Product details
Overview
74LVC1G3157GN,132 from NXP Semiconductors is a single-pole double-throw (SPDT) analog multiplexer/demultiplexer in an ultra-thin XSON6 package (0.9 × 1.0 × 0.35 mm), operating from 1.65 V to 5.5 V supply, featuring 6.5 Ω typical ON resistance at 3.3 V and break-before-make switching for signal integrity in audio routing and sensor interface applications.
For engineers reviewing the 74LVC1G3157GN,132 datasheet, 74LVC1G3157GN,132 pinout, 74LVC1G3157GN,132 application, or 74LVC1G3157GN,132 equivalent, key selection criteria include its Schmitt-trigger select input for noise immunity across voltage rails, ±32 mA switch current capability, −40 °C to +125 °C temperature rating, and low charge injection (5.0 pC at 3.3 V) critical for precision data acquisition systems.
Technical Context
The 74LVC1G3157GN,132 implements a CMOS transmission gate architecture with dual independent channel paths (Y0 and Y1) routed to a common terminal (Z), controlled by a single digital select input (S) with integrated Schmitt trigger for robust edge detection under slow-rising input conditions. Its rail-to-rail analog switching supports bidirectional signal flow without polarity constraints.
Break-before-make timing (≥0.5 ns) prevents momentary shorting between Y0 and Y1 during state transitions, while ON-resistance flatness ≤3.5 Ω (at 2.7 V, 12 mA) ensures minimal signal distortion across the full input voltage range - essential for high-fidelity audio and precision instrumentation front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.65 V to 5.5 V - enables direct interfacing with 1.8 V, 2.5 V, 3.3 V, and 5 V logic/systems without level shifters. |
| ON Resistance (Typ) | 6.5 Ω at VCC = 3.3 V - delivers low insertion loss and minimal signal attenuation in analog signal paths. |
| Switch Current | ±32 mA - supports driving moderate loads such as op-amp inputs, ADC references, or small-signal transducers. |
| Operating Temp | −40 °C to +125 °C - qualified for automotive under-hood, industrial control, and extended-temperature embedded systems. |
| Charge Injection | 5.0 pC at VCC = 3.3 V - minimizes voltage glitches at switched nodes, preserving accuracy in sample-and-hold and multiplexed ADC circuits. |
| Isolation (OFF) | −40 dB at 10 MHz - suppresses crosstalk between inactive channels, critical in multi-sensor monitoring systems. |
| Propagation Delay | 0.8 ns max at VCC = 3.3 V - enables fast channel switching in real-time signal routing and test equipment. |
Pinout & Package
XSON6 package (SOT1115): extremely thin small outline, no leads, 6-terminal surface-mount package with body dimensions 0.9 mm × 1.0 mm × 0.35 mm; pin 1 indicator located on lower-left corner below marking code "YJ".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Y1) | Independent I/O channel | Connects to second analog source/sink; bidirectional path when selected via S = HIGH. |
| 2 (GND) | Ground reference | Provides return path for switch current and stabilizes internal bias networks; must be low-impedance. |
| 3 (Y0) | Independent I/O channel | Connects to first analog source/sink; bidirectional path when selected via S = LOW. |
| 4 (Z) | Common I/O terminal | Shared analog node - routes signal to Y0 (S = L) or Y1 (S = H); supports true bidirectional operation. |
| 5 (VCC) | Power supply | Supplies core logic and switch bias; decoupling capacitor (100 nF) required within 2 mm of pin. |
| 6 (S) | Digital select input | Schmitt-triggered control line tolerant of slow edges; accepts 0–5.5 V logic levels regardless of VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guarantees ≥0.5 ns isolation between Y0 and Y1 during transition, preventing signal shorting in mixed-signal routing. |
| Schmitt-trigger select input | Enables reliable operation with slow-rising/falling control signals across full 1.65–5.5 V VCC range, reducing EMI susceptibility. |
| Rail-to-rail analog operation | Supports input/output voltages from GND to VCC without clipping, enabling compatibility with unipolar and bipolar signal chains. |
| Low ON-resistance flatness | ≤3.5 Ω variation over full input swing at 2.7 V - maintains consistent gain and linearity in precision measurement paths. |
| ESD robustness | HBM >2000 V and MM >200 V - reduces need for external protection in handheld and field-deployable equipment. |
Applications
| Audio Signal Routing | Sensor Multiplexing |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS5A23157DCUR | Higher ON resistance (10 Ω typ at 3.3 V), wider −40 °C to +85 °C temp range, same 6-pin X2SON package. | Limited to commercial-temperature applications; less suitable for under-hood automotive or industrial control. | Choose TS5A23157DCUR only if cost sensitivity outweighs temperature and RON requirements. |
| ADG819BRMZ-REEL7 | Lower charge injection (0.6 pC), but narrower 1.8–5.5 V supply range and higher 7.5 Ω RON at 3.3 V; MSOP-8 package (larger footprint). | Preferred for ultra-low-glitch sample-and-hold; unsuitable where board area or wide VCC tolerance is critical. | Select ADG819BRMZ-REEL7 when sub-pC charge injection dominates design priorities over size and supply flexibility. |
Compared with TS5A23157DCUR and ADG819BRMZ-REEL7, the 74LVC1G3157GN,132 uniquely balances ultra-small XSON6 footprint, extended temperature support, and optimized RON/charge injection trade-off for space-constrained industrial and automotive signal routing.

FAQ
What is the maximum allowable switch voltage for the 74LVC1G3157GN,132?
The 74LVC1G3157GN,132 supports switch voltages from −0.5 V to VCC + 0.5 V in both enable and disable modes. This rail-to-rail capability allows analog signals spanning the full supply range (e.g., 0 V to 3.3 V when VCC = 3.3 V) without clamping or distortion, provided switch current remains within ±32 mA limits.
Does the 74LVC1G3157GN,132 require external pull-up or pull-down resistors on the S pin?
No, the 74LVC1G3157GN,132 integrates a Schmitt-trigger input on the S pin with built-in hysteresis, eliminating the need for external biasing resistors. The input accepts 0–5.5 V logic levels independently of VCC, ensuring robust operation even with noisy or slow-rising control signals in electrically harsh environments.
Can the 74LVC1G3157GN,132 be used in bidirectional signal paths?
Yes, the 74LVC1G3157GN,132 supports fully bidirectional analog signal flow between Z and either Y0 or Y1. Its CMOS transmission gate structure imposes no directionality - signals pass equally well from Z to Yn or Yn to Z, making it ideal for shared bus architectures and reversible sensor interfaces.
What is the thermal derating behavior of the 74LVC1G3157GN,132 above 118 °C?
For the XSON6 package (SOT1115), the 74LVC1G3157GN,132 total power dissipation derates linearly at 7.8 mW/K above 118 °C. At 125 °C ambient, Ptot reduces from 250 mW to approximately 195 mW - a critical consideration for high-temperature automotive or industrial deployments where sustained thermal stress is expected.
How does the 74LVC1G3157GN,132 handle ground current during switching events?
The 74LVC1G3157GN,132 avoids sinking GND current from terminal Z when switch current flows into Yn, provided the voltage drop across the bidirectional switch stays ≤0.4 V. If current flows into Z instead, no GND current is generated - a design feature that simplifies grounding schemes and reduces noise coupling in sensitive analog sections.
