Product details
Overview
PS4157NCEX from Diodes Incorporated is a bidirectional, single-pole double-throw (SPDT) analog switch optimized for negative-voltage signal routing in 5G NR active antenna units. It operates with VEE = −12 V to −4 V, supports switch signal range from VEE to GND, accepts 0–3.3 V positive logic control, delivers RON ≤ 5 Ω at VEE = −10 V, and functions across −55°C to +125°C.
For engineers reviewing the PS4157NCEX datasheet, PS4157NCEX pinout, PS4157NCEX application, or PS4157NCEX equivalent, this device is selected for high-isolation, low-charge-injection switching of analog/digital signals in negative-rail systems where rail-to-rail conduction and fast enable/disable timing are critical.
Technical Context
The PS4157NCEX implements a CMOS-based SPDT architecture with dual N-channel pass transistors controlled by a single positive-voltage select input (S), enabling connection between common port A and either normally-closed B0 or normally-open B1. Its internal design ensures symmetrical conduction and matched RON across both paths under negative supply bias.
It features guaranteed break-before-make timing (tB = 5–135 ns), low charge injection (40–170 pC), high off-isolation (−33 dB at 10 MHz), and wideband performance (200 MHz −3 dB bandwidth), making it suitable for RF front-end signal path selection and precision instrumentation multiplexing in sub-0V domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VEE) | −12 V to −4 V: Enables direct integration into negative-rail power domains without level-shifting circuitry. |
| Switch Signal Range | VEE to GND: Supports full-rail analog/digital signal transmission including −12 V to 0 V swing. |
| ON Resistance (RON) | ≤5 Ω at VEE = −10 V: Minimizes insertion loss and voltage drop in signal paths carrying up to 10 mA. |
| Propagation Delay | ≤2 ns (A to Bn): Ensures minimal timing skew in high-speed data routing applications. |
| Off-Isolation | −33 dB at 10 MHz: Provides strong channel-to-channel crosstalk suppression in RF/mixed-signal environments. |
| Charge Injection | 40–170 pC: Limits transient glitches during switching, critical for precision ADC/DAC interface multiplexing. |
| Operating Temperature | −55°C to +125°C: Qualified for extended industrial and outdoor 5G infrastructure deployments. |
Pinout & Package
PS4157NCEX is housed in a 6-pin SC70 (SOT363) package - compact, surface-mount, lead-free, and RoHS-compliant - with thermal resistance θJA = 400 °C/W and footprint compatible with automated PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B1) | Data Port (Normally Open) | Connects to common port A only when select input S = HIGH; used for alternate signal path selection. |
| 2 (VEE) | Negative Supply Rail | Bias source for internal pass transistors; defines lower bound of switchable signal range. |
| 3 (B0) | Data Port (Normally Closed) | Connected to A when S = LOW; default signal path with no control activation required. |
| 4 (A) | Common Port (COM) | Central bidirectional I/O node; routes signals to B0 or B1 based on S logic state. |
| 5 (GND) | Reference Ground | Signal reference and substrate tie point; must be connected to system ground plane. |
| 6 (S) | Select Input | Positive logic control (0–3.3 V); determines B0/A or B1/A connection with break-before-make timing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail negative signal handling | Supports VIS = VEE to GND, eliminating need for external level shifters in −12 V systems. |
| Low and matched ON resistance | RON ≤ 5 Ω with ∆RON ≤ 0.3 Ω across channels, ensuring balanced gain/attenuation in differential paths. |
| High-speed switching with controlled timing | tPZL/tPLZ ≤ 225 ns and tB = 5–135 ns, enabling reliable sequencing in time-critical RF front ends. |
| Ultra-low charge injection | As low as 40 pC at VEE = −4 V, reducing settling error in precision sampling circuits. |
| Robust ESD protection | 3 kV HBM rating ensures reliability during board handling and system integration. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4677ETA+ | Single-supply operation (±5 V), higher RON (12 Ω), no negative-VIS support | Requires level-shifting for negative-rail signals; unsuitable for direct −12 V to GND routing | Select only if system uses dual ±5 V rails and negative signal swing is limited to −5 V. |
| ADG1419BCPZ-REEL7 | Higher VEE tolerance (−15 V), lower RON (2.2 Ω), but requires −15 V supply and has larger LFCSP package | Offers better performance but demands stricter supply regulation and occupies more PCB area | Prefer for ultra-low-RON designs where −15 V supply is available and space permits larger footprint. |
Compared with MAX4677ETA+ and ADG1419BCPZ-REEL7, PS4157NCEX uniquely balances −12 V operation, SC70 compactness, and sub-5 Ω RON without requiring dual supplies or oversized packaging-making it optimal for space-constrained, negative-rail 5G and test equipment designs.

FAQ
Can PS4157NCEX operate with VEE = −15 V?
No. The absolute maximum VEE rating is −13 V. Operation at −15 V exceeds the maximum rating and risks permanent damage. The recommended operating range is strictly −12 V to −4 V per the datasheet's Recommended Operating Conditions table.
Does PS4157NCEX require external pull-up or pull-down resistors on the S pin?
No. The S pin has defined VIH and VIL thresholds across all VEE conditions (e.g., VIH ≥ 1.8 V at VEE = −12 V), and the datasheet explicitly states the input must not float. A clean 0 V or 3.3 V logic drive suffices-no external biasing is needed or recommended.
What is the maximum capacitive load the PS4157NCEX can drive reliably?
The AC characterization specifies CL = 100 pF for timing parameters (tPZL, tPLZ, etc.). While not an absolute limit, driving loads significantly above 100 pF degrades switching speed and increases transition time; for >100 pF loads, verify timing margins using the provided tPZL/tPLZ vs. VEE curves and consider buffer amplification.
Is PS4157NCEX qualified for automotive AEC-Q100 applications?
No. The datasheet notes that AEC-Q100 qualification requires specific change control and PPAP capability, and PS4157NCEX is not listed as AEC-Q100 qualified. It is rated for extended industrial temperature (−55°C to +125°C) but lacks automotive-grade stress testing, failure rate reporting, or IATF 16949 manufacturing certification.
