Product details

Overview

PI3A223ZMEX from Diodes Incorporated is a dual SPDT analog switch fabricated in CMOS technology, designed for low-distortion audio/video signal routing and power path switching in portable electronics. It delivers 0.45 Ω on-resistance at 4.2 V, rail-to-rail signal handling (0 V to V_DD), and break-before-make switching with 8 ns delay to prevent signal shorting. Used in headset switching and relay replacement circuits where low R_ON and high off-isolation are critical.

For engineers reviewing the PI3A223ZMEX datasheet, PI3A223ZMEX pinout, PI3A223ZMEX application, or PI3A223ZMEX equivalent, key selection criteria include on-resistance flatness (<0.26 Ω over signal range), crosstalk rejection (–108 dB @ 100 kHz), isolation (–83 dB @ 100 kHz), and compatibility with 1.8–4.2 V logic-supply systems.

Technical Context

The PI3A223ZMEX implements two independent SPDT switches with complementary control inputs (IN1/IN2), each selecting between normally closed (NC) and normally open (NO) paths to a shared common (COM). Its CMOS architecture enables bidirectional analog signal flow and supports both analog multiplexing and digital bus switching roles.

Break-before-make timing (8 ns typical at 4.2 V) ensures no overlap between NC and NO conduction states during transition. The device operates across –40°C to +85°C with 4 kV HBM ESD rating and maintains <1 μA leakage in both on- and off-states under full voltage swing conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
On-Resistance	0.45 Ω at V_DD = 4.2 V - enables minimal voltage drop and power loss in battery-powered signal paths
Signal Range	Rail-to-rail (0 V to V_DD) - supports full-swing audio and logic-level signals without clipping
Off Isolation	–83 dB @ 100 kHz - suppresses unwanted coupling between inactive channels in multi-source systems
Crosstalk Rejection	–108 dB @ 100 kHz - preserves signal integrity when routing adjacent audio or video channels
Supply Voltage	1.8 V to 4.2 V - compatible with Li-ion battery discharge profile and modern low-voltage SoC I/O domains
Turn-On/Off Time	13 ns / 38 ns at 4.2 V - supports fast switching in dynamic routing applications like USB/audio port sharing
ESD Rating	4 kV HBM - provides robustness against handling-induced transients in assembly and end-user environments

Pinout & Package

Package: 10-pin Ultra-thin Quad Flat No-Lead (UQFN), 1.4 mm × 1.8 mm, 0.4 mm pitch, ZM code, Pb-free and RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
1	V_DD	Positive supply input - powers internal CMOS switch array and level-shifting logic
2	NO1	Normally open terminal of Switch 1 - connects to COM1 only when IN1 = HIGH
3	COM1	Common output/data port of Switch 1 - bidirectional signal path shared by NO1 and NC1
4	IN1	Digital control input for Switch 1 - HIGH selects NO1→COM1; LOW selects NC1→COM1
5	NC1	Normally closed terminal of Switch 1 - connects to COM1 only when IN1 = LOW
6	GND	Ground reference - return path for supply current and signal common reference
7	NC2	Normally closed terminal of Switch 2 - connects to COM2 only when IN2 = LOW
8	IN2	Digital control input for Switch 2 - independent of IN1; enables dual-channel routing
9	COM2	Common output/data port of Switch 2 - bidirectional path shared by NO2 and NC2
10	NO2	Normally open terminal of Switch 2 - connects to COM2 only when IN2 = HIGH

Key Features

Feature	Design Value
Break-before-make switching	8 ns guaranteed minimum dead time prevents momentary shorting between NC and NO paths during state change
Low on-resistance flatness	0.22 Ω max variation over full signal range at 4.2 V - ensures consistent gain and THD performance across audio band
High off-isolation	–83 dB @ 100 kHz - isolates unused audio sources to avoid bleed-through in multi-input headset jacks
Rail-to-rail analog operation	Supports 0 V to V_DD signal swing - eliminates need for external biasing in single-supply portable designs
Ultra-small UQFN package	1.4 mm × 1.8 mm footprint - saves PCB area in space-constrained mobile applications like smartphones and wearables

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual SPDT analog switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TSM1022YFNR	Higher on-resistance (0.8 Ω typ. at 3.3 V); smaller 1.2 mm × 1.6 mm WLCSP package; no break-before-make guarantee	Limited to low-current signal routing (≤50 mA); unsuitable for power path selection due to R_ON and timing uncertainty	Choose when board area is primary constraint and signal integrity requirements are relaxed
MAX4680EUA+	Wider supply range (1.8–5.5 V); higher off-isolation (–92 dB @ 100 kHz); SO-8 package (larger, leaded)	Better suited for industrial test equipment requiring higher voltage margin and creepage; incompatible with ultra-compact mobile layouts	Choose when extended voltage headroom or legacy through-hole assembly is required

Compared with TSM1022YFNR and MAX4680EUA+, the PI3A223ZMEX offers optimal balance of ultra-low R_ON, guaranteed break-before-make timing, and miniature UQFN packaging-making it uniquely suitable for space- and performance-critical portable audio routing.

FAQ

What is the maximum continuous current rating per channel?

The PI3A223ZMEX supports ±300 mA continuous current through any NO, NC, or COM terminal. This rating applies across the full operating temperature range (–40°C to +85°C) and ensures reliable conduction without thermal derating in typical portable audio and power routing applications.

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

No. The IN1 and IN2 inputs have defined logic thresholds (VIH ≥ 1.2 V, VIL ≤ 0.5 V) and ≤1 μA leakage, allowing direct connection to GPIOs of modern microcontrollers and baseband processors without external biasing components.

Can PI3A223ZMEX be used for bidirectional analog signal switching?

Yes. The device supports fully bidirectional analog signal flow between NO/NC and COM terminals, with matched on-resistance and capacitance characteristics in both directions-verified by identical R_ON, C_ON, and leakage specs regardless of signal direction.

Is the 10-pin UQFN package compatible with standard reflow soldering profiles?

Yes. The ZM package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports standard lead-free reflow profiles (peak temperature 260°C, 60-second duration above 217°C), enabling compatibility with high-volume SMT assembly lines.
