Product details
Overview
74LV139PW,118 from NXP Semiconductors is a dual 2-to-4 line decoder/demultiplexer in TSSOP16 package, operating from 1.0 V to 5.5 V supply, with active LOW enable inputs and mutually exclusive LOW-active outputs. It delivers 11 ns typical propagation delay at 3.3 V (CL = 15 pF), supports TTL-level inputs at 2.7–3.6 V, and functions across −40 °C to +125 °C for industrial control and low-voltage logic routing.
For engineers reviewing the 74LV139PW,118 datasheet, 74LV139PW,118 pinout, 74LV139PW,118 application, or 74LV139PW,118 equivalent, this page provides verified functional identity, validated pin mapping, confirmed low-voltage timing behavior, real-world demultiplexing use cases, and two technically documented alternative parts for design flexibility.
Technical Context
The 74LV139PW,118 integrates two independent CMOS decoders, each accepting two binary address inputs (A0, A1) and driving four LOW-active outputs (Y0–Y3) with strict mutual exclusivity. Each decoder features a dedicated active LOW enable (E), allowing individual gating or combined operation as a 1-to-4 demultiplexer when E serves as data input.
Its Si-gate CMOS architecture ensures pin and functional compatibility with 74HC139 and 74HCT139 while optimizing for low-voltage operation down to 1.0 V. Input transition rate limits (e.g., 100 ns/V at 2.7–3.6 V) and ground bounce < 0.8 V at 3.3 V define its signal integrity envelope in noise-sensitive systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.0 V to 5.5 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters |
| Propagation delay (A→Y) | 11 ns typical at VCC = 3.3 V, CL = 15 pF - supports ≥45 MHz address decoding in synchronous systems |
| Output drive strength | ±6 mA at 3.0 V (VOH/VOL), ±12 mA at 4.5 V - sufficient to drive multiple 74LVC inputs or small capacitive loads |
| Input voltage thresholds | VIH = 2.0 V, VIL = 0.8 V at VCC = 3.3 V - compatible with TTL outputs and robust against noise margins |
| Operating temperature | −40 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and extended-range embedded applications |
| ESD protection | HBM > 2000 V, MM > 200 V - meets IEC61000-4-2 Level 2 for board-level handling and system integration |
Pinout & Package
TSSOP16 package: plastic thin shrink small outline, 16 leads, body width 4.4 mm, 0.65 mm pitch, lead-free and RoHS compliant per SOT403-1 outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (1E) | Decoder 1 enable input | Active LOW gate controlling all Y0–Y3 outputs of first decoder; HIGH forces all outputs HIGH |
| 2 (1A0), 3 (1A1) | Decoder 1 address inputs | Binary-weighted inputs selecting one of four LOW outputs (Y0–Y3); LSB/MSB ordering per truth table |
| 4–7 (1Y0–1Y3) | Decoder 1 outputs | Mutually exclusive, open-drain compatible LOW-active outputs; sink current up to 6 mA at 3 V |
| 8 (GND) | Ground reference | Primary return path for all internal logic and output currents; must be low-impedance connection |
| 9–12 (2Y3–2Y0) | Decoder 2 outputs | LOW-active outputs for second decoder; pin order reversed (Y3 to Y0) per physical layout in TSSOP |
| 13 (2A1), 14 (2A0) | Decoder 2 address inputs | Independent binary address pair for second decoder; identical function to pins 2–3 but isolated circuitry |
| 15 (2E) | Decoder 2 enable input | Separate active LOW control for second decoder; allows asynchronous enable/disable of each decoder |
| 16 (VCC) | Supply voltage | Single positive rail powering both decoders; bypass capacitor (100 nF) required near pin for stable switching |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent decoders | Enables simultaneous 2-to-4 decoding of separate address buses-e.g., memory bank selection and peripheral decode in same IC |
| Demultiplexing capability | Each enable input doubles as data input, converting decoder into 1-to-4 demux without external gates |
| Wide voltage operation (1.0–5.5 V) | Eliminates need for separate voltage translators in mixed-supply systems such as battery-powered IoT nodes with 1.8 V MCU and 3.3 V sensors |
| Active LOW mutually exclusive outputs | Ensures only one output asserts per decoder cycle-critical for enabling single peripherals in bus arbitration or LED matrix row/column drivers |
| TTL-input compatibility (2.7–3.6 V) | Direct interfacing with legacy 74LS/74ALS outputs without pull-ups or level shifters in industrial retrofits |
Applications
| Memory Address Decoding | Peripheral Select Logic |
|---|---|
Use Scenario: Selecting among four SRAM banks or flash memory segments using 2-bit address lines. IC Role / Device Role / Timing Role: Dual decoder maps A0/A1 to four chip-select signals (CS0–CS3), with independent enables permitting dynamic bank isolation. Use Value: Reduces PCB footprint vs. discrete gates; 11 ns delay ensures setup/hold compliance with 25 MHz memory clocks. |
Use Scenario: Routing SPI or UART signals to one of four sensor modules based on host command. IC Role / Device Role / Timing Role: Acts as addressable switch-host writes address bits and pulses enable to activate target peripheral's CS line. Use Value: Eliminates microcontroller GPIO overhead; LOW-active outputs directly drive standard active-low CS inputs. |
| LED Matrix Row Driver | Industrial I/O Expansion |
Use Scenario: Scanning 4×N LED matrix by sequentially activating rows while column data is latched. IC Role / Device Role / Timing Role: Generates row-select pulses (Y0–Y3) synchronized to display refresh clock; each output sinks row current. Use Value: Built-in mutual exclusivity prevents ghosting; 6 mA drive supports common-anode matrices up to 16 LEDs per row. |
Use Scenario: Expanding digital I/O count for PLC backplane where 2-bit DIP switch sets module ID (0–3). IC Role / Device Role / Timing Role: Converts DIP switch state into one asserted enable line for corresponding I/O expander IC. Use Value: Enables hot-swappable module addressing without firmware reconfiguration; operates reliably at −40 °C to +125 °C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-to-4 decoder/demultiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC139PW,118 | Higher drive (±24 mA), 1.65–3.6 V only, faster tpd (5.5 ns @ 3.3 V) | Requires tighter VCC control; unsuitable for 5 V or sub-1.65 V systems where 74LV139PW,118 operates | Choose for speed-critical 3.3 V-only designs needing stronger fanout |
| SN74LV139ADBR | TSSOP16, −40 °C to +125 °C, identical VCC range and pinout, TI-sourced | No functional deviation; differs only in manufacturer qualification and traceability documentation | Choose for dual-sourcing or TI-aligned BOMs without redesign |
Compared with 74LV139PW,118, the 74LVC139PW,118 trades wider voltage support for higher speed and drive, while SN74LV139ADBR offers identical electrical and mechanical behavior with alternate supply-chain assurance-both require no PCB changes but differ in qualification scope and thermal derating curves.

FAQ
What is the absolute maximum supply voltage for the 74LV139PW,118?
The 74LV139PW,118 has an absolute maximum supply voltage (VCC) of +7.0 V, as specified in Table 4 of the NXP datasheet. However, recommended operation is limited to 1.0 V to 5.5 V. Exceeding 7.0 V risks permanent damage per IEC 60134 limiting values, and operation above 5.5 V voids guaranteed functionality-even if within absolute max ratings.
Does the 74LV139PW,118 support 1.2 V logic operation with full timing guarantees?
Yes, the 74LV139PW,118 is fully characterized down to 1.2 V, with propagation delay specified at 70 ns (typical) and static parameters guaranteed across −40 °C to +125 °C. The datasheet explicitly states LV devices function down to 1.0 V (with VI = GND or VCC), though timing specs are only published from 1.2 V onward.
Can the 74LV139PW,118 be used as a 1-to-4 demultiplexer, and how is that configured?
Yes, the 74LV139PW,118 can operate as a 1-to-4 demultiplexer. Connect the data signal to either 1E or 2E (active LOW enable), apply address bits to the corresponding A0/A1 inputs, and use Y0–Y3 as outputs. When E is LOW, the selected Yn goes LOW; all others remain HIGH-effectively routing one input to one of four paths.
Is the 74LV139PW,118 pin-compatible with the 74HC139 in TSSOP16 package?
No-the 74HC139 is not offered in TSSOP16 by NXP; its standard packages are SO16 and DIP16. While the 74LV139PW,118 is functionally and logically pin-compatible with 74HC139/74HCT139 *at the logic level*, physical pin mapping matches only within the same package variant (e.g., SO16-to-SO16). TSSOP16 pinout is unique to LV-series variants like 74LV139PW,118.
What is the maximum capacitive load the 74LV139PW,118 outputs can drive while maintaining specified timing?
The 74LV139PW,118 propagation delay is specified with CL = 15 pF (Table 7), and dynamic characteristics assume ≤50 pF load (CPD test condition). Driving >50 pF increases tpd nonlinearly and may cause VOH/VOL degradation. For loads >30 pF, add series termination or buffer stages to maintain timing integrity and signal fidelity.
