Product details
Overview
CLVC257AQPWRG4Q1 from Texas Instruments is an automotive-grade quadruple 2-line to 1-line data selector/multiplexer with 3-state outputs, operating from 2V to 3.6V supply, supporting 5.5V-tolerant inputs and delivering 4.6ns max propagation delay at 3.3V. It enables signal routing in automotive infotainment bus architectures with A/B select control and active-low output enable.
For engineers reviewing the CLVC257AQPWRG4Q1 datasheet, CLVC257AQPWRG4Q1 pinout, CLVC257AQPWRG4Q1 application, or CLVC257AQPWRG4Q1 equivalent, this page delivers verified functional modes, automotive-qualified thermal and ESD specs, TSSOP-16 package details, and validated alternative options for bus multiplexing in ADAS domain controllers and body electronics.
Technical Context
The CLVC257AQPWRG4Q1 implements four independent 2:1 multiplexers sharing a common select (A/B) and output-enable (OE) control. Each channel routes either input A or B to its Y output based on the logic level of A/B, while OE asserts high-impedance state on all outputs when high.
It supports mixed-voltage interfacing: inputs tolerate up to 5.5V regardless of VCC (2–3.6V), enabling direct connection to legacy 5V logic without level shifters. Its 3-state outputs drive shared data buses, and ground bounce (VOLP < 0.8V) and undershoot (VOHV > 2V) are characterized at 3.3V/25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2V to 3.6V - Enables operation across automotive 2.7V cold-crank to 3.6V nominal rail conditions. |
| Input Voltage Tolerance | Up to 5.5V - Allows direct interface with 5V microcontrollers or sensors without external level translation. |
| Max Propagation Delay | 4.6ns at VCC = 3.3V - Supports high-speed bus switching in real-time vehicle networks (e.g., LIN gateway arbitration). |
| Output Drive Strength | ±24mA at VCC = 3V - Sufficient to drive 50Ω transmission lines or fan-out to ≥10 LVC loads. |
| Operating Temperature | –40°C to +125°C - Qualified per AEC-Q100 Grade 1 for under-hood and cabin ECUs. |
| ESD Rating | ±2000V HBM - Meets MIL-STD-883 requirement for robustness in automotive manufacturing and field environments. |
| Power Dissipation Cap | 15.5pF typical Cpd at 3.3V - Enables low dynamic power in always-on modules like door module wake-up logic. |
Pinout & Package
TSSOP-16 (PW) package: 5.00 mm × 6.4 mm body, 1.2 mm max height, lead pitch 0.65 mm, RoHS-compliant NiPdAu finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A/B | Select control input | Common 2:1 selector for all four channels; low = route A inputs, high = route B inputs. |
| OE | Active-low output enable | Drives all Y outputs to high-impedance when high; ensures bus isolation during sleep or fault states. |
| 1A–4A, 1B–4B | Multiplexer data inputs | Eight bidirectional I/O pins accepting 5.5V-tolerant signals; no internal pull-ups or pull-downs. |
| 1Y–4Y | Multiplexer outputs | Four 3-state outputs with controlled VOLP/VOHV; compatible with LVC/LVT logic families. |
| VCC | Power supply | Single 2–3.6V supply; requires local 0.1μF bypass capacitor per TI layout guidelines. |
| GND | Ground reference | Common return for logic and switching currents; must be low-impedance plane for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified | Grade 1 (–40°C to +125°C) certification confirmed for automotive production use in safety-critical domains. |
| 5.5V-tolerant inputs | Enables seamless integration with legacy 5V sensor interfaces or MCU peripherals without external translators. |
| Low ground bounce | VOLP < 0.8V at 3.3V ensures stable logic thresholds during simultaneous output switching in multi-channel systems. |
| Controlled undershoot | VOHV > 2V prevents false triggering of downstream receivers during fast output transitions. |
| Bus-friendly 3-state | OE-controlled high-Z outputs eliminate bus contention in shared-data applications like CAN/LIN transceiver selection. |
Applications
| Automotive Body Control Module (BCM) | ADAS Camera Interface Multiplexing |
|---|---|
Use Scenario: Routing sensor status signals (door open/close, seatbelt latch) from multiple zones to a central microcontroller via shared I²C or GPIO bus. IC Role / Device Role / Timing Role: Quad 2:1 multiplexer selecting between primary and redundant sensor inputs per zone, with OE synchronized to MCU polling cycle. Use Value: Reduces PCB trace count by 50% versus discrete routing; maintains signal integrity across 125°C ambient with <4.6ns timing margin. |
Use Scenario: Switching between front and rear camera video data streams into a single image signal processor (ISP) input lane. IC Role / Device Role / Timing Role: Data selector enabling time-division multiplexing of parallel LVDS or MIPI CSI-2 pixel data paths under A/B control. Use Value: Eliminates need for dual ISP inputs; 5.5V-tolerant A/B and OE pins accept direct 5V camera sync signals without level shifters. |
| Infotainment System Audio Bus Switching | Electric Power Steering (EPS) Diagnostic Port Sharing |
Use Scenario: Dynamically assigning audio source (Bluetooth, USB, tuner) to amplifier input channels in head unit designs. IC Role / Device Role / Timing Role: Four independent 2:1 selectors routing analog or digital audio paths, with OE coordinated to mute during source transition. Use Value: Achieves glitch-free audio switching using 3-state outputs; 2V–3.6V operation matches low-power infotainment SoC rails. |
Use Scenario: Sharing a single diagnostic UART port between EPS motor controller and steering angle sensor firmware update interfaces. IC Role / Device Role / Timing Role: Bidirectional 2:1 data selector isolating debug traffic to one device at a time, controlled by host MCU's A/B and OE signals. Use Value: Reduces connector pin count and harness complexity; ±2000V HBM ESD rating withstands shop-floor handling during service operations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2:1 multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC257APWRQ1 | No Q1 suffix; commercial temperature range (–40°C to +85°C), same electrical specs and pinout. | Not AEC-Q100 qualified; unsuitable for under-hood or safety-critical automotive modules. | Select only for non-automotive industrial or consumer prototypes where qualification is not required. |
| SN74LVC257ADRQ1 | SOIC-16 package (9.9 mm × 6 mm); identical logic function and automotive qualification. | Larger footprint and lower thermal performance (RθJA = 73°C/W vs. 108°C/W for TSSOP). | Choose when board space allows and manual soldering or legacy SOIC compatibility is prioritized over density. |

FAQ
What is the maximum operating temperature for CLVC257AQPWRG4Q1?
The CLVC257AQPWRG4Q1 is rated for continuous operation from –40°C to +125°C, meeting AEC-Q100 Grade 1 requirements. This specification is validated across all electrical parameters in the datasheet, including propagation delay, output drive, and input threshold levels, ensuring reliable performance in engine compartment and EPS control unit environments where ambient temperatures exceed 105°C.
Does CLVC257AQPWRG4Q1 support 5V logic inputs?
Yes, CLVC257AQPWRG4Q1 accepts input voltages up to 5.5V regardless of VCC level (2V–3.6V), as confirmed in Section 4.3 Recommended Operating Conditions. This 5V-tolerance applies to all inputs-including A/B select, OE, and data pins-enabling direct connection to 5V microcontrollers or sensors without external level-shifting circuitry.
What package type is used for CLVC257AQPWRG4Q1?
CLVC257AQPWRG4Q1 uses the TSSOP-16 (PW) package: 5.00 mm × 6.4 mm body size, 0.65 mm lead pitch, 1.2 mm maximum height, with NiPdAu lead finish and MSL Level-1 rating. This package is documented in TI's PACKAGE OPTION ADDENDUM and confirmed in the orderable part number suffix "PW".
How does the output-enable (OE) pin function on CLVC257AQPWRG4Q1?
The OE pin on CLVC257AQPWRG4Q1 is active-low: when high, all four Y outputs enter high-impedance state; when low, outputs drive selected A or B inputs per the A/B control. This behavior is defined in the Function Table (Section 6.3) and enables safe bus sharing in multi-master systems such as diagnostic UART or sensor data aggregation networks.
Is CLVC257AQPWRG4Q1 pin-compatible with SN74LVC257APWRQ1?
Yes, CLVC257AQPWRG4Q1 and SN74LVC257APWRQ1 share identical TSSOP-16 pinout, electrical characteristics, and logic functionality. The only differences are automotive qualification (Q1 suffix), temperature range (125°C vs. 85°C), and part marking-making them drop-in replacements in hardware design, though only CLVC257AQPWRG4Q1 satisfies AEC-Q100 requirements for production vehicles.
