Product details
Overview
SN74LVC2G125YEAR from Texas Instruments is a dual 3-state bus buffer gate operating from 1.65 V to 5.5 V, featuring two independent noninverting buffers with active-low output-enable controls (1OE, 2OE), ±24-mA drive at 3.3 V, 4.3-ns max propagation delay at 3.3 V, and Ioff support for live insertion in partial-power-down systems. It enables bidirectional signal isolation in high-speed data acquisition and SSD interconnects.
For engineers reviewing the SN74LVC2G125YEAR datasheet, SN74LVC2G125YEAR pinout, SN74LVC2G125YEAR application, or SN74LVC2G125YEAR equivalent, key selection criteria include 5.5-V tolerant inputs for level translation, low ICC (10 µA max), balanced push-pull outputs, thermal performance in DSBGA packaging, and compatibility with industrial temperature range (–40°C to +125°C) designs.
Technical Context
The SN74LVC2G125YEAR implements two independent noninverting buffer functions (Y = A) with separate active-low output-enable inputs (1OE, 2OE). Each buffer drives high-impedance (Z) when its OE is high, enabling bus sharing and signal gating in multi-drop configurations.
It uses standard CMOS inputs with overvoltage tolerance up to 5.5 V, supports partial-power-down via Ioff circuitry that limits leakage to ±10 µA when VCC = 0 V, and features balanced push-pull outputs capable of sourcing/sinking identical currents-critical for clean edge integrity in high-speed routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - Enables single-supply operation across 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains. |
| Max Propagation Delay | 4.3 ns at VCC = 3.3 V, TA = –40°C to +85°C - Supports >100-MHz signal routing in data acquisition paths. |
| Output Drive | ±24 mA at VCC = 3.3 V - Sufficient to drive multiple CMOS loads or moderate capacitive traces without external buffering. |
| Ioff Leakage | ±10 µA max at VCC = 0 V - Prevents back-current damage during hot-plug or staggered power sequencing. |
| Input Voltage Tolerance | Up to 5.5 V regardless of VCC - Allows down-translation from 5-V peripherals to 3.3-V or 1.8-V subsystems. |
| ESD Rating | 2000-V HBM, 1000-V CDM - Meets industrial handling requirements without additional protection circuitry. |
| Operating Temperature | –40°C to +125°C - Qualified for under-hood automotive, industrial motor control, and military radar environments. |
Pinout & Package
SN74LVC2G125YEAR is packaged in an 8-pin DSBGA (YZP) measuring 1.91 mm × 0.91 mm, optimized for space-constrained portable and embedded applications. The die-size package eliminates leadframe parasitics and improves thermal resistance (RθJA = 99.8°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Input of Buffer 1 | Noninverting data input; accepts 0–5.5 V signals independent of VCC level. |
| 2A | Input of Buffer 2 | Independent noninverting input; enables dual-channel signal conditioning or isolation. |
| 1OE | Active-Low Output Enable for Buffer 1 | Pulling high disables 1Y output into high-impedance state; requires pullup resistor during power-up. |
| 2OE | Active-Low Output Enable for Buffer 2 | Independent control allows time-multiplexed or conditional activation of second buffer path. |
| 1Y | Output of Buffer 1 | 3-state CMOS output with ±24-mA drive; clamped diodes protect against negative transients. |
| 2Y | Output of Buffer 2 | Electrically isolated output path; supports separate load termination and routing. |
| GND | Ground Reference | Return path for all internal logic and I/O; must be low-inductance connection in high-speed layouts. |
| VCC | Positive Supply | Single supply pin powering both buffers; bypass capacitor (0.1 µF) required adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ DSBGA Packaging | Dies-as-package construction reduces footprint by >50% vs. VSSOP, eliminates bond wire inductance, and improves signal integrity. |
| Ioff Partial-Power-Down Support | Enables safe insertion into live backplanes or hot-swap modules without damaging current backflow. |
| 5.5-V Tolerant Inputs | Eliminates need for external level shifters when interfacing legacy 5-V sensors or controllers to modern low-voltage SoCs. |
| Balanced Push-Pull Outputs | Ensures matched rise/fall times (<10% skew) critical for minimizing jitter in clock distribution or data strobe paths. |
| Low ICC Quiescent Current | 10 µA max enables use in battery-backed or always-on monitoring circuits without compromising runtime. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G126YEAR | Inverting output logic (Y = NOT A); identical VCC range, drive strength, and package options. | Suitable where signal polarity inversion is required in bus arbitration or enable logic chains. | Select SN74LVC2G126YEAR only when functional inversion is needed; otherwise SN74LVC2G125YEAR maintains direct signal mapping. |

FAQ
What is the maximum operating temperature for SN74LVC2G125YEAR?
The SN74LVC2G125YEAR is rated for continuous operation from –40°C to +125°C ambient temperature, meeting industrial and extended-temperature requirements for applications such as motor control, radar, and SSDs. This rating is validated per JEDEC JESD22-A108 and confirmed in the device's Recommended Operating Conditions table.
Does SN74LVC2G125YEAR support level translation between different supply voltages?
Yes, SN74LVC2G125YEAR supports down-translation: its inputs tolerate up to 5.5 V regardless of VCC level, allowing 5-V signals to safely drive the device while VCC operates at 1.8 V, 2.5 V, or 3.3 V. This eliminates external level shifters in mixed-voltage systems like SSD controllers interfacing with legacy peripherals.
How does the Ioff feature benefit system design with SN74LVC2G125YEAR?
The Ioff feature in SN74LVC2G125YEAR disables outputs and limits input/output leakage to ±10 µA when VCC = 0 V, enabling safe live insertion into powered-backplane systems and preventing damaging back-current during partial power-down sequences-critical for hot-swap SSD modules and modular radar subsystems.
What is the recommended bypass capacitor for SN74LVC2G125YEAR?
A 0.1-µF ceramic capacitor placed as close as possible to the VCC pin is recommended for SN74LVC2G125YEAR. For systems with multiple supply domains or high noise susceptibility, paralleling with a 1-µF capacitor further suppresses broadband switching noise and stabilizes rail integrity during fast output transitions.
Can SN74LVC2G125YEAR drive multiple CMOS loads simultaneously?
Yes, SN74LVC2G125YEAR can drive multiple CMOS loads: its ±24-mA output drive at 3.3 V exceeds typical CMOS input current requirements (≤1 µA), supporting fan-out to ≥10 standard CMOS inputs. However, total capacitive load should remain ≤50 pF to maintain 4.3-ns propagation delay and avoid signal ringing.
