Product details

Overview

74LVC2G125GS,115 from NXP Semiconductors is a dual non-inverting bus buffer with 3-state outputs, designed for voltage-level translation between 1.65 V and 5.5 V logic domains. It features ±24 mA output drive, 3.7 ns typical propagation delay at 3.3 V, and operates across -40 °C to +125 °C. Used in I²C bus isolation and low-voltage microcontroller peripheral interfacing.

For engineers reviewing the 74LVC2G125GS,115 datasheet, 74LVC2G125GS,115 pinout, 74LVC2G125GS,115 application, or 74LVC2G125GS,115 equivalent, key selection criteria include bidirectional level-shifting capability, rail-to-rail input tolerance, guaranteed 3-state timing, and XSON-8 package thermal performance in space-constrained PCB layouts.

Technical Context

This device integrates two independent non-inverting buffers, each with separate output-enable (OE) control. Each channel supports mixed-voltage operation: inputs tolerate up to 5.5 V regardless of supply voltage (V_CC = 1.65–5.5 V), and outputs swing rail-to-rail.

The 3-state outputs exhibit symmetrical rise/fall times (< 3.0 ns at V_CC = 3.3 V), and the device meets AEC-Q100 Grade 1 reliability requirements for automotive under-hood applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65 V to 5.5 V - enables interoperability between 1.8 V, 2.5 V, 3.3 V, and 5 V logic systems
Propagation Delay	3.7 ns (typ) at V_CC = 3.3 V - supports >100 MHz data rates in buffered control lines
Output Drive	±24 mA - drives standard CMOS loads and short PCB traces without external termination
Input Voltage Tolerance	0 V to 5.5 V independent of V_CC - allows safe connection to higher-voltage buses while powered from lower V_CC
Operating Temperature	−40 °C to +125 °C - qualified for automotive engine-control and industrial motor-drive environments
ESD Rating	HBM ±4 kV - protects against handling-induced discharge during assembly and field service

Pinout & Package

XSON-8 (2.0 × 1.25 mm, 0.5 mm pitch) thermally enhanced leadless package with exposed die pad for improved PCB heat dissipation in high-density layouts.

Pin/Terminal	Circuit Role	Design Meaning
1, 5	Input (A1, A2)	CMOS-compatible input with 5.5 V tolerant structure
2, 6	Output Enable (OE1, OE2)	Active-low control: OE = LOW enables output; OE = HIGH forces high-impedance state
3, 7	Output (Y1, Y2)	Push-pull output with ±24 mA drive and rail-to-rail swing
4	GND	Ground reference for all internal circuitry and ESD protection network
8	V_CC	Supply voltage input; powers internal logic and output stage

Key Features

Feature	Design Value
5.5 V tolerant inputs	Enables direct connection to legacy 5 V buses without external level shifters
Independent 3-state control per channel	Allows dynamic bus arbitration and partial system power-down without signal contention
Low dynamic power consumption	Typical ICC = 10 µA at 3.3 V - reduces quiescent load on battery-backed subsystems
AEC-Q100 Grade 1 qualification	Validated for automotive applications requiring −40 °C to +125 °C operation and robust EMC immunity

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
SN74LVC2G125DBVR	SOT-23-8 package; 0.65 mm pitch; higher thermal resistance (θ_JA = 278 °C/W vs. 190 °C/W)	Less suitable for high-density, thermally constrained layouts	Prefer when board rework accessibility or legacy footprint compatibility is prioritized over thermal performance
74LVC2G126GS,115	Inverting logic function instead of non-inverting; identical pinout, specs, and package	Requires logic inversion in signal path; unsuitable where polarity must be preserved	Select only if system-level signal inversion is acceptable or compensated elsewhere in firmware/hardware

Compared with SN74LVC2G125DBVR, the 74LVC2G125GS,115 offers superior thermal dissipation in compact designs; versus 74LVC2G126GS,115, it preserves signal polarity critical for control-line buffering without additional logic gates.

FAQ

Is the 74LVC2G125GS,115 suitable for bidirectional I²C signal buffering?

No - it is unidirectional (non-inverting buffer only). For true bidirectional I²C buffering, NXP recommends the PCA9306 or NXPI's dedicated I²C bus buffer family. The 74LVC2G125GS,115 can isolate one-directional control signals on I²C systems (e.g., reset or interrupt lines) but cannot pass SDA/SCL bidirectionally without external direction control logic.

What is the maximum recommended trace length for outputs driving 50 pF loads?

At V_CC = 3.3 V, with 50 pF capacitive load, the 74LVC2G125GS,115 maintains signal integrity up to 8 cm (3.1 in) of 50 Ω microstrip trace. Longer traces require series termination or reduced load capacitance to avoid overshoot/undershoot exceeding ±10 % of V_CC.

Does the device support hot insertion or live bus connection?

Yes - its 5.5 V tolerant inputs and powered-off protection (I_OFF specification) allow safe connection to live buses while V_CC is unpowered. Input clamping diodes limit current to < 100 µA under overvoltage conditions, preventing damage during hot-plug events in modular backplane systems.

How does the XSON-8 package affect thermal performance in continuous operation?

The XSON-8's exposed die pad lowers junction-to-board thermal resistance to 190 °C/W. At 24 mA output drive and 3.3 V supply, junction temperature rise remains < 15 °C above ambient in still air - enabling continuous operation without derating up to +105 °C ambient in properly designed PCB layouts with ≥2 oz copper and thermal vias.
