Product details
Overview
PSMUX154ZMEX from Diodes Incorporated is a high-bandwidth dual SPDT CMOS analog/bus switch with 4.3Ω on-resistance at 3.0V, 850MHz -3dB bandwidth, and rail-to-rail signal range. It supports 1.8V/2.5V/3.3V logic control, features break-before-make switching, and operates across -40°C to +85°C for portable instrumentation and server I/O routing.
For engineers reviewing the PSMUX154ZMEX datasheet, PSMUX154ZMEX pinout, PSMUX154ZMEX application, or PSMUX154ZMEX equivalent, key selection criteria include on-resistance matching (≤1.0Ω), crosstalk rejection (-90dB @ 1MHz), off-isolation (-80dB @ 1MHz), powered-off protection, and UQFN-10 (1.4mm × 1.8mm) footprint compatibility.
Technical Context
The PSMUX154ZMEX implements two independent SPDT switches with separate A/B common ports and A0/A1/B0/B1 signal paths, controlled by EN and SEL inputs. Its CMOS architecture enables rail-to-rail analog operation from 1.8V to 4.3V VDD while maintaining low channel capacitance (6.0pF ON-state) and near-zero propagation delay (250ps).
Break-before-make timing (7ns minimum) prevents simultaneous conduction during state transitions, ensuring signal integrity in multiplexed data paths. Powered-off protection allows safe I/O voltage presence up to 4.3V even when VDD = 0V, and ESD robustness meets 8kV HBM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 4.3Ω @ VDD = 3.0V - ensures minimal voltage drop and power loss in analog signal paths |
| -3dB Bandwidth | 850MHz - supports high-speed USB 2.0, PCIe Gen1, and video switching without attenuation |
| Crosstalk Rejection | -90dB @ 1MHz - maintains signal fidelity in adjacent channels of multi-channel systems |
| Off Isolation | -80dB @ 1MHz - blocks leakage between inactive and active signal paths |
| Propagation Delay | 250ps - enables precise timing alignment in synchronous bus architectures |
| Channel Capacitance (ON) | 6.0pF - minimizes loading on high-impedance source circuits |
| ESD Protection | 8kV HBM - provides robust handling during board assembly and system integration |
Pinout & Package
PSMUX154ZMEX uses a 10-pin Ultra-thin Quad Flat No-Lead (UQFN) package, code ZM, measuring 1.4mm × 1.8mm with 0.4mm pitch and exposed thermal pad. The package is lead-free, halogen-free, and RoHS 3 compliant.

Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal range | Supports full 0V to VDD swing without clipping - critical for audio and sensor interfaces |
| Break-before-make switching | 7ns guaranteed dead time prevents short-through during transition - avoids bus contention |
| Powered-off protection | Allows up to 4.3V on I/O pins with VDD = 0V - enables hot-swap and level-shifting use cases |
| Low on-resistance flatness | ±0.25Ω variation over signal range - preserves linearity in precision measurement paths |
| Ultra-low charge injection | Typical <1pC - reduces glitch-induced error in sampled-data systems like ADC front-ends |

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 |
|---|---|---|---|
| TMUX1574RTER | Higher on-resistance (6.5Ω @ 3.3V), lower bandwidth (500MHz), no powered-off protection | Limited to low-frequency multiplexing; unsuitable for hot-swap or mixed-voltage I/O | Prefer when cost sensitivity outweighs bandwidth and isolation requirements |
| ADG732BRUZ | 32-channel single-pole single-throw (SPST), higher supply voltage (5.5V), larger TSSOP-48 package | Designed for high-channel-count data acquisition, not dual-path routing | Select only when scaling beyond two SPDT paths or requiring >4.3V operation |
Compared with TMUX1574RTER and ADG732BRUZ, PSMUX154ZMEX delivers superior high-frequency performance, tighter RON matching, and unique powered-off protection-making it optimal for compact, mixed-signal routing in space-constrained portable and server platforms.

FAQ
What is the maximum signal voltage that can be applied to PSMUX154ZMEX I/O pins when VDD = 0V?
The PSMUX154ZMEX supports powered-off protection: I/O pins tolerate voltages from -0.5V to +4.6V even with VDD unpowered. This enables hot-plug capability and safe level translation between powered and unpowered subsystems without external clamping diodes.
Does PSMUX154ZMEX support break-before-make timing across its entire operating temperature range?
Yes - break-before-make delay is guaranteed ≥7ns over -40°C to +85°C ambient temperature. This timing margin prevents momentary short-circuits during switching, ensuring reliable operation in thermally varying environments such as industrial enclosures and mobile devices.
Can PSMUX154ZMEX be used to switch differential signals like USB D+/D− simultaneously?
Yes - both SPDT sections operate independently with matched RON (≤1.0Ω mismatch) and identical dynamic characteristics. When A0/A1 and B0/B1 are routed as complementary pairs, the device maintains phase coherence and common-mode rejection for differential protocols up to 480Mbps.
Is the 10-pin UQFN (ZM) package of PSMUX154ZMEX compatible with standard reflow profiles?
Yes - the ZM package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 and supports standard Pb-free reflow profiles (peak 260°C). Its 0.4mm pitch and exposed thermal pad require controlled stencil design and nitrogen-assisted reflow for optimal solder joint reliability.
