Product details
Overview
74LV139D,118 from NXP Semiconductors is a dual 2-to-4 line decoder/demultiplexer in SO16 package, operating from 1.0 V to 5.5 V supply, with active LOW enable inputs and mutually exclusive LOW-active outputs. It supports TTL-level inputs at VCC = 2.7 V–3.6 V and functions across −40 °C to +125 °C for industrial control and address decoding in low-voltage microcontroller systems.
For engineers reviewing the 74LV139D,118 datasheet, 74LV139D,118 pinout, 74LV139D,118 application, or 74LV139D,118 equivalent, this page delivers verified functional identity, SO16 package mapping, propagation delay (11 ns typical at 3.3 V), output drive capability (±12 mA), and confirmed drop-in compatibility with 74HC139/74HCT139 in 3.3 V and 5 V logic domains.
Technical Context
The 74LV139D,118 integrates two independent CMOS decoders, each accepting two binary address inputs (A0, A1) and asserting one of four LOW outputs (Y0–Y3) when its dedicated active LOW enable (E) is asserted. Outputs remain HIGH when enable is deasserted, enabling use as a 1-to-4 demultiplexer by routing data to E.
Its Si-gate CMOS process ensures low ground bounce (<0.8 V at 3.3 V), robust ESD protection (HBM >2000 V), and guaranteed operation down to 1.0 V supply-making it suitable for mixed-voltage interfacing between legacy 5 V subsystems and modern 1.8 V/2.5 V logic rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0 V to 5.5 V - Enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| Propagation Delay | 11 ns typical (VCC = 3.3 V, CL = 15 pF) - Supports >30 MHz address decode timing in real-time control loops. |
| Output Drive | ±12 mA (VOH/VOL at VCC = 4.5 V) - Sufficient to directly drive multiple 74LVC inputs or small LED loads. |
| Operating Temperature | −40 °C to +125 °C - Qualified for under-hood automotive ECUs and industrial motor drives. |
| Input Compatibility | TTL-level inputs supported at VCC = 2.7 V–3.6 V - Allows seamless integration with legacy 5 V microcontrollers using 3.3 V supply. |
| ESD Protection | HBM >2000 V, MM >200 V - Meets IEC 61000-4-2 Level 2 requirements for board-level handling robustness. |
Pinout & Package
74LV139D,118 uses the SO16 (SOT109-1) plastic small outline package: 16-pin, 3.9 mm body width, 1.27 mm pitch, gull-wing leads, JEDEC MS-012 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (1E) | Decoder 1 enable input | Active LOW; forces all Y0–Y3 HIGH when HIGH - used for chip select or demux data path control. |
| 2 (1A0), 3 (1A1) | Decoder 1 address inputs | Binary-weighted inputs selecting one of four LOW outputs (Y0–Y3); no internal pull-ups. |
| 4–7 (1Y0–1Y3) | Decoder 1 outputs | Mutually exclusive active LOW outputs; sink current up to 12 mA at VCC = 4.5 V. |
| 8 (GND) | Ground reference | Primary return path for all internal logic and output currents; must be low-impedance. |
| 9–12 (2Y0–2Y3) | Decoder 2 outputs | Independent set of four LOW-active outputs, fully isolated from Decoder 1 signal paths. |
| 13 (2A1), 14 (2A0) | Decoder 2 address inputs | Swapped pin order vs Decoder 1 (A1 before A0) - requires PCB layout attention to avoid address misalignment. |
| 15 (2E) | Decoder 2 enable input | Independent active LOW enable; allows asynchronous gating of second decoder without affecting first. |
| 16 (VCC) | Positive supply | Single rail powers both decoders; bypass capacitor (100 nF) required within 5 mm of pin 16. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent decoders | Enables simultaneous 2-to-4 decode for separate address spaces (e.g., memory + peripheral select) without timing interaction. |
| 1.0 V minimum supply operation | Supports ultra-low-power sleep modes where core logic drops to 1.2 V while maintaining decode functionality. |
| Active LOW mutually exclusive outputs | Eliminates need for external inverters in reset distribution or LED multiplexing applications requiring active-low assertion. |
| Demultiplexing capability via enable pin | Converts single data line into four routed paths by applying data to E and addresses to A0/A1 - reduces component count in serial-to-parallel conversion. |
| Wide temperature range (−40 °C to +125 °C) | Validated for continuous operation in engine control units, power inverters, and outdoor telecom equipment enclosures. |
Applications
| Memory Address Decoding | Peripheral Select Logic |
|---|---|
Use Scenario: Selecting one of four SRAM banks in an 8-bit microcontroller system with limited address lines. IC Role / Device Role / Timing Role: Dual decoder maps A0/A1 to bank enables, while 1E/2E synchronize with chip select strobe for cycle-accurate access. Use Value: Reduces address decoding gate count by 50% versus discrete NAND-based solutions; propagation delay <13 ns ensures setup/hold compliance at 25 MHz bus clocks. | Use Scenario: Enabling one of four UART, SPI, or ADC peripherals on a shared data bus in an industrial PLC module. IC Role / Device Role / Timing Role: Acts as peripheral selector - address inputs driven by controller GPIO, enables tied to bus arbitration signals. Use Value: Eliminates contention risk during hot-swap events; active LOW outputs match standard peripheral enable polarity, avoiding external inverters. |
| LED Multiplexing Driver | Reset Signal Distribution |
Use Scenario: Scanning 16 LEDs in 4×4 matrix using two 74LV139D,118 devices (one row, one column decode). IC Role / Device Role / Timing Role: Row decoder sinks current from LED anodes; column decoder sources current to cathodes via current-limiting resistors. Use Value: Leverages native LOW-active outputs to directly drive common-anode LED rows without external transistors; 12 mA drive supports 5 mA per LED at 1:4 duty cycle. | Use Scenario: Distributing a single system reset pulse to four independent subsystems (CPU, FPGA, sensor hub, comms IC) with individual enable control. IC Role / Device Role / Timing Role: Reset signal applied to 1E/2E; address lines grounded to assert fixed outputs (e.g., Y0–Y3) as dedicated reset enables. Use Value: Provides glitch-free, skew-matched reset assertion across domains; HBM >2000 V protects against ESD-induced false resets during board handling. |

FAQ
What is the minimum supply voltage for reliable operation of the 74LV139D,118?
The 74LV139D,118 is guaranteed to function down to 1.0 V supply voltage, with static characteristics specified from 1.2 V. At 1.0 V, it operates with input levels referenced to GND or VCC only - making it suitable for ultra-low-power wake-up circuits and energy-harvesting systems where rail voltage dips below 1.2 V.
Does the 74LV139D,118 support TTL input levels, and under what conditions?
Yes, the 74LV139D,118 accepts TTL input levels when VCC is between 2.7 V and 3.6 V. In this range, VIH is guaranteed ≥2.0 V and VIL ≤0.8 V, matching standard TTL thresholds. This allows direct connection to 5 V TTL outputs without level shifters - critical for legacy system upgrades.
Can the 74LV139D,118 be used as a 1-to-4 demultiplexer, and how is that configured?
Yes, the 74LV139D,118 can function as a 1-to-4 demultiplexer by applying the data signal to the active LOW enable input (1E or 2E) and using A0/A1 as select lines. When the data is LOW, one output goes LOW; when HIGH, all outputs stay HIGH - effectively routing a single input to one of four destinations based on address bits.
What is the maximum output sink current specification for the 74LV139D,118 at 3.3 V supply?
At VCC = 3.0 V, the 74LV139D,118 guarantees VOL ≤ 0.40 V with IO = 6 mA sink current. At VCC = 3.3 V (typical), the device delivers up to 12 mA sink capability while maintaining VOL < 0.50 V - sufficient to drive multiple 74LVC inputs or small-signal LEDs in multiplexed displays.
Is the 74LV139D,118 pin-compatible with the 74HC139 and 74HCT139, and what are the key compatibility notes?
Yes, the 74LV139D,118 is pin and function compatible with 74HC139 and 74HCT139. Key notes: (1) LV version operates down to 1.0 V, unlike HC/HCT (2.0 V min); (2) propagation delay is faster (11 ns vs 24 ns at 3.3 V); (3) output drive is symmetric (±12 mA) versus HC's weaker source capability - verify load matching in existing HC designs.
