Product details
Overview
CLVC139AQPWRG4Q1 from Texas Instruments is an automotive-qualified dual 2-line-to-4-line decoder/demultiplexer operating from 1.65 V to 3.6 V, with 5.5-V-tolerant inputs, 6.2-ns max propagation delay at 3.3 V, and AEC-Q100 qualified ESD protection (2000-V HBM). It serves as a level-translating address decoder in automotive body control modules.
For engineers reviewing the CLVC139AQPWRG4Q1 datasheet, CLVC139AQPWRG4Q1 pinout, CLVC139AQPWRG4Q1 application, or CLVC139AQPWRG4Q1 equivalent, key selection criteria include its dual-decoder architecture, 16-pin TSSOP package, 5.5-V input tolerance enabling mixed-voltage interfacing, and automotive-grade latch-up performance (>250 mA per JESD17).
Technical Context
This device integrates two independent 2-to-4 line decoders sharing no internal logic coupling-each features active-low enable (G), two select inputs (A, B), and four active-low outputs (Y0–Y3). All inputs are fully buffered, presenting only one normalized load to driving circuitry.
It supports true bidirectional voltage translation: inputs accept up to 5.5 V regardless of VCC (1.65–3.6 V), while outputs swing rail-to-rail between GND and VCC. Output drive strength is ±24 mA at 3.0 V, with guaranteed VOH ≥ 2.1 V and VOL ≤ 0.55 V under full load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 3.6 V - Enables direct integration into 1.8-V and 3.3-V automotive subsystems without level-shifting circuitry. |
| Input Voltage Tolerance | Up to 5.5 V - Allows direct connection to legacy 5-V microcontrollers or sensors without external clamping. |
| Max Propagation Delay | 6.2 ns at VCC = 3.3 V - Supports high-speed address decoding in real-time vehicle networks (e.g., LIN gateway arbitration). |
| Output Drive | ±24 mA at VCC = 3.0 V - Sufficient to directly drive LED indicators, small relays, or enable downstream logic gates. |
| AEC-Q100 Qualification | Grade 1 (−40°C to +125°C) - Certified for engine bay, transmission control, and ADAS sensor interface applications. |
| Latch-Up Immunity | >250 mA per JESD17 - Ensures robustness against transient ground bounce or supply rail disturbances in noisy automotive environments. |
| ESD Protection | 2000-V HBM, 200-V MM, 1000-V CDM - Meets stringent automotive ESD immunity requirements for in-vehicle assembly and field operation. |
Pinout & Package
TSSOP-16 (PW) package, 4.4 mm × 5.0 mm footprint, 1.2 mm max height, lead-free NiPdAu finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1G, 2G | Active-low enable input | Each controls one decoder independently; when high, all four outputs (Y0–Y3) go high-impedance (demux mode). |
| 1A, 1B / 2A, 2B | Binary select inputs | Two-bit address inputs per decoder; decode 00→Y0, 01→Y1, 10→Y2, 11→Y3 (all active-low outputs). |
| 1Y0–1Y3 / 2Y0–2Y3 | Active-low decoded outputs | Four dedicated outputs per decoder; asserted low per binary input combination when corresponding G is low. |
| VCC (Pin 16) | Power supply | Single 1.65–3.6-V supply powers both decoders; no separate IOVDD required. |
| GND (Pin 8) | Ground reference | Common return for all logic and output current paths; layout requires low-inductance connection to minimize ground bounce. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent decoders | Enables simultaneous decoding of two separate 2-bit address buses (e.g., front/rear door modules) in one package. |
| 5.5-V tolerant inputs | Eliminates need for external level shifters when interfacing with 5-V CAN transceivers or legacy MCU GPIOs. |
| Automotive temperature range | Guaranteed operation from −40°C to +125°C ambient - validated for under-hood and chassis-mounted ECUs. |
| Low dynamic power | ICC ≤ 10 µA at VCC = 3.6 V - reduces quiescent current in always-on vehicle subsystems (e.g., intrusion detection). |
| High noise immunity | VIL = 0.35×VCC (min), VIH = 0.65×VCC (min) - ensures reliable switching in electrically noisy automotive harness environments. |
Applications
| Body Control Module | Instrument Cluster Interface |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual decoder/demultiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC139AQPWRQ1 | Same silicon die, identical electrical specs, identical TSSOP-16 package; differs only in TI's internal assembly lot traceability and RoHS compliance documentation path. | No functional difference; used interchangeably in production where full AEC-Q100 retest documentation is not mandated. | Select CLVC139AQPWRG4Q1 when full TI G4-grade automotive qualification evidence (including extended reliability test reports) is contractually required. |
| MC74LCX139DTG | Lower VCC range (2.0–3.6 V), no 5.5-V input tolerance, rated only to +85°C ambient, non-AEC-Q100. | Suitable for industrial control panels but not certified for under-hood automotive deployment. | Choose MC74LCX139DTG only for cost-sensitive non-automotive applications where 5-V interface compatibility and −40°C operation are not needed. |
