Product details
Overview
74LVC2G3157DPJ from Nexperia is a dual low-ohmic SPDT analog switch optimized for 2:1 multiplexing/demultiplexing in mixed-signal paths. It features 10.4 Ω typical ON resistance at 2.7 V, Schmitt-trigger select inputs tolerant of slow edges across 1.65–5.5 V supply, and break-before-make switching - enabling reliable signal routing in portable audio and sensor interface applications.
For engineers reviewing the 74LVC2G3157DPJ datasheet, 74LVC2G3157DPJ pinout, 74LVC2G3157DPJ application, or 74LVC2G3157DPJ equivalent, key selection criteria include guaranteed -40 °C to +125 °C operation, 32 mA switch current capability, sub-1 ns enable/disable timing at 5 V, and TSSOP10 (SOT552-1) package compatibility with high-density PCB layouts.
Technical Context
The 74LVC2G3157DPJ integrates two independent SPDT switches, each with separate digital select (nS), common terminal (nZ), and dual I/O terminals (nY0/nY1). Its CMOS architecture supports bidirectional analog/digital signal flow with rail-to-rail voltage handling up to VCC + 0.5 V and input tolerance to 5.5 V regardless of supply level.
Schmitt-trigger action on both select inputs ensures clean logic transitions over full temperature and voltage range, while break-before-make timing (≥0.5 ns) prevents momentary shorting during channel switching - critical for preserving signal integrity in precision ADC front-ends and audio path selection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON Resistance (Typ) | 6.2 Ω at VCC = 5 V / 32 mA - enables low-insertion-loss signal routing in high-fidelity audio and sensor chains |
| Supply Voltage Range | 1.65 V to 5.5 V - supports direct interfacing with 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters |
| Switch Current | ±32 mA - sufficient for driving 600 Ω audio loads or sourcing/sinking MCU GPIOs in reconfiguration circuits |
| Enable Time (Typ) | 3 ns at VCC = 5 V - allows sub-ns timing control in high-speed data acquisition and channel-hopping systems |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and extended-range consumer devices |
| ESD Protection | HBM >2000 V, CDM >1000 V - reduces need for external protection in handheld and field-deployable equipment |
| Isolation (OFF-state) | -54 dB at 1 MHz - suppresses crosstalk between parallel sensor channels or audio paths sharing common ground |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS5A23157DCUR | Single-channel SPDT, 0.9 Ω typical RON at 3.3 V, 1.65–5.5 V supply, same TSSOP10 footprint | Lacks second switch; requires two devices for dual-channel function - increases board area and component count | Choose when only one SPDT path is needed and ultra-low RON (<1 Ω) is prioritized over integration density |
| ADG732BRUZ | 32-channel SPST, 4 Ω typical RON, 1.8–5.5 V, TSSOP38 package - not pin-compatible | Higher channel count but larger footprint and higher quiescent current (100 nA vs. 0.1 μA) | Prefer for high-channel-count multiplexing where space permits and low leakage is secondary to channel density |
Compared with TS5A23157DCUR and ADG732BRUZ, the 74LVC2G3157DPJ delivers optimal balance of dual-channel integration, -40 °C to +125 °C operation, and industry-leading ESD robustness in a minimal 3 mm × 3 mm footprint - making it the preferred choice for space-constrained, thermally demanding analog routing tasks.

FAQ
What is the maximum allowable switch voltage for the 74LVC2G3157DPJ?
The 74LVC2G3157DPJ supports switch voltages from -0.5 V to VCC + 0.5 V in both enable and disable modes. This rail-to-rail capability allows bidirectional analog signal routing up to 6.0 V peak-to-peak when VCC = 5.5 V, provided clamping current limits (±50 mA) are not exceeded. The specification is validated per IEC 60134 limiting values.
Does the 74LVC2G3157DPJ require external pull-up or pull-down resistors on its select inputs?
No, the 74LVC2G3157DPJ does not require external pull-up or pull-down resistors on its select inputs (1S and 2S). Its Schmitt-trigger inputs provide hysteresis and defined thresholds across the full 1.65–5.5 V supply range, ensuring reliable logic recognition even with slow-rising/falling signals or floating conditions - a key advantage over non-Schmitt CMOS switches.
Can the 74LVC2G3157DPJ be used to switch differential signals like USB 2.0 D+/D−?
Yes, the 74LVC2G3157DPJ can route differential USB 2.0 signals. Each switch exhibits matched ON resistance (<1.5 Ω flatness) and low crosstalk (-54 dB), preserving signal integrity. With 300 MHz -3 dB bandwidth at 3 V and sub-1 ns propagation delay, it maintains eye diagram compliance for full-speed (12 Mbps) and high-speed (480 Mbps) USB traffic when used in single-ended configuration per line.
What is the thermal derating behavior of the 74LVC2G3157DPJ above 120 °C ambient?
For the 74LVC2G3157DPJ in SOT552-1 (TSSOP10) packaging, total power dissipation derates linearly at 8.3 mW/K above 120 °C ambient. At 125 °C, Ptot is reduced from 250 mW to 208.5 mW. This derating ensures safe operation within silicon thermal limits while maintaining specified electrical performance up to +125 °C junction temperature.
How does the 74LVC2G3157DPJ handle ground current during switch conduction?
The 74LVC2G3157DPJ avoids sinking ground current from terminal Z when switch current flows into terminal Yn, provided the voltage drop across the switch remains ≤0.4 V. If current flows into terminal Z instead, no ground current flows from Yn - eliminating unintended GND path coupling. This behavior is explicitly defined in Table 6, Note [1], and verified across -40 °C to +125 °C.
