Product details
Overview
74HCT4067PW,112 from NXP Semiconductors is a 16-channel analog multiplexer/demultiplexer (SP16T) with TTL-compatible digital inputs, 5 V nominal supply operation, 9 Ω typical ON-resistance at VCC = 4.5 V, and −40 °C to +125 °C operating range. It routes analog or digital signals between one common terminal (Z) and sixteen bidirectional channels (Y0–Y15) under 4-bit binary address control (S0–S3), enabling compact signal routing in data acquisition and sensor interface systems.
For engineers reviewing the 74HCT4067PW,112 datasheet, 74HCT4067PW,112 pinout, 74HCT4067PW,112 application, or 74HCT4067PW,112 equivalent, this device is selected for low-distortion analog switching, precise channel isolation, and direct compatibility with 5 V microcontroller GPIOs-critical for mixed-signal PCB design where signal integrity and logic-level matching are non-negotiable.
Technical Context
The 74HCT4067PW,112 implements a single-pole, 16-throw analog switch architecture with active-low enable (E) and four address lines (S0–S3) decoding one of sixteen Yn terminals to the common Z node. Its internal CMOS transmission gates operate bidirectionally with break-before-make timing to prevent channel shorting during switching transitions.
Input logic thresholds are TTL-compatible (VIL ≤ 0.8 V, VIH ≥ 2.0 V at VCC = 4.5–5.5 V), ensuring robust interfacing with legacy 5 V logic families. The device features integrated input clamp diodes, allowing safe interfacing to voltages exceeding VCC when current-limiting resistors are used.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 4.5 V to 5.5 V - ensures stable operation across industrial 5 V rails with ±10 % tolerance. |
| ON resistance (RON) | 90 Ω typical at VCC = 4.5 V - minimizes signal attenuation and voltage drop in precision analog paths. |
| Channel count | 16 independent Yn terminals + 1 common Z - supports scalable sensor or actuator multiplexing without external logic. |
| Propagation delay | 9 ns typical (Yn to Z) at VCC = 4.5 V - enables high-speed digital multiplexing up to ~50 MHz clock-equivalent rates. |
| OFF-state leakage | ±0.1 μA per channel at VCC = 5.5 V - preserves signal integrity in high-impedance analog front-ends. |
| Operating temperature | −40 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and harsh-environment embedded use. |
| ESD protection | HBM > 2000 V - reduces risk of handling damage during assembly and field service. |
Pinout & Package
TSSOP24 package: plastic thin shrink small outline, 24 leads, body width 4.4 mm, lead pitch 0.65 mm, exposed pad not electrically connected (floating or tied to VCC).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Z | Common I/O | Bidirectional signal path shared across all 16 channels; must be driven within GND–VCC range. |
| Y0–Y15 | Independent I/O | 16 bidirectional analog/digital channels; each connects to Z when selected; no internal pull-up/down. |
| S0–S3 | Address input | 4-bit binary select lines (pins 10, 11, 13, 14); LSB S0, MSB S3; TTL-compatible thresholds. |
| E | Enable input | Active-low control (pin 15); HIGH disables all switches, isolating all Yn and Z terminals. |
| VCC | Supply voltage | Positive supply (pin 24); decoupling capacitor required near pin for noise suppression. |
| GND | Ground reference | 0 V reference (pin 12); must be low-impedance connection to minimize switching noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | Accepts standard 5 V logic levels (VIH ≥ 2.0 V, VIL ≤ 0.8 V), eliminating level-shifter requirements with MCU GPIOs. |
| Low RON mismatch | ≤9 Ω max difference between any two channels at VCC = 4.5 V - ensures consistent gain/attenuation across multiplexed sensor channels. |
| Break-before-make switching | Guaranteed non-overlapping conduction between adjacent channels - prevents momentary shorts during address changes. |
| Clamp diode protection | Integrated input diodes on S0–S3 and E pins - allows safe overvoltage (up to VCC + 0.5 V) with external current limiting. |
| High OFF isolation | −50 dB typical at 1 MHz (VCC = 4.5 V) - suppresses crosstalk between unselected channels in sensitive analog routing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD74HC4067M96 | CMOS-input version (VIH ≥ 3.15 V at VCC = 4.5 V); higher RON (110 Ω typ); same pinout and package. | Requires 3.3 V or 5 V logic with CMOS thresholds; less suitable for direct TTL-level MCU interfacing. | Select when system uses 3.3 V controllers with level-tolerant inputs or when wider VCC range (2–10 V) is needed. |
| MAX4617ESE+ | Single-supply 16-channel mux with lower RON (45 Ω typ), but requires external charge pump for rail-to-rail analog swing; SOIC-24 only. | Superior analog performance but adds complexity and cost; not drop-in compatible due to different enable polarity and biasing. | Choose for ultra-low distortion audio or precision instrumentation where RON < 50 Ω is mandatory and board space permits auxiliary circuitry. |

FAQ
What is the maximum analog signal voltage range supported by the 74HCT4067PW,112?
The 74HCT4067PW,112 supports analog signals from GND to VCC, with VCC rated from 4.5 V to 5.5 V. Signals outside this range may forward-bias internal clamp diodes; if overvoltage is expected, current-limiting resistors must be used per the datasheet guidance to keep input clamping current below ±20 mA. The 74HCT4067PW,112 does not support rail-to-rail operation beyond VCC or below GND without external protection.
Does the 74HCT4067PW,112 support break-before-make switching, and how is it implemented?
Yes, the 74HCT4067PW,112 incorporates inherent break-before-make timing in its internal switch control logic. This ensures that the previously selected channel disconnects fully before the newly addressed channel connects, preventing momentary short circuits between Yn terminals during address transitions. This behavior is guaranteed across the full −40 °C to +125 °C operating range and requires no external timing control. The 74HCT4067PW,112 achieves this via internal propagation delay asymmetry in the decoder path.
Can the 74HCT4067PW,112 be used with 3.3 V microcontrollers?
The 74HCT4067PW,112 is TTL-compatible and specifies VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 4.5–5.5 V, making it compatible with 3.3 V logic outputs only if those outputs meet these thresholds - many 3.3 V MCUs do not guarantee VOH ≥ 2.0 V under load. For reliable interfacing, a level shifter or buffer is recommended. The 74HCT4067PW,112 itself must be powered at 4.5–5.5 V to meet its specified timing and RON performance.
What is the thermal performance of the 74HCT4067PW,112 in TSSOP24 package?
The 74HCT4067PW,112 in TSSOP24 (SOT355-1) has a power dissipation limit of 500 mW at Tamb ≤ 60 °C, derating linearly by 5.5 mW/K above that temperature. At maximum ambient (125 °C), usable power drops to ~143 mW. Thermal resistance θJA is approximately 182 K/W. For continuous 25 mA per channel operation, board layout must include adequate copper pour and thermal vias beneath the exposed pad (if connected) to maintain junction temperature within limits. The 74HCT4067PW,112 datasheet confirms this derating applies specifically to the TSSOP24 variant.
How does the 74HCT4067PW,112 handle OFF-state leakage in high-impedance sensor applications?
The 74HCT4067PW,112 specifies OFF-state leakage of ±0.1 μA per channel at VCC = 5.5 V and 25 °C, rising to ±1.0 μA over −40 °C to +125 °C. In high-impedance sensor applications (e.g., pH electrodes or piezoresistive bridges), this leakage introduces <1 mV error across 10 kΩ source impedance. For sub-mV accuracy, guard traces and low-leakage PCB materials are recommended. The 74HCT4067PW,112's leakage remains stable over temperature and voltage, enabling predictable error budgeting in precision designs.
