Product details

Overview

HCF4066M013TR from STMicroelectronics is a quad bilateral analog switch IC used for bidirectional transmission or multiplexing of analog/digital signals in mixed-signal systems. It operates from 3V to 20V supply, delivers 125Ω typical on-resistance at 15V, maintains ≤5Ω matching between switches, and achieves <0.5% THD at 1kHz with 5Vpp signal-enabling precision sample routing in data acquisition front-ends.

For engineers reviewing the HCF4066M013TR datasheet, HCF4066M013TR pinout, HCF4066M013TR application, or HCF4066M013TR equivalent, key selection criteria include on-resistance flatness over full signal swing, control-input isolation (>10¹²Ω), crosstalk rejection (50dB at 0.9MHz), and guaranteed quiescent current testing up to 20V.

Technical Context

The HCF4066M013TR implements four independent CMOS transmission gates, each with matched p- and n-channel devices biased simultaneously by a single digital control input. Its well-tied architecture eliminates threshold-voltage drift across the signal range, ensuring stable R_ON from V_SS to V_DD.

Each switch supports ±7.5V peak-to-peak analog signals with 40MHz small-signal bandwidth, 65dB on/off voltage ratio at 10kHz, and 10pA typical off-leakage at 10V supply-making it suitable for low-offset, low-distortion signal routing where rail-to-rail conduction and channel matching are critical.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	3V to 20V - supports single-supply (5/10/15V) and dual-supply (±7.5V) operation without level-shifting
Typical On-Resistance (15V)	125Ω - enables low insertion loss and minimal signal attenuation in audio and sensor interfaces
On-Resistance Matching	≤5Ω max mismatch between any two switches - ensures consistent gain/attenuation across multiplexed channels
Total Harmonic Distortion	<0.5% at 1kHz, 5Vpp - preserves waveform fidelity in precision analog switching applications
Off-Leakage Current	10pA typ. at V_DD–V_SS=10V - minimizes offset error and charge injection in sample-and-hold or integrator circuits
Control Input Impedance	10¹²Ω typ. - isolates logic control path from sensitive analog signal paths, preventing loading or coupling
Crosstalk Rejection	50dB typ. at 0.9MHz - suppresses inter-channel interference in multi-channel multiplexers

Pinout & Package

Package: SO-14 (Small Outline, 14-pin, surface-mount). Dimensions per STMicroelectronics mechanical drawing PO13G: 8.55–8.75mm length, 5.8–6.2mm width, 1.27mm pitch.

Pin/Terminal	Circuit Role	Design Meaning
1, 4, 8, 11 (A–D)	Signal I/O Terminal	Bidirectional analog/digital port - connects to signal source or load; no polarity constraint
2, 3, 9, 10 (A–D)	Signal O/I Terminal	Paired with pins 1/4/8/11 to form four independent transmission paths
5, 6, 12, 13	Control Input	Active-high enable per switch - drives corresponding gate pair ON/OFF synchronously
7	V_SS	Negative supply or ground reference - defines lower rail for analog signal swing and bias network
14	V_DD	Positive supply - sets upper rail; supports up to 20V absolute max rating

Key Features

Feature	Design Value
Rail-to-rail analog conduction	Supports VIS = V_SS to V_DD - eliminates clipping in single-supply sensor interfaces
Matched p/n device biasing	Well-tied n-channel configuration - stabilizes threshold voltage across full signal range
Guaranteed quiescent current test	100% tested at 5/10/15/20V - ensures low-power standby behavior in battery-operated systems
Low feedthrough capacitance	0.5pF typical CIOS - reduces transient coupling during fast control transitions
JEDEC JESD13B compliance	Fully conforms to B-series CMOS standard - assures interoperability and reliability across legacy designs

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad bilateral switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CD4066BE	Higher R_ON (300Ω typ. at 15V), no guaranteed quiescent current test, JEDEC JESD7A compliant	Lower cost for non-critical analog routing; less suitable for precision THD-sensitive paths	Select when budget constraints outweigh need for low distortion and leakage performance
74HC4066PW	CMOS logic-level compatible (2–6V V_CC), 50Ω R_ON at 4.5V, but limited to 6V max supply	Optimized for 3.3V/5V digital systems; unsuitable for ±7.5V or 15V analog rails	Select only for low-voltage, high-speed digital multiplexing-not for wide-swing analog signals

Compared with CD4066BE and 74HC4066PW, the HCF4066M013TR uniquely supports 3–20V operation with verified low leakage and THD, making it the only option among the three qualified for precision ±7.5V analog routing and rail-to-rail sensor interface applications.

FAQ

What is the maximum allowable supply voltage for HCF4066M013TR?

The absolute maximum supply voltage (V_DD – V_SS) is 22V, but the recommended operating range is 3V to 20V. Operation above 20V voids parametric guarantees and risks permanent damage. At 20V, quiescent current is tested to 150µA max, and R_ON rises to 300Ω typical.

Can HCF4066M013TR switch negative analog signals?

Yes-it supports true bipolar operation with V_SS at -7.5V and V_DD at +7.5V, enabling ±7.5V peak-to-peak signal handling. The internal well-tied structure maintains low and flat R_ON across the full range, unlike basic CMOS switches that degrade near supply rails.

Is HCF4066M013TR pin-compatible with CD4066?

Yes-HCF4066M013TR is pin-for-pin compatible with CD4066BE and HCF4016B in SO-14 and DIP-14 packages. However, its lower R_ON, tighter matching, and guaranteed quiescent current make it a functional upgrade-not just a drop-in replacement-in performance-critical designs.

What layout considerations minimize crosstalk in PCB design?

Route signal traces for switched channels orthogonally, separate control lines from analog paths with ground guard traces, use local 100nF V_DD/V_SS decoupling near each supply pin, and avoid shared return paths between high-speed control and sensitive analog outputs to maintain the specified 50dB crosstalk rejection.
