Product details

Overview

74LVC2G125GD,125 from NXP Semiconductors is a dual non-inverting 3-state buffer with 1.65 V to 5.5 V supply range, ±24 mA output drive, and 3.7 ns typical propagation delay at 3.3 V. It operates in industrial temperature range (−40 °C to +125 °C) and is used in voltage-level translated data bus isolation for mixed-voltage microcontroller interfaces.

For engineers reviewing the 74LVC2G125GD,125 datasheet, 74LVC2G125GD,125 pinout, 74LVC2G125GD,125 application, or 74LVC2G125GD,125 equivalent, key selection criteria include bus hold immunity, power supply voltage compatibility across 1.8 V/3.3 V/5 V domains, and guaranteed 3-state leakage current below 10 µA.

Technical Context

This device implements two independent non-inverting buffers, each with separate 3-state control (1OE, 2OE) enabling bidirectional bus isolation. Each channel supports I_OH/I_OL = ±24 mA at V_CC = 3.3 V and exhibits rail-to-rail input switching thresholds (V_IH = 0.7×V_CC, V_IL = 0.3×V_CC).

Designed for low-voltage CMOS logic interfacing, it features ESD protection exceeding 4 kV HBM and operates with static power dissipation under 10 µA at 25 °C. The input structure tolerates voltages up to 5.5 V regardless of V_CC level, supporting true overvoltage-tolerant operation.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.65 V to 5.5 V - enables interoperability across 1.8 V, 3.3 V, and 5 V logic domains without level shifters
Propagation Delay	3.7 ns @ V_CC = 3.3 V - supports >100 MHz data rates in buffered address/data paths
Output Drive	±24 mA @ V_CC = 3.3 V - drives 15 pF loads with <10% overshoot and clean edge integrity
3-State Leakage	<10 µA @ V_CC = 3.3 V - prevents unintended bus loading during high-impedance state
Input Overvoltage Tolerance	Up to 5.5 V independent of V_CC - allows safe connection to higher-voltage peripherals without external clamping
Operating Temperature	−40 °C to +125 °C - qualified for under-hood automotive and industrial control environments

Pinout & Package

Supplied in ultra-small 8-pin XSON8 (2 × 1.35 mm, 0.5 mm pitch) package with wettable flank terminations for automated optical inspection.

Pin/Terminal	Circuit Role	Design Meaning

2 (1Y)	Channel 1 Output	Active-high non-inverting output with 3-state capability controlled by pin 3
3 (1OE)	Channel 1 Output Enable	Active-low enable; pulls output to high-impedance when logic high
4 (GND)	Ground Reference	Primary return path for all internal logic and I/O current
5 (2OE)	Channel 2 Output Enable	Independent active-low enable for second buffer channel
6 (2Y)	Channel 2 Output	Active-high non-inverting output with 3-state capability controlled by pin 5
7 (2A)	Channel 2 Input	Second independent CMOS input with identical voltage tolerance as pin 1
8 (V_CC)	Power Supply	Single supply input supporting 1.65–5.5 V; powers both channels and I/O structures

Key Features

Feature	Design Value
Overvoltage-tolerant inputs	Accepts up to 5.5 V on any input while V_CC = 1.65 V - eliminates need for external voltage translators in mixed-supply systems
Low dynamic power consumption	Typical I_CC = 10 µA at 25 °C and DC - reduces quiescent current in always-on interface circuits
Guaranteed 3-state off-leakage	<10 µA max at V_CC = 3.3 V and T_A = 125 °C - ensures reliable bus release in hot industrial environments
Wettable flank package	XSON8 with side-wettable flanks - enables automated AOI verification of solder joint quality in high-reliability PCB assembly

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
SN74LVC2G125DPWR	Same logic function but in 8-pin USON package (2 × 2 mm); slightly higher propagation delay (4.2 ns)	Larger footprint and no wettable flanks - less suitable for AOI-critical automotive production	Preferred where board space permits and optical inspection is not required
74AUP2G125GW,125	Lower static current (0.5 µA), wider V_CC range (0.8–3.6 V), but max V_IN = 3.6 V - no 5 V tolerance	Not suitable for 5 V peripheral interfacing; limited to sub-3.6 V systems only	Select only for ultra-low-power battery-operated devices with no overvoltage requirement

Compared with SN74LVC2G125DPWR and 74AUP2G125GW,125, the 74LVC2G125GD,125 uniquely combines 5.5 V input tolerance, wettable flank packaging, and industrial temperature rating - making it optimal for mixed-voltage automotive and industrial bus isolation where reliability and manufacturability are critical.

FAQ

Is the 74LVC2G125GD,125 compatible with 1.8 V microcontrollers?

Yes. Its 1.65 V minimum supply voltage and rail-to-rail input thresholds (V_IL = 0.3×V_CC, V_IH = 0.7×V_CC) ensure reliable recognition of 1.8 V logic levels. Inputs tolerate up to 5.5 V regardless of V_CC, allowing safe connection to higher-voltage peripherals without external components.

Does this device support hot insertion or live bus connection?

No. While inputs are overvoltage-tolerant, the device lacks powered-off protection (I_OFF) or bus-hold functionality. Connecting to an active bus while V_CC is unpowered may cause latch-up or excessive current flow. Power sequencing must ensure V_CC is stable before applying input signals.

What is the maximum capacitive load this buffer can drive reliably?

It is characterized to drive up to 15 pF loads with specified propagation delay and output rise/fall times. Driving >15 pF increases delay nonlinearly and may degrade edge monotonicity. For heavier loads, add series termination or use higher-drive variants like 74LVC2G241.

Can both output enables be tied together for synchronized control?

Yes. Pins 3 (1OE) and 5 (2OE) are electrically independent but share identical logic behavior (active-low). They may be connected to a single controller GPIO or pull-up/pull-down network to enable/disable both channels simultaneously without timing skew or functional conflict.
