Product details
Overview
CD74HC4067SM96 from Texas Instruments is a 16-channel analog multiplexer/demultiplexer in SSOP-24 package, supporting bidirectional signal routing across 0–VCC analog voltage range, with 60Ω typical ON resistance at 6V, 19ns max propagation delay, and –55°C to +125°C operating temperature. It enables flexible I/O expansion in data acquisition systems requiring low crosstalk and break-before-make switching.
For engineers reviewing the CD74HC4067SM96 datasheet, CD74HC4067SM96 pinout, CD74HC4067SM96 application, or CD74HC4067SM96 equivalent, key selection criteria include analog channel count, supply voltage compatibility (2–6V), thermal performance in SSOP packaging, and enable-controlled channel isolation for mixed-signal system integration.
Technical Context
This device implements a 1-of-16 binary decoder driving 16 bidirectional analog switches, each with matched ON resistance and low off-leakage (<±0.8µA). Its CMOS silicon-gate architecture delivers LSTTL-speed performance while maintaining HC-series power efficiency.
The enable (E) input globally disables all channels into high-impedance OFF state, and break-before-make timing ensures no transient shorting during channel transitions. Switch bandwidth reaches 89MHz at –3dB, supporting audio and moderate-speed sensor signal routing without distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel count | 16 bidirectional analog channels - supports scalable analog I/O expansion from single common port. |
| Supply voltage | 2V to 6V - compatible with 3.3V and 5V logic domains without level shifting. |
| ON resistance | 60Ω typ at VCC = 6V - minimizes signal attenuation and gain error in precision sensor interfaces. |
| Propagation delay | 13ns max at VCC = 6V - enables sub-50MHz digital control of analog paths with deterministic timing. |
| Switch bandwidth | 89MHz at –3dB - suitable for audio, ultrasonic sensing, and baseband communication signals. |
| Off isolation | –75dB feedthrough - suppresses crosstalk between inactive channels in multi-sensor monitoring. |
| Operating temperature | –55°C to +125°C - qualified for industrial, energy infrastructure, and automotive-adjacent environments. |
Pinout & Package
CD74HC4067SM96 uses a 24-pin SSOP (DB) package measuring 8.20mm × 7.40mm with 0.65mm lead pitch. Pin 1 is marked by a notch or dot in the top-left corner; leads are gull-wing shaped for surface-mount reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | COMMON I/O | Bidirectional analog interface shared across all 16 channels - connects to ADC/DAC or signal conditioning stage. |
| 2–9, 16–23 | I0–I15 | Individual analog switch terminals - each routes independently to COMMON when selected; no internal pull-up/down. |
| 10–11, 13–14 | S0–S3 | 4-bit binary address inputs - determine which of 16 channels connects to COMMON (S0 = LSB). |
| 12 | GND | Analog and digital ground reference - must be low-impedance and separated from noisy digital return paths. |
| 15 | E | Active-low enable - drives all switches OFF when high; required for power gating and fault-safe shutdown. |
| 24 | VCC | Positive supply - powers internal logic and switch driver stages; bypass capacitor (0.1µF) recommended near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | 6ns typical transition gap prevents momentary shorting between channels during address changes. |
| Low ON resistance mismatch | ΔRON ≤ 10Ω - ensures consistent gain and linearity across all 16 channels in ratiometric measurements. |
| Wide analog voltage range | Supports VIS = 0 to VCC - allows rail-to-rail signal handling without external clamping or biasing. |
| High off-state isolation | –75dB feedthrough at 1MHz - maintains signal integrity in multi-channel sensor arrays with shared front-end. |
| Low quiescent current | ICC ≤ 160µA over full temperature range - reduces standby power in battery-operated data loggers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD74HC4067M96 | Same HC logic family and electrical specs, but in SOIC-24 (15.4mm × 10.3mm) - 2.3× larger footprint than SSOP. | Preferred where board space permits and hand-soldering or legacy layout reuse is prioritized. | Select when thermal mass or mechanical robustness outweighs size constraints; identical pinout and function. |
| CD74HCT4067SM96 | HCT variant: TTL-compatible inputs (VIH = 2V min), fixed 4.5–5.5V operation, same SSOP-24 package. | Required only when interfacing directly with legacy 5V LSTTL controllers lacking level-shifting capability. | Choose only if host MCU lacks 3.3V-tolerant GPIO; otherwise CD74HC4067SM96 offers wider supply flexibility and lower power. |
Compared with CD74HC4067M96, CD74HC4067SM96 saves 57% board area while delivering identical analog performance; versus CD74HCT4067SM96, it adds 2–6V supply adaptability and cuts quiescent current by ~30% at 3.3V operation - critical for modern low-voltage embedded designs.

FAQ
What is the maximum analog signal voltage range supported by CD74HC4067SM96?
The CD74HC4067SM96 supports analog input/output voltages from 0V to VCC, enabling rail-to-rail signal handling without external biasing. At VCC = 6V, this provides a full 0–6V range; at VCC = 3.3V, it supports 0–3.3V. This behavior is confirmed in Section 7 (Recommended Operating Conditions) and Section 13 (Analog Channel Specifications) of the TI datasheet SCHS209D.
Does CD74HC4067SM96 support bidirectional signal flow?
Yes, CD74HC4067SM96 is fully bidirectional: any I0–I15 pin can serve as input or output relative to the COMMON pin, with identical ON resistance and capacitance characteristics in both directions. This is explicitly stated in the "Description" section and verified by the symmetric analog channel specifications (e.g., RON, CCOM, CI) in the datasheet.
What is the purpose of the E (Enable) pin on CD74HC4067SM96?
The E pin is an active-low enable that forces all 16 analog switches into the OFF state when driven high, regardless of S0–S3 address inputs. This provides hardware-level channel isolation for safety-critical shutdown, power sequencing, or fault containment - a feature distinct from address decoding alone and documented in Table 4-1 (Truth Table) and Section 4.1.
How does CD74HC4067SM96 achieve break-before-make switching?
CD74HC4067SM96 guarantees a minimum 6ns break interval between channel deactivation and activation during address changes, preventing momentary shorts. This timing is measured under VCC = 4.5V conditions and specified in the "Features" list and Switching Characteristics tables (Sections 11–12), ensuring safe operation in multiplexed power or signal routing.
Is CD74HC4067SM96 compatible with 3.3V microcontrollers?
Yes, CD74HC4067SM96 operates from 2V to 6V and has HC-series logic thresholds (VIH = 1.5V min at VCC = 2V; 3.15V min at VCC = 4.5V), making it fully compatible with 3.3V GPIO outputs. Its input leakage (±0.1µA typ) and low drive requirements ensure reliable interfacing without external level shifters, as confirmed in Sections 8 and 10 of the datasheet.
