Product details
Overview
74LV139DB,118 from NXP Semiconductors is a dual 2-to-4 line decoder/demultiplexer in SSOP16 package, operating from 1.0 V to 5.5 V supply, with active LOW enable inputs and mutually exclusive LOW-active outputs. It implements two independent decoders, each accepting binary address inputs (A0/A1) and driving four outputs (Y0–Y3), supporting both decoding and 1-to-4 demultiplexing functions in low-voltage embedded control logic.
For engineers reviewing the 74LV139DB,118 datasheet, 74LV139DB,118 pinout, 74LV139DB,118 application, or 74LV139DB,118 equivalent, this device is selected for voltage-flexible address decoding, bus routing, and enable-controlled signal distribution in industrial microcontroller peripherals, programmable logic interfaces, and multi-channel sensor multiplexing systems where TTL-level compatibility at 3.3 V and −40 °C to +125 °C operation are required.
Technical Context
The 74LV139DB,118 integrates two identical Si-gate CMOS decoder blocks, each with separate active LOW enable (nE) and two binary address inputs (nA0/nA1), producing four LOW-active outputs (nY0–nY3) that are mutually exclusive per decoder. Its architecture supports direct use as a 1-to-4 demultiplexer by routing data through the enable input while addressing via A0/A1.
It is functionally and pin-compatible with 74HC139 and 74HCT139 but optimized for 1.0 V–3.6 V operation, with guaranteed TTL input level acceptance at VCC = 2.7 V–3.6 V and characterized dynamic performance down to 1.2 V supply. Propagation delays range from 10 ns (typ, VCC = 3.3 V, CL = 15 pF) for address-to-output paths and 11 ns for enable-to-output paths.

|---|---|---|
| 1 | 1E | Active LOW enable for Decoder 1 - when HIGH, all Decoder 1 outputs forced HIGH (disabled state) |

| 3 | 1A1 | MSB address input for Decoder 1 - selects Y0/Y2 (A1 = 0) or Y1/Y3 (A1 = 1) |
| 4 | 1Y0 | LOW-active output for Decoder 1 - asserted when 1E = L, 1A1 = L, 1A0 = L |

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 |
|---|---|---|---|
| 74LV139D,118 | SO16 package (SOT109-1), 3.9 mm body width - larger footprint, lower thermal resistance than SSOP16 | Better suited for prototyping or high-reliability industrial boards requiring wider creepage/clearance | Select when mechanical robustness or reworkability outweighs board space constraints |
| SN74LV139ADBR | Texas Instruments variant; identical logic function and DC specs, but different AC characterization (tpd = 12 ns typ @ 3.3 V) | Validated for TI-specific reference designs and automotive AEC-Q100 Grade 2 qualification | Choose when sourcing from TI's authorized channels or aligning with TI-based platform designs |
Compared with 74LV139DB,118, the SO16 variant offers easier hand-soldering and higher power dissipation margin, while the TI SN74LV139ADBR provides alternate supply chain access and AEC-Q100 alignment - neither is pin-compatible without layout revision due to differing package dimensions and thermal pad presence.

FAQ
What is the minimum supply voltage for reliable operation of the 74LV139DB,118?
The 74LV139DB,118 is fully specified down to 1.0 V supply voltage, with static characteristics guaranteed across VCC = 1.0 V to 5.5 V. At 1.0 V, it operates with input levels referenced to GND or VCC, enabling ultra-low-power modes in battery-backed systems where the 74LV139DB,118 maintains functional decoding behavior without reset or latch-up.
Can the 74LV139DB,118 be used as a 1-to-4 demultiplexer?
Yes - the 74LV139DB,118 supports demultiplexing by using its active LOW enable input (1E or 2E) as the data input, while A0/A1 serve as select lines. When the enable is driven by a data signal and address lines configure the output path, the 74LV139DB,118 routes one input to exactly one of four LOW-active outputs, fulfilling standard 1-to-4 demux functionality without additional components.
Does the 74LV139DB,118 require external pull-up resistors on its outputs?
No - the 74LV139DB,118 outputs are push-pull CMOS drivers capable of actively driving HIGH or LOW. Pull-ups are unnecessary unless interfacing with open-drain buses or implementing wired-OR logic. The 74LV139DB,118's outputs source up to 6 mA at 3.0 V and sink up to 12 mA at 4.5 V, making external pull-ups redundant for standard CMOS loading.
How does the 74LV139DB,118 handle input transitions at different supply voltages?
The 74LV139DB,118 specifies maximum input transition rates: ≤500 ns/V below 2.0 V, ≤200 ns/V at 2.0–2.7 V, ≤100 ns/V at 2.7–3.6 V, and ≤50 ns/V above 3.6 V. These limits prevent false triggering from slow edges; for example, at VCC = 3.3 V, input rise/fall times must stay under 165 ns to ensure reliable decoding - a constraint directly enforced by the 74LV139DB,118's internal Schmitt-trigger-free input stage.
Is the SSOP16 package of the 74LV139DB,118 RoHS-compliant and lead-free?
Yes - the 74LV139DB,118 in SSOP16 (SOT338-1) package is manufactured per RoHS Directive 2011/65/EU and is lead-free, with matte tin (Sn) termination finish. Its JEDEC-standard footprint and thermal pad design support both automated reflow and hand-soldering processes compliant with IPC-J-STD-020 moisture sensitivity level (MSL) 1 requirements.
