Product details

Overview

SN74LV07APWRG3 from Texas Instruments is a hex buffer/driver IC with open-drain outputs, designed for 2-V to 5.5-V V_CC operation in mixed-voltage systems. It provides six independent non-inverting buffers, supports 5.5-V-tolerant inputs and outputs, delivers up to 16 mA sink current at 5 V, and features I_off protection for partial power-down safety. It is commonly used in wired-OR logic, level translation, and LED driving in telecom infrastructure.

For engineers reviewing the SN74LV07APWRG3 datasheet, SN74LV07APWRG3 pinout, SN74LV07APWRG3 application, or SN74LV07APWRG3 equivalent, key selection considerations include its open-drain output architecture, 2–5.5 V supply range, 5.5-V input/output tolerance, I_off functionality for hot-swap compatibility, and TSSOP-14 package thermal performance (R_θJA = 128.7 °C/W).

Technical Context

The SN74LV07APWRG3 implements positive-logic Y = A Boolean function across six independent channels, with all outputs configured as open-drain MOSFETs. Its I_off circuitry actively disables outputs when V_CC = 0 V, preventing back-current flow during power sequencing.

It supports mixed-mode voltage translation: inputs accept 0–5.5 V regardless of V_CC, and outputs can be pulled up to any voltage ≤5.5 V. Propagation delays range from 3.4 ns (t_PHL, V_CC = 5 V, C_L = 15 pF) to 10.6 ns (t_PHL, V_CC = 3.3 V, C_L = 50 pF), with guaranteed operation from –40°C to +125°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2 V to 5.5 V - Enables direct use in 2.5 V, 3.3 V, and 5 V systems without level shifters.
Output Type	Open-drain - Allows wired-OR/AND logic, flexible pull-up voltage selection, and bidirectional bus interfacing.
I_OL Max	16 mA at V_CC = 5 V - Sufficient to drive LEDs, small relays, or standard CMOS loads with external pull-up.
Input Tolerance	0 V to 5.5 V - Permits connection to higher-voltage controllers (e.g., 5 V MCU GPIO) while powered from 3.3 V.
I_off	5 µA max - Ensures safe isolation during power-up/down sequences; prevents backfeeding into unpowered rails.
t_PLH/t_PHL	3.8–10.6 ns - Supports high-speed digital control signals up to ~100 MHz in light-load configurations.
Operating Temp	–40°C to +125°C - Qualified for industrial and extended-temperature embedded applications.

Pinout & Package

TSSOP-14 package (5.00 mm × 4.40 mm body, 0.65 mm pitch), lead finish: Sn (matte tin), MSL Level-1, RoHS compliant.

Pin/Terminal	Circuit Role	Design Meaning
1A, 2A, 3A, 4A, 5A, 6A	Input	CMOS-compatible digital inputs; 5.5-V tolerant, no clamping required when V_CC < 5.5 V.
1Y, 2Y, 3Y, 4Y, 5Y, 6Y	Open-drain output	Drains current only; requires external pull-up to define high state; supports mixed-voltage bus termination.
GND (Pin 7)	Ground reference	Common return path for all internal logic and output current; must be low-impedance for noise immunity.
V_CC (Pin 14)	Power supply	Supplies core logic; bypass capacitor (0.1 µF) required adjacent to pin for stable switching performance.

Key Features

Feature	Design Value
Wide V_CC range (2–5.5 V)	Eliminates need for separate voltage translators in multi-rail systems; simplifies BOM and layout.
5.5-V input/output tolerance	Enables direct interface with legacy 5 V logic or microcontrollers without external protection components.
I_off partial-power-down protection	Prevents destructive current flow when V_CC is off but inputs/outputs remain active - critical for hot-plug designs.
Low dynamic ground bounce (V_OLP < 0.8 V)	Reduces noise coupling into shared ground planes, improving signal integrity in dense PCB layouts.
Latch-up immunity >100 mA	Ensures robust operation under transient overvoltage or ESD events per JESD78 Class II.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC07APWR	Lower V_CC min (1.65 V), higher I_OL (24 mA at 3.3 V), no I_off support.	Not suitable for partial-power-down systems; better for high-speed 3.3 V-only designs with heavier loads.	Choose SN74LVC07APWR only if operating exclusively at ≥1.65 V and I_off is not required.
74AHC1G07DBVR	Single-channel, smaller SOT-23-5 package, 2–5.5 V range, no I_off, lower drive (8 mA).	Requires six units for full hex functionality; lacks integrated multi-channel coordination and thermal efficiency of TSSOP-14.	Use 74AHC1G07DBVR only for space-constrained single-signal buffering where channel count is minimal.

Compared with SN74LVC07APWR and 74AHC1G07DBVR, the SN74LV07APWRG3 uniquely combines I_off protection, 5.5-V tolerance, and six-channel integration in a thermally optimized TSSOP-14 package - making it the preferred choice for industrial and telecom systems requiring robust power sequencing and mixed-voltage interoperability.

FAQ

What is the maximum sink current capability of the SN74LV07APWRG3 at 3.3 V V_CC?

The SN74LV07APWRG3 delivers up to 8 mA sink current (I_OL) at V_CC = 3.3 V, as specified in the Electrical Characteristics table (7.5) of the SCES337K datasheet. This value is guaranteed across the full operating temperature range (–40°C to +125°C) and supports reliable driving of LEDs, optocouplers, and light logic loads with appropriate external pull-up resistors.

Does the SN74LV07APWRG3 support hot-swap or partial power-down operation?

Yes, the SN74LV07APWRG3 includes I_off circuitry that disables all outputs when V_CC = 0 V, limiting I_off to 5 µA maximum. This feature prevents damaging current backflow from live inputs or outputs into the unpowered device, making SN74LV07APWRG3 suitable for hot-plug applications such as modular telecom line cards and server baseboard management.

Can the SN74LV07APWRG3 inputs be driven by a 5 V microcontroller while V_CC is at 3.3 V?

Yes - the SN74LV07APWRG3 inputs are 5.5-V tolerant, meaning they safely accept 0–5.5 V signals regardless of V_CC level. When V_CC = 3.3 V, a 5 V MCU GPIO can directly drive any input (e.g., 1A–6A) without external resistors or clamping diodes, enabling seamless level translation in mixed-voltage systems.

What is the thermal resistance (R_θJA) of the SN74LV07APWRG3 in its TSSOP-14 package?

The SN74LV07APWRG3 in the PW (TSSOP-14) package has a junction-to-ambient thermal resistance (R_θJA) of 128.7 °C/W, as documented in Section 7.4 (Thermal Information) of the SCES337K datasheet. This value assumes standard JEDEC 2S2P test board conditions and informs thermal design margins for continuous operation at elevated ambient temperatures.

Is the SN74LV07APWRG3 pin-compatible with other members of the SN74LV07A family?

Yes - all SN74LV07A variants (e.g., SN74LV07ADR, SN74LV07ADBR, SN74LV07APWR) share identical pin configuration, function mapping, and electrical behavior. The SN74LV07APWRG3 uses the same TSSOP-14 footprint and pinout as SN74LV07APWR and SN74LV07APWRG4, differing only in lead finish (Sn vs. NiPdAu) and packaging compliance (RoHS, MSL).
