Product details

Overview

74V2G70STR from STMicroelectronics is a triple non-inverting buffer IC in SOT23-8L package, operating from 2V to 5.5V, delivering 3.0ns typical propagation delay at 5V, ±8mA output drive at 4.5V, and 1µA max quiescent current - enabling low-power, high-speed level translation between 3V and 5V systems in portable electronics.

For engineers reviewing the 74V2G70STR datasheet, 74V2G70STR pinout, 74V2G70STR application, or 74V2G70STR equivalent, key selection criteria include its triple-buffer architecture with power-down protection, symmetrical I_O drive, wide V_CC range, ESD-hardened inputs/outputs, and compatibility with battery-powered 3V/5V mixed-voltage interfaces.

Technical Context

This device implements three independent CMOS buffer stages using sub-micron C2MOS technology, each featuring rail-to-rail input tolerance (−0.5V to +7.0V), power-down protection on all pins, and latch-up immunity per JEDEC JESD78. Inputs accept voltages beyond V_CC, enabling safe hot-plug and voltage-level bridging.

Its symmetrical output impedance (|I_OH| = I_OL ≥ 8mA at V_CC = 4.5V) ensures matched rise/fall times (t_PLH ≅ t_PHL), while balanced propagation delays and 28% V_CC noise margin support robust signal integrity in noisy portable environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.0V to 5.5V - supports dual-supply 3V/5V system interfacing without level shifters
t_PD (Typ.)	3.0ns at V_CC = 5.0V, CL = 15pF - enables >100MHz signal routing in compact portable designs
I_OH/I_OL	≥8mA at V_CC = 4.5V - drives multiple CMOS loads or short PCB traces without external buffering
I_CC (Max)	1µA at T_A = 25°C - minimizes standby current in battery-operated PDA/camcorder power domains
V_NIH/V_NIL	28% V_CC (min) - rejects >1.4V noise on 5V rails and >0.84V noise on 3V rails
Input Voltage Range	−0.5V to +7.0V - allows safe operation with inputs floating or driven above V_CC during power sequencing

Pinout & Package

SOT23-8L (8-pin small outline transistor package), 3.0mm × 3.0mm body, 0.65mm pitch, tape-and-reel packaging for automated assembly.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 6	1A, 2A, 3A	Independent logic inputs - each accepts −0.5V to +7.0V regardless of V_CC; protected against ESD and overvoltage
7, 5, 2	1Y, 2Y, 3Y	Non-inverting buffered outputs - deliver symmetrical ±8mA drive at 4.5V with matched t_PLH/t_PHL
4	GND	Reference ground terminal - shared return path for all three buffers; decoupling capacitor required near pin
8	V_CC	Positive supply - powers all three buffers; supports 2V–5.5V operation with internal regulation-free CMOS core

Key Features

Feature	Design Value
Triple non-inverting buffer	Three independent, electrically isolated channels in one SOT23-8L footprint - saves board space vs. discrete solutions
Power-down protection	All inputs and outputs remain high-impedance and fault-tolerant when V_CC = 0V - prevents back-driving and bus contention
Rail-to-rail input tolerance	Accepts −0.5V to +7.0V on any input pin - eliminates need for external clamping diodes in mixed-voltage interconnects
ESD-hardened I/O	Qualified to >2kV HBM - protects against handling damage and transient events in handheld device assembly and field use

Equivalent & Alternatives

The following parts are listed as comparable options for similar triple buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC3G07DCUR	3.3V-only V_CC range (1.65–5.5V), lower t_PD (2.5ns typ.), no −0.5V input tolerance	Not suitable for 2V operation or inputs driven below GND; requires tighter supply control	Prefer when system operates strictly at 3.3V and minimal propagation delay is critical
74AUP3G07GW,125	Lower I_OH/I_OL (4mA @ 3.3V), higher noise margin (40% V_CC), 0.8–3.6V V_CC range	Better for ultra-low-power sub-1V logic domains but lacks 5V drive capability	Choose for energy-constrained sub-10µA sleep systems where 5V interface is not required

Compared with SN74LVC3G07DCUR and 74AUP3G07GW,125, the 74V2G70STR uniquely supports 2V–5.5V operation with full −0.5V to +7.0V input tolerance and 8mA drive at 4.5V - making it the only option for robust 3V/5V bidirectional bridging in legacy portable equipment.

FAQ

Is the 74V2G70STR compatible with 2.0V logic systems?

Yes. The device is fully specified down to V_CC = 2.0V, with guaranteed VIH/VIL thresholds (1.5V/0.5V) and functional t_PD ≤ 9.0ns at −55°C to +125°C. Its 2V–5.5V operating range makes it suitable for early low-voltage microcontroller interfaces and energy-harvesting sensor nodes.

Can inputs be driven above V_CC without damage?

Yes. Absolute maximum ratings permit DC input voltages from −0.5V to +7.0V regardless of V_CC value. This enables safe hot-plug operation, mixed-voltage debugging, and direct connection to 5V peripherals even when powered from 3V - no external clamping diodes required.

What is the significance of power-down protection on inputs and outputs?

When V_CC = 0V, all inputs and outputs enter high-impedance state with leakage < 10µA, preventing back-powering of the supply rail or loading of upstream/downstream devices. This avoids bus contention and unintended activation in multi-rail systems during power sequencing or brown-out conditions.

Does the 74V2G70STR support 50pF load capacitance at full speed?

Yes. AC specifications confirm t_PD ≤ 6.5ns (typ.) at V_CC = 5.0V with CL = 50pF, and ≤ 8.0ns (max.) over −40°C to +85°C. The 12pF CPD value indicates low dynamic power consumption, supporting stable operation on long traces or multiple fan-outs without signal degradation.
