Product details

Overview

74V2G07STR from STMicroelectronics is a triple non-inverting buffer with open-drain outputs, designed for level-shifting and wired-OR logic interfacing between 5V and 3V systems. Confirmed parameters: tPD = 3.7 ns (typ. at VCC = 5V), ICC ≤ 1 µA (max. at TA = 25°C), VCC operating range 2V–5.5V, input tolerance up to 7V independent of supply, and high noise immunity (VNIH/VNIL ≥ 28% VCC). It is used in I²C bus pull-up interfaces and mixed-voltage GPIO expansion.

For engineers reviewing the 74V2G07STR datasheet, 74V2G07STR pinout, 74V2G07STR application, or 74V2G07STR equivalent, key selection criteria include open-drain drive capability, input overvoltage tolerance, propagation delay across voltage rails, and SOT23-8L thermal and routing constraints in space-constrained PCBs.

Technical Context

The 74V2G07STR implements three independent CMOS buffer stages with open-drain outputs, enabling wired-AND/wired-OR bus topologies. Each channel accepts inputs from 0V to 7V regardless of VCC, supporting robust level translation without external biasing.

Its sub-micron C2MOS process delivers latch-up immunity per JEDEC JESD78, and power-down protection ensures safe operation during supply sequencing or brown-out. Output leakage (IOZ ≤ ±5 µA at VCC = 5.5V) and low input leakage (II ≤ ±1 µA) maintain signal integrity in high-impedance bus environments.

Key Specifications

Parameter	Value and Actual Design Meaning
tPD	3.7 ns typical at VCC = 5V, CL = 15 pF - enables >100 MHz toggle rates in fast digital control paths
VCC Range	2.0 V to 5.5 V - supports single-supply operation across 3.3V and 5V logic domains
Input Voltage Range	-0.5 V to +7.0 V - allows direct connection to higher-voltage signals without clamping diodes
VOL @ IO = 8 mA	≤ 0.55 V at VCC = 4.5 V - ensures reliable LOW-state recognition under full load on I²C/SMBus lines
ICC (Quiescent)	≤ 1 µA max at TA = 25°C - minimizes standby power in battery-backed or always-on interface circuits
VIH/VIL	0.7VCC / 0.3VCC thresholds - provides rail-proportional noise margins across operating voltages
CIN / COUT	≤ 10 pF each - limits capacitive loading on driving sources and preserves signal edge integrity

Pinout & Package

SOT23-8L package: 1.45 mm height, 3.00 mm × 3.00 mm footprint, 0.65 mm pitch, thermally enhanced for surface-mount reliability in compact industrial and portable designs.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 6	1A, 2A, 3A - Input terminals	Accept 0–7V logic signals; internally protected against overvoltage and reverse current
2, 5, 7	3Y, 2Y, 1Y - Open-drain output terminals	Require external pull-up; sink up to 8 mA while maintaining VOL ≤ 0.55 V
4	GND - Ground reference	Common return path for all internal circuitry and output current sinking
8	VCC - Positive supply	Supplies internal logic; decoupling capacitor required within 5 mm for stable AC performance

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar open-drain buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC2G07DBVR	Lower VCC min (1.65V), higher max ICC (10 µA), no 7V input tolerance	Optimized for ultra-low-voltage 1.8V/2.5V systems; unsuitable for 5V-tolerant interfacing	Select when operating below 2V or requiring AEC-Q100 qualification
NC7WZ07P6X	Higher tPD (9.5 ns typ.), no specified 7V input rating, smaller SOT-363 package	Better suited for space-constrained consumer PCBs where speed <10 MHz suffices	Select when board area is critical and propagation delay >7 ns is acceptable

Compared with SN74LVC2G07DBVR and NC7WZ07P6X, the 74V2G07STR uniquely combines 7V input tolerance, sub-4ns propagation, and SOT23-8L thermal robustness - making it optimal for industrial and automotive voltage-bridging where reliability trumps minimal footprint.

FAQ

Can the 74V2G07STR be used with a 1.8V supply?

No. The recommended operating VCC range is 2.0 V to 5.5 V per datasheet Section "Recommended Operating Conditions". At 1.8V, VIH and VIL thresholds fall outside specification, and output drive strength degrades significantly - risking logic misreads and bus contention.

Does the 74V2G07STR require external pull-up resistors on its outputs?

Yes. All three outputs (1Y, 2Y, 3Y) are open-drain and must be pulled up externally to a valid logic HIGH voltage (e.g., 3.3V or 5V). Pull-up value depends on bus capacitance and speed requirements; 2.2 kΩ is typical for I²C at 100 kHz.

Is the 74V2G07STR pin-compatible with the 74LVC2G07?

No. While both are triple open-drain buffers in 8-pin packages, the 74V2G07STR uses SOT23-8L with pinout 1A–1Y–2A–GND–2Y–3A–3Y–VCC, whereas 74LVC2G07 uses SOT-363 with different pin assignment and spacing - requiring PCB redesign.

What is the maximum sink current per output at 125°C?

Per AC Electrical Characteristics table, IO = 8 mA is specified only at VCC = 4.5 V and TA = –55°C to +125°C. At 125°C, VOL remains ≤ 0.55 V under this load, confirming sustained 8 mA sink capability across full temperature range.
