Product details

Overview

SN74LV07ADG4 from Texas Instruments is a hex buffer/driver IC with open-drain outputs, designed for 2-V to 5.5-V V_CC operation. It performs Y = A logic in positive polarity, supports mixed-mode voltage translation (e.g., 3.3-V input to 5-V bus), sinks up to 16 mA per output at 5 V, and features I_off for partial power-down isolation. It is used in wired-OR bus interfaces and level-shifting applications in telecom infrastructure.

For engineers reviewing the SN74LV07ADG4 datasheet, SN74LV07ADG4 pinout, SN74LV07ADG4 application, or SN74LV07ADG4 equivalent, key selection criteria include open-drain drive capability, 5.5-V tolerant inputs/outputs, I_off protection during power sequencing, and SOIC-14 package compatibility with industrial temperature range (–40°C to 125°C).

Technical Context

The SN74LV07ADG4 implements six independent non-inverting buffers, each with an open-drain output stage enabling wired-OR logic and flexible pull-up voltage selection. Its I_off circuitry actively disables outputs when V_CC = 0 V, preventing back-current flow and supporting hot-insertion scenarios.

Input thresholds scale with V_CC (VIH = 0.7×V_CC, VIL = 0.3×V_CC), ensuring reliable switching across 2.3 V–5.5 V supply voltages. Propagation delay ranges from 3.4 ns to 10.4 ns (CL = 15 pF, V_CC = 5 V to 2.5 V), with ground bounce (V_OLP) < 0.8 V and undershoot (V_OHV) > 2.3 V at 3.3 V.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2 V to 5.5 V - Enables direct interface with 2.5-V, 3.3-V, and 5-V logic domains without external level shifters.
I_OL (max)	16 mA at V_CC = 5 V - Sufficient to drive standard 5-V TTL loads or pull down 4.7-kΩ pull-ups on 5-V buses.
I_off	5 µA max - Ensures negligible leakage when powered down, critical for system-level power sequencing and battery-backed circuits.
t_PHL/t_PLH	3.4–10.4 ns (CL = 15 pF) - Supports high-speed digital control signaling up to ~50 MHz in low-capacitance environments.
Input Tolerance	0 V to 5.5 V - Allows safe connection to higher-voltage sources (e.g., 5-V microcontroller GPIO) while operating at 3.3 V or lower.
Operating Temp	–40°C to +125°C - Qualified for industrial and extended-temperature embedded systems including telecom base stations.

Pinout & Package

SN74LV07ADG4 is supplied in a 14-pin SOIC (D) package measuring 8.65 mm × 3.91 mm, with 1.27-mm lead pitch and 1.75-mm maximum height. The package is RoHS-compliant, lead-finished with NiPdAu, and rated MSL-1 (unlimited floor life).

Pin/Terminal	Circuit Role	Design Meaning
1A, 2A, 3A, 4A, 5A, 6A	Input	CMOS-compatible logic inputs accepting 0–5.5 V; no internal pull-up/down; must be tied to V_CC or GND if unused.
1Y, 2Y, 3Y, 4Y, 5Y, 6Y	Open-Drain Output	Active-low drivers requiring external pull-up; capable of sinking 16 mA at 5 V; tolerate 5.5-V pull-up voltage.
V_CC (Pin 14)	Power Supply	Primary supply rail (2–5.5 V); bypass capacitor required near pin for noise suppression.
GND (Pin 7)	Ground Reference	Common return path for all inputs, outputs, and internal circuitry; must be low-impedance.

Key Features

Feature	Design Value
Wide V_CC Range	2 V to 5.5 V operation enables single part to serve multiple voltage domains in mixed-signal systems.
5.5-V Input/Output Tolerance	Allows interfacing with legacy 5-V peripherals while powered from modern 3.3-V or 2.5-V rails - eliminates discrete level shifters.
I_off Protection	Prevents damaging current backflow during power-up/down or hot-swap events by disabling outputs when V_CC = 0 V.
Open-Drain Architecture	Enables wired-OR bus structures (e.g., I²C-like arbitration), active-high wired-AND logic, and flexible pull-up voltage selection (e.g., 3.3 V logic driving 5 V bus).
Latch-Up Immunity	Exceeds 100 mA per JESD 78 Class II - ensures robustness against transient overvoltage and ESD-induced latch-up in noisy industrial environments.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC07A	Lower V_CC min (1.65 V), higher I_OL (24 mA at 3.3 V), but only 3.6-V input tolerance.	Suitable for 1.8-V/3.3-V-only systems; not recommended for 5-V mixed-voltage buses.	Choose SN74LVC07A only if full 5.5-V tolerance is unnecessary and higher sink current at low V_CC is prioritized.
MC74LCX07DT	Same 2–5.5-V range and 5.5-V tolerance, but specified for –55°C to +125°C and uses different process (lower C_i = 1.2 pF).	Better suited for aerospace/military applications requiring extended temperature qualification and lower input capacitance.	Select MC74LCX07DT when extended temp range or reduced capacitive loading on driving source is required.

Compared with SN74LVC07A and MC74LCX07DT, SN74LV07ADG4 uniquely balances 5.5-V tolerance, industrial temperature range, and proven reliability in telecom and industrial control - making it optimal for mixed-voltage bus interfacing where 5-V compatibility and I_off are mandatory.

FAQ

What is the maximum sink current per output of the SN74LV07ADG4?

The SN74LV07ADG4 supports a maximum low-level output current (I_OL) of 16 mA when V_CC = 5 V, as specified in the Electrical Characteristics table. At lower supply voltages, the sink capability decreases - e.g., 8 mA at 3 V and 2 mA at 2.3 V. This rating assumes steady-state DC conditions and must not exceed the total device limit of ±50 mA through V_CC/GND.

Does the SN74LV07ADG4 support partial power-down operation?

Yes, the SN74LV07ADG4 includes I_off circuitry that disables all outputs when V_CC = 0 V, limiting I_off to 5 µA maximum. This feature prevents current backflow from live inputs or outputs into the unpowered device, making SN74LV07ADG4 suitable for hot-swap and power-gated subsystems in servers and telecom gear.

Can the SN74LV07ADG4 be used for level translation between 3.3-V and 5-V logic?

Yes, the SN74LV07ADG4 is explicitly designed for mixed-mode voltage operation: its inputs tolerate 0–5.5 V regardless of V_CC, and its open-drain outputs can be pulled up to any voltage ≤5.5 V. When powered at 3.3 V, SN74LV07ADG4 safely drives a 5-V bus using an external 5-V pull-up resistor - no additional components needed.

What is the operating temperature range for the SN74LV07ADG4?

The SN74LV07ADG4 is rated for an operating free-air temperature range of –40°C to +125°C, as confirmed in the Recommended Operating Conditions table. This industrial-grade specification makes SN74LV07ADG4 appropriate for deployment in harsh environments such as base station cabinets, factory-floor controllers, and automotive under-hood modules.

Is the SN74LV07ADG4 pin-compatible with other members of the SN74LVxxA family?

SN74LV07ADG4 shares the same 14-pin SOIC (D) footprint and pinout as other hex buffers in the LV family (e.g., SN74LV06A, SN74LV125A), but functional compatibility depends on logic type and output structure. SN74LV07ADG4 has open-drain outputs and non-inverting logic; substituting it for a push-pull or inverting variant would require schematic and firmware review.
