputs feature CMOS protection networks and guaranteed VIH/VIL thresholds across 3V–18V operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel count | 16-channel single-pole analog switch array with 1 common I/O terminal |
| Supply voltage range | 3V to 18V - supports dual-supply (±5V, ±9V) or single-supply (5V, 12V, 15V) operation |
| ON resistance (RON) | 125Ω typ at VDD–VSS = 15V - enables <1% gain error in 12-bit ADC front-ends with 10kΩ source impedance |
| OFF leakage current | ±10pA typ at VDD–VSS = 10V - ensures <0.01% error in µA-level sensor current measurement |
| THD @ 1kHz | 0.12% max at VDD = 15V, 5Vpp signal - preserves fidelity in audio and instrumentation signal paths |
| Propagation delay | 7ns typ (tpd) at VDD = 15V - allows ≤10MHz address update rates in real-time scanning systems |
| Quiescent current | 0.2µW typ at VDD–VSS = 10V - enables battery-powered operation with negligible standby drain |
Pinout & Package
CD4067BE is supplied in a 24-pin plastic dual-in-line (PDIP) package (suffix E), with 0.3-inch body width and through-hole mounting. Pin spacing is 0.1 inch, compatible with standard DIP sockets and wave-solder processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 | Channel I/O terminals (Y0–Y15) | Bidirectional analog signal paths - each connects to common terminal when selected; no internal pull-up/down |
| 17 | COMMON OUT/IN | Shared analog I/O node - serves as output during mux mode, input during demux mode |
| 18 | VSS | Negative supply rail - must be connected to system ground or negative reference |
| 19 | A | LSB address input - controls bit-0 of 4-bit binary decode (Y0/Y1, Y2/Y3, etc.) |
| 20 | B | Bit-1 address input - selects pair group (Y0–Y3, Y4–Y7, Y8–Y11, Y12–Y15) |
| 21 | C | Bit-2 address input - determines quadrant (Y0–Y7 vs Y8–Y15) |
| 22 | D | MSB address input - selects upper/lower half (Y0–Y7 or Y8–Y15) |
| 23 | INHIBIT | Active-high enable - logic '1' forces all switches OFF regardless of address state |
| 24 | VDD | Positive supply rail - powers internal logic and switch transistors; decoupling capacitor required |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage operation | Rated for 20V absolute maximum - supports industrial ±10V signal ranges and 15V logic interfaces |
| Matched ON resistance | ΔRON ≤ 5Ω typ at VDD = 15V - ensures <0.05% channel-to-channel gain mismatch in ratiometric measurements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4067BM | Same die, SOIC-24 package - 1.27mm pitch, surface-mount only | Requires PCB rework for SMT assembly; identical electrical specs and timing | Select for space-constrained boards where through-hole is not feasible |

FAQ
What is the maximum analog signal voltage range supported by the CD4067BE?
The CD4067BE supports analog signals from VSS to VDD. With VDD–VSS up to 18V (recommended) and absolute maximum 20V, it handles ±10V differential signals or 0–15V unipolar ranges. This makes CD4067BE suitable for industrial process control interfaces where signals exceed standard 5V logic levels.
Does the CD4067BE require external pull-up resistors on address lines A–D or INHIBIT?
No, the CD4067BE does not require external pull-up resistors. Its CMOS inputs have high impedance and built-in protection networks; VIH is guaranteed ≥70% VDD and VIL ≤30% VDD across the full 3V–18V supply range. Direct connection to microcontroller GPIOs or logic gates is sufficient for reliable operation of CD4067BE.
Can the CD4067BE be used in demultiplexer mode, and how is it configured?
Yes, CD4067BE operates bidirectionally. In demultiplexer mode, apply the analog signal to pin 17 (COMMON OUT/IN), and route outputs to any of pins 1–16 (Y0–Y15) based on A/B/C/D address inputs. The INHIBIT pin disables all outputs simultaneously - enabling CD4067BE to function as a 1-to-16 analog signal distributor in test equipment or calibration systems.
What is the typical settling time of the CD4067BE after channel selection?
Settling time depends on load: with RL = 10kΩ and 10ns input rise/fall, CD4067BE settles within 1200ns at VDD = 5V and 800ns at VDD = 15V. For precision applications, use a 100nF ceramic decoupling capacitor at VDD and minimize trace inductance to achieve specified performance - critical for accurate sampling in CD4067BE-based data loggers.
Is the CD4067BE pin-compatible with other members of the CD40x7B family, such as CD4097B?
No, CD4067BE is not pin-compatible with CD4097B. While both are 24-pin devices, CD4067BE has 16 individual channel I/Os (pins 1–16) and one COMMON terminal (pin 17), whereas CD4097B provides dual 8-channel banks (X and Y) with separate COMMON X (pin 1) and COMMON Y (pin 17). PCB layout and firmware addressing must be redesigned when substituting between these variants of CD4067BE and CD4097B.
