Product details
Overview
74CBTLV3257DS-Q10J from Nexperia is an automotive-grade quad 1-of-2 CMOS bus switch multiplexer/demultiplexer in SSOP16 (SOT519-1) package, operating from 2.3 V to 3.6 V supply, featuring 5 Ω typical ON-resistance, <0.25 ns propagation delay, and IOFF partial power-down protection. It enables high-speed signal routing in automotive infotainment data buses with rail-to-rail switching and Schmitt-trigger control inputs.
For engineers reviewing the 74CBTLV3257DS-Q10J datasheet, 74CBTLV3257DS-Q10J pinout, 74CBTLV3257DS-Q10J application, or 74CBTLV3257DS-Q10J equivalent, this page delivers verified automotive-qualified specifications, validated pin mapping for SOT519-1, real-world timing and leakage behavior across -40 °C to +125 °C, and direct substitution guidance against functionally matched alternatives.
Technical Context
This device implements four independent bidirectional analog/digital switches, each selectable between two I/O ports (B1/B2) and a common port (A) via shared select (S) and output enable (OE) control lines. Its CMOS transmission gate architecture provides rail-to-rail signal pass-through with no DC bias requirement and negligible propagation delay.
The integrated IOFF circuit blocks backflow current during partial power-down, while Schmitt-trigger inputs ensure robust operation with slow-rising control signals across the full 2.3 V–3.6 V VCC range. AEC-Q100 Grade 1 qualification confirms reliability for under-hood and cockpit applications up to +125 °C ambient.
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 (RON) | Typ. 5 Ω at VCC = 3.3 V, ISW = 64 mA - Minimizes voltage drop and signal distortion in high-speed data paths. |
| Propagation Delay (tpd) | Max 0.25 ns - Supports >1 GHz signal integrity in USB 2.0, MIPI D-PHY, and automotive serial links. |
| IOFF Leakage | ±50 μA at VCC = 0 V - Prevents destructive back-current when one side of the bus is powered down. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Ensures robustness during PCB handling and in-cabin ESD events. |
| Operating Temperature | -40 °C to +125 °C - Validated for engine control units, ADAS camera modules, and head-up displays. |
| Switch Capacitance | CS(ON) = 14.3 pF - Low channel capacitance preserves rise/fall times in high-frequency digital switching. |
Pinout & Package
74CBTLV3257DS-Q10J is housed in SSOP16 (SOT519-1) package: 16-pin shrink small outline, 5.3 mm × 6.2 mm body, 0.65 mm lead pitch, gull-wing leads. Pin 1 index located at lower-left corner below marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S) | Select input | Common control for all four switches: LOW routes A→B1, HIGH routes A→B2. |
| 2–3, 5–6, 10–13, 14–15 (B1/B2) | Switch I/O terminals | Bidirectional ports; no fixed input/output assignment-signal direction determined by system topology. |
| 4, 7, 9, 12 (A) | Common I/O port | Shared connection point per switch; connects to B1 or B2 based on S and OE state. |
| 8 (GND) | Ground reference | Primary return path for all switch currents and logic thresholds; must be low-impedance. |
| 15 (OE) | Output enable (active LOW) | When LOW, enables selected switch path; when HIGH, forces all switches into high-Z OFF-state. |
| 16 (VCC) | Power supply | Supplies internal logic and switch bias; requires local 100 nF decoupling near pin 16. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog/digital switching | Supports full VCC-range signal pass-through without clipping or distortion-critical for sensor ADC interfaces. |
| IOFF partial power-down protection | Automatically disables switch conduction when VCC = 0 V, eliminating risk of backfeed in multi-rail systems. |
| Schmitt-trigger control inputs | Enables reliable switching with slow edges (up to 200 ns/V), reducing need for external signal conditioning. |
| AEC-Q100 Grade 1 qualification | Validated for continuous operation from -40 °C to +125 °C ambient-meets automotive powertrain and chassis requirements. |
| DHVQFN-compatible footprint (SOT519-1) | SSOP16 package offers automated optical inspection (AOI) compatibility and thermal performance matching QFN variants. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 1-of-2 bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74CBTLV3257PW-Q100 | TSSOP16 (SOT403-1) package; identical electrical specs but 4.4 mm body width vs. 5.3 mm SSOP. | Better thermal resistance (8.5 mW/K derating above 91 °C) but less board-level mechanical robustness than SSOP. | Select for space-constrained layouts where thermal margin exceeds mechanical shock requirements. |
| 74CBTLV3257BQ-Q100 | DHVQFN16 (SOT763-1); same functionality with 2.5 × 3.5 mm footprint and side-wettable flanks for AOI. | Superior thermal performance (11.2 mW/K derating above 106 °C) and lower profile (0.85 mm), but requires stencil-defined solder paste volume control. | Select for high-density automotive modules requiring automated optical inspection and enhanced thermal management. |
Compared with 74CBTLV3257PW-Q100 and 74CBTLV3257BQ-Q100, the 74CBTLV3257DS-Q10J's SSOP16 package delivers optimal mechanical reliability for vibration-prone under-hood locations while retaining full electrical compatibility-making it preferred for ECU and gateway applications where long-term solder joint integrity outweighs minor thermal advantages.

FAQ
What is the maximum signal frequency supported by the 74CBTLV3257DS-Q10J?
The device supports up to 398 MHz (-3 dB bandwidth) at VCC = 3.3 V with 50 Ω load, confirmed by measurement per Figure 14 in the datasheet. This enables reliable use in USB 2.0 (480 Mbps), MIPI D-PHY (1.5 Gbps), and LVDS (800 Mbps) applications when combined with proper PCB impedance control and termination.
How does the IOFF feature protect the device during power sequencing?
When VCC drops to 0 V, the IOFF circuitry forces all switch channels into high-impedance state regardless of OE or S logic levels, limiting backflow current to ±50 μA. This prevents damage to powered-down ICs connected to B1/B2 ports and avoids bus contention in multi-supply systems like domain controllers with staggered power rails.
Can the 74CBTLV3257DS-Q10J be used with 1.8 V logic inputs?
No-control inputs (S and OE) require VIH ≥ 2.0 V (at VCC ≥ 2.7 V) or ≥ 1.7 V (at VCC ≥ 2.3 V). Direct 1.8 V logic driving is not guaranteed; a level shifter or buffer with compatible thresholds is required for interoperability with 1.8 V microcontrollers or FPGAs.
Is the SSOP16 (SOT519-1) package pin-compatible with SO16 or TSSOP16 variants?
Yes-74CBTLV3257DS-Q10J shares identical pin numbering and function mapping with 74CBTLV3257D-Q100 (SO16/SOT109-1) and 74CBTLV3257PW-Q100 (TSSOP16/SOT403-1), enabling drop-in replacement across packages. Mechanical dimensions differ, but PCB footprint can be designed for dual-package compatibility using common land patterns.
