Product details

Overview

SN74LV07APWR 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 (non-inverting), supports mixed-mode voltage translation, features I_off protection during power-down, and delivers up to 16 mA sink current at 5 V - used in level-shifting interfaces and wired-OR bus systems.

For engineers reviewing the SN74LV07APWR datasheet, SN74LV07APWR pinout, SN74LV07APWR application, or SN74LV07APWR equivalent, this page provides verified package mapping (TSSOP-14), confirmed open-drain output behavior, I_off functionality, voltage-tolerant inputs/outputs (to 5.5 V), and real-world timing specs (e.g., t_PHL = 5 ns @ 3.3 V, CL = 15 pF).

Technical Context

The SN74LV07APWR implements six independent non-inverting buffers, each with an open-drain output stage enabling wired-OR logic and bidirectional level translation. Its I_off circuitry actively disables outputs when V_CC = 0 V, preventing back-current flow and supporting hot-insertion in partial-power-down systems.

All inputs tolerate voltages up to 5.5 V regardless of V_CC, and outputs are similarly 5.5-V tolerant with programmable pull-up - allowing interface between 2.5-V, 3.3-V, and 5-V domains without external translators. Propagation delay varies from 3.4 ns to 11.1 ns depending on V_CC and load capacitance.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2 V to 5.5 V - enables single-supply operation across 2.5-V, 3.3-V, and 5-V logic families.
Output Type	Open-drain - requires external pull-up; supports wired-OR, I²C-like buses, and level translation.
I_OL Max	16 mA @ V_CC = 5 V - defines maximum sink capability per output; limits pull-up resistor selection.
t_PHL/t_PLH	3.4 ns / 3.8 ns @ V_CC = 5 V, CL = 15 pF - determines minimum clock/data rate for high-speed buffering.
I_off	5 µA max @ V_CC = 0 V - ensures safe isolation during power sequencing or hot-swap events.
Input Voltage Tolerance	0 V to 5.5 V - allows direct connection to higher-voltage controllers without clamping diodes.
Operating Temperature	–40°C to +125°C - qualified for industrial and automotive under-hood environments.

GND (Pin 7)	Ground reference	Primary return path for all internal logic and output sink current.
V_CC (Pin 14)	Power supply	Supplies core logic; powers internal bias networks; must be bypassed with 0.1-µF capacitor.

Key Features

Feature	Design Value
Wide V_CC range (2 V–5.5 V)	Eliminates need for separate voltage rails when interfacing mixed-voltage subsystems.
I_off protection	Prevents damaging back-current during power-down or hot-plug; critical for system-level reliability.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC07APW	Lower V_CC min (1.65 V), higher I_OL (24 mA @ 3.3 V), no I_off spec	Better for low-voltage portable systems; unsuitable where power-down isolation is required	Select SN74LVC07APW only if operating below 2 V or needing >16 mA drive; verify I_off not needed.
MC74LCX07DT	Same V_CC range (2–5.5 V), lower C_i (1.2 pF), no I_off guarantee, different pinout	Preferred for ultra-low-capacitance routing; lacks TI's I_off validation for hot-swap use cases	Choose MC74LCX07DT for high-frequency signal integrity; avoid where power sequencing safety is critical.

FAQ

What is the maximum sink current per output of the SN74LV07APWR?

The SN74LV07APWR supports up to 16 mA sink current per output when V_CC = 5 V, as specified in the Electrical Characteristics table. At lower V_CC levels, the maximum sink current decreases - e.g., 8 mA at 3 V and 2 mA at 2.3 V. Exceeding these values risks exceeding absolute maximum ratings and may degrade reliability.

Does the SN74LV07APWR support level translation between 1.8-V and 5-V logic domains?

The SN74LV07APWR accepts input voltages up to 5.5 V regardless of V_CC, enabling translation from higher-voltage sources (e.g., 5-V) down to its V_CC-referenced logic. However, it cannot translate *up* from 1.8-V inputs unless V_CC ≥ 2 V and the 1.8-V signal meets VIH/VIL thresholds - which it does not at 1.8-V V_CC. So SN74LV07APWR is not suitable for 1.8-V-to-5-V translation.

Is the SN74LV07APWR pin-compatible with the SN74LV07ADR (SOIC-14)?

Yes - the SN74LV07APWR (TSSOP-14) and SN74LV07ADR (SOIC-14) share identical pin numbering, function mapping, and logic behavior. Both have 1A–6A inputs on pins 1/3/5/9/11/13 and corresponding 1Y–6Y outputs on pins 2/4/6/8/10/12, with GND on pin 7 and V_CC on pin 14. Only the physical package differs; no PCB redesign is needed for footprint substitution.

How does the I_off feature of the SN74LV07APWR improve system reliability?

The I_off feature in the SN74LV07APWR disables all outputs when V_CC = 0 V, limiting leakage current to ≤5 µA. This prevents back-driving of powered-down sections by live signals - a critical safeguard during hot-swap, partial power-down, or board removal. It eliminates risk of latch-up or damage to upstream devices, directly enhancing system-level fault tolerance.

Can the SN74LV07APWR drive standard LED loads directly?

Yes - the SN74LV07APWR can drive LEDs directly in sink configuration: connect LED anode to V_CC (or higher rail via external pull-up), cathode to an output pin (e.g., 1Y), and limit current with a series resistor. With 16 mA max sink capability at 5 V, it supports typical indicator LEDs (e.g., 2–10 mA). Ensure total device current stays ≤50 mA and individual output ≤35 mA per Absolute Maximum Ratings.
