Product details
Overview
74CBTLV3257PW-Q10J from Nexperia is an automotive-grade quad 1-of-2 analog multiplexer/demultiplexer in TSSOP16 package, operating from 2.3 V to 3.6 V supply, with 5 Ω typical ON-resistance, <0.25 ns propagation delay, and AEC-Q100 Grade 1 qualification for use in vehicle infotainment signal routing and ADAS sensor interface switching.
For engineers reviewing the 74CBTLV3257PW-Q10J datasheet, 74CBTLV3257PW-Q10J pinout, 74CBTLV3257PW-Q10J application, or 74CBTLV3257PW-Q10J equivalent, key selection criteria include rail-to-rail analog switching capability, IOFF-enabled partial power-down protection, Schmitt-trigger control inputs for noise immunity across full VCC range, and guaranteed operation from −40 °C to +125 °C.
Technical Context
This device implements four independent bidirectional analog switches, each selectable between two I/O ports (B1/B2) via a shared select (S) input and globally enabled/disabled by an active-low output enable (OE) input. All switches exhibit symmetrical ON-resistance (<8 Ω max at 3.6 V, 25 °C) and support rail-to-rail voltage swing on all data paths.
IOFF circuitry ensures zero backflow current when VCC = 0 V, enabling hot insertion and safe partial power-down operation. Schmitt-trigger action on S and OE inputs guarantees clean logic transitions even with slow-rising control signals across the full 2.3 V–3.6 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.3 V to 3.6 V - Enables direct interface with 2.5 V and 3.3 V logic domains without level translation. |
| ON Resistance | Typ. 4.0 Ω at VCC = 3.3 V, ISW = 64 mA - Minimizes signal attenuation and distortion in high-speed analog/data bus applications. |
| Propagation Delay | Max 0.25 ns - Supports >1 GHz signal bandwidth with negligible timing skew in multiplexed data paths. |
| Operating Temperature | −40 °C to +125 °C - Qualified for under-hood and powertrain electronics per AEC-Q100 Grade 1. |
| IOFF Leakage | ±50 μA at VCC = 0 V - Prevents damaging back-current during system power sequencing or hot-swap events. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Robust handling in automated PCB assembly and automotive service environments. |
| Switch Capacitance | CS(ON) = 14.3 pF - Low channel capacitance preserves signal integrity in high-frequency analog switching (e.g., camera sensor MIPI lanes). |
Pinout & Package
TSSOP16 package (SOT403-1), 4.4 mm body width, 0.65 mm lead pitch, thermally enhanced for automotive reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S) | Select input | Common control for all four multiplexers; LOW selects B1, HIGH selects B2 on each channel. |
| 2–3, 5–6, 10–13, 14–15 (1B1–4B2) | Switch port terminals | Bidirectional analog I/O pairs; no intrinsic directionality-signal flow determined by external biasing. |
| 4, 7, 9, 12 (1A–4A) | Common output/input node | Shared connection point per channel; connects to selected B1 or B2 when OE = LOW. |
| 8 (GND) | Ground reference | Primary return path for all switch currents and logic inputs; must be low-impedance for noise control. |
| 15 (OE) | Output enable (active LOW) | Global disable: HIGH forces all switches into high-Z OFF-state regardless of S state; pull-up required at power-up. |
| 16 (VCC) | Supply voltage | Power rail for internal logic and switch biasing; decoupling capacitor mandatory near pin for transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports full 0 V to VCC signal swing on all ports-enables seamless integration with ADCs, DACs, and sensor interfaces. |
| IOFF partial power-down | Blocks current flow when VCC = 0 V-critical for modular systems where subsystems power up/down independently. |
| Schmitt-trigger control inputs | Hysteresis on S and OE pins tolerates slow edges and noisy supply rails-eliminates need for external debouncing in harsh automotive environments. |
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation with extended lifetime testing-meets OEM requirements for engine control and ADAS modules. |
| Side-wettable flanks (SWF) | TSSOP package variant supports automated optical inspection (AOI) of solder joints-reduces field failure risk in high-volume automotive manufacturing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 1-of-2 analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS3A4752PWR | Higher ON-resistance (12 Ω typ), no AEC-Q100 qualification, wider 1.65–3.6 V supply range | Targeted at industrial/commercial PCBs-not validated for automotive thermal cycling or humidity testing | Choose only if AEC-Q100 compliance is unnecessary and lower cost outweighs reliability trade-offs. |
| 74LVC1G3157GW,125 | Single-channel, smaller SC-88 package, 6 Ω ON-resistance, same AEC-Q100 Grade 1 rating | Requires four discrete units to match quad functionality-increases board area and assembly cost | Prefer when space constraints prohibit TSSOP16 or when channel isolation requirements exceed quad-package crosstalk limits. |
Compared with TS3A4752PWR and 74LVC1G3157GW,125, the 74CBTLV3257PW-Q10J delivers superior thermal robustness, lower ON-resistance, and integrated quad architecture-making it optimal for space-constrained, high-reliability automotive signal routing where qualification and performance consistency are non-negotiable.

FAQ
What is the maximum allowable signal voltage swing on the 74CBTLV3257PW-Q10J switch ports?
The device supports rail-to-rail analog switching: signal voltage on any A or B port may range continuously from 0 V to VCC (2.3 V–3.6 V). Exceeding VCC or going below GND violates absolute maximum ratings and risks latch-up or permanent damage, as confirmed in Table 5 (VSW = −0.5 V to VCC + 0.5 V).
Does the 74CBTLV3257PW-Q10J require external pull-up resistors on OE and S pins?
Yes-OE must be pulled up to VCC via an external resistor to guarantee high-impedance OFF-state during power-up; the datasheet specifies current-sinking capability determines minimum resistance value. S does not require pull-up but benefits from one in noisy environments due to Schmitt-trigger hysteresis.
Can the 74CBTLV3257PW-Q10J be used to switch differential signals such as LVDS or RS-485?
No-this is a single-ended analog switch with no matched pair routing, common-mode rejection, or differential drive capability. Its 5 Ω ON-resistance and 14.3 pF ON-capacitance are optimized for single-ended CMOS/TTL/MIPI signals, not differential protocols requiring controlled impedance and skew matching.
How does the IOFF feature behave when VCC is ramping during power-up?
IOFF activates automatically when VCC drops below ~0.8 V, disabling all switches and blocking back-current. During power-up, the device remains in high-Z until VCC exceeds the minimum functional threshold (~2.3 V); OE must be held HIGH (via pull-up) until stable VCC is established to prevent unintended conduction.
