Product details

Overview

SN74LV07ADRG4 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 logic, supports mixed-mode voltage translation (e.g., 3.3-V input to 5-V bus), delivers up to 16 mA sink current at 5 V, and features I_off protection for partial power-down. It is used in wired-OR bus interfaces and level-shifting applications in telecom infrastructure.

For engineers reviewing the SN74LV07ADRG4 datasheet, SN74LV07ADRG4 pinout, SN74LV07ADRG4 application, or SN74LV07ADRG4 equivalent, key selection criteria include open-drain output drive capability, 5.5-V input/output tolerance, I_off functionality for hot-swap safety, and SOIC-14 package compatibility with legacy board layouts.

Technical Context

The SN74LV07ADRG4 implements six independent non-inverting buffers, each with an open-drain output stage enabling wired-OR logic and flexible pull-up voltage selection. Its inputs tolerate up to 5.5 V regardless of V_CC, allowing direct interfacing with higher-voltage logic families while operating from as low as 2 V.

It incorporates I_off circuitry that disables all outputs when V_CC = 0 V, preventing back-current flow during power sequencing. The device meets JESD 78 Class II latch-up performance (>100 mA) and exceeds JESD 22 ESD ratings (2000-V HBM, 1000-V CDM).

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 systems
I_OL (max)	16 mA at V_CC = 5 V - defines maximum sink current per output for pull-up resistor sizing
Input Tolerance	0 V to 5.5 V - allows safe interfacing with higher-voltage logic without level shifters
I_off	5 µA max - ensures negligible leakage when powered down, critical for hot-swap and power-gated systems
t_PLH/t_PHL	3.4 ns to 7.1 ns at V_CC = 3.3 V, CL = 15 pF - determines maximum data rate in buffered control lines
V_OL (max)	0.55 V at I_OL = 16 mA, V_CC = 4.5 V - sets low-state voltage margin for noise immunity in open-drain buses
ESD Rating	2000-V HBM - meets industrial-grade handling requirements without special ESD precautions

Pinout & Package

SN74LV07ADRG4 is packaged in a 14-pin SOIC (D) body measuring 8.65 mm × 3.91 mm, with 1.27-mm lead pitch and 1.75-mm maximum height. This RoHS-compliant, NIPDAU-finished package supports standard reflow profiles (MSL Level-1).

Key Features

Feature	Design Value

FAQ

What is the maximum sink current per output of the SN74LV07ADRG4?

The SN74LV07ADRG4 supports a maximum sink current of 16 mA per output when V_CC = 5 V, as specified in the Electrical Characteristics table. At lower supply voltages, the rated I_OL decreases: 8 mA at 3.3 V and 2 mA at 2.3 V. These values define the upper limit for external pull-up resistor selection to ensure VOL remains within specification.

Does the SN74LV07ADRG4 support level translation between different voltage domains?

Yes, the SN74LV07ADRG4 supports bidirectional level translation due to its 5.5-V-tolerant inputs and open-drain outputs. For example, a 2.5-V microcontroller can drive SN74LV07ADRG4 inputs while its outputs pull down a 5-V bus line via an external pull-up - enabling seamless interfacing without additional translators.

What does the I_off feature do in the SN74LV07ADRG4?

The I_off feature in the SN74LV07ADRG4 disables all outputs when V_CC = 0 V, limiting off-state leakage current to ≤5 µA. This prevents damaging back-current flow from live system buses into a powered-down SN74LV07ADRG4, making it suitable for hot-swap and partial power-down architectures.

Can unused inputs on the SN74LV07ADRG4 be left floating?

No, unused inputs on the SN74LV07ADRG4 must be tied to either V_CC or GND to prevent undefined logic states and increased power consumption. TI explicitly recommends this in the datasheet (Section 7.3 Note) to avoid oscillation or excessive current draw caused by floating CMOS inputs.

What package type is used for the SN74LV07ADRG4?

The SN74LV07ADRG4 uses a 14-pin SOIC (D) package with dimensions 8.65 mm × 3.91 mm and 1.27-mm lead pitch. It is RoHS-compliant, features NIPDAU lead finish, and carries an MSL Level-1 rating for unlimited floor life under standard handling conditions.
