Product details
Overview
SN74LVC07APWG4 from Texas Instruments is a hex buffer/driver IC with six independent open-drain outputs, designed for level translation and wired-OR logic in 1.65 V to 5.5 V systems. It delivers 24 mA sink current per output at 3.3 V, supports 5.5-V-tolerant inputs/outputs, and features Ioff for live insertion and partial-power-down protection. It is used in SSD power sequencing, HDMI CEC signal conditioning, and I²C bus voltage translation.
For engineers reviewing the SN74LVC07APWG4 datasheet, SN74LVC07APWG4 pinout, SN74LVC07APWG4 application, or SN74LVC07APWG4 equivalent, key selection criteria include open-drain drive strength, 5.5-V input tolerance, Ioff-enabled back-drive immunity, and TSSOP-14 package compatibility with high-density PCB layouts.
Technical Context
The SN74LVC07APWG4 implements six identical CMOS buffer stages, each with an open-drain NMOS output stage and no internal pull-up. Its input structure accepts voltages up to 5.5 V regardless of VCC (1.65–5.5 V), enabling bidirectional level shifting between disparate supply domains. The Ioff circuit actively disables all outputs when VCC = 0 V, blocking current flow from powered inputs or outputs into the unpowered device.
Propagation delay is specified down to 2.6 ns at 5 V and remains ≤3.1 ns across –40°C to +125°C, supporting reliable operation in high-speed digital interfaces. Latch-up immunity exceeds 250 mA per JESD17, and ESD robustness includes ±4000 V HBM and ±1500 V CDM ratings - critical for manufacturing and field reliability in consumer and industrial systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables single-supply operation across 1.8-V, 2.5-V, 3.3-V, and 5-V logic families. |
| Output Sink Current | 24 mA per channel at VCC = 3 V - sufficient to drive multiple TTL loads or LED indicators directly. |
| Input/Output Voltage Tolerance | Up to 5.5 V - allows interfacing with 5-V microcontrollers while powered from 3.3-V rails without external level shifters. |
| Max Propagation Delay | 2.6 ns at VCC = 5 V, TA = –40°C to +85°C - supports clean signal integrity in sub-100-MHz digital control paths. |
| Ioff Current | ±10 µA at VCC = 0 V - prevents damaging back-current during hot-plug or mixed-rail power sequencing. |
| Operating Temperature | –40°C to +125°C - qualified for automotive under-hood, industrial motor control, and telecom infrastructure use. |
| ESD Rating | ±4000 V HBM - meets JEDEC JS-001 for robust handling in automated assembly and end-equipment environments. |
Pinout & Package
TSSOP-14 package (5.00 mm × 4.40 mm body, 0.65 mm pitch), lead-free and RoHS-compliant, optimized for automated placement and thermal performance in space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 (1A–6A) | Input | CMOS-compatible logic inputs tolerant to 5.5 V - accept signals from any VCC domain without clamping diodes or external resistors. |
| 2, 4, 6, 8, 10, 12 (1Y–6Y) | Open-Drain Output | Active-low NMOS drain only - requires external pull-up for logic HIGH; enables wired-OR, I²C, SMBus, and interrupt bus sharing. |
| 7 | GND | Ground reference for all internal circuitry and I/O - must be low-impedance and co-located with bypass capacitors. |
| 14 | VCC | Primary power supply (1.65–5.5 V) - powers internal logic and defines output LOW threshold; decoupling capacitor required. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–5.5 V) | Eliminates need for separate level-shifting ICs when interfacing 1.8-V FPGAs with 5-V peripherals. |
| 5.5-V-tolerant I/O | Permits direct connection to legacy 5-V controllers without series resistors or voltage dividers - reduces BOM count and layout area. |
| Ioff partial-power-down support | Enables safe insertion into live backplanes or hot-swap modules where VCC may be sequenced independently from system IO rails. |
| 24-mA sink capability per output | Drives standard LEDs (20 mA), multiple 74LVC inputs (≤10 pF), or optocoupler LEDs without external drivers. |
| Low propagation delay (2.6 ns @ 5 V) | Maintains timing margins in high-speed enable/disable paths for DDR memory buffers, display backlight control, and sensor interface gating. |

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 |
|---|---|---|---|
| SN74LVC06APW | Inverting logic function (buffer outputs inverted); same VCC range, Ioff, and drive strength. | Requires logic inversion in signal path - unsuitable where non-inverting polarity is mandatory (e.g., active-HIGH enable lines). | Select SN74LVC06APW only when system-level logic accommodates inversion; otherwise, SN74LVC07APWG4 is required for true non-inverting buffering. |
| 74AHC07PW | Higher VCC max (5.5 V same), but no Ioff support and narrower temp range (–40°C to +125°C vs. AHC's –40°C to +85°C). | Not suitable for hot-swap or partial-power-down systems due to lack of Ioff; limited to fixed-rail, always-on applications. | Choose 74AHC07PW only in cost-sensitive, single-rail consumer designs where Ioff and extended temperature are not required. |
Compared with SN74LVC06APW and 74AHC07PW, SN74LVC07APWG4 uniquely combines non-inverting open-drain operation, full Ioff protection, and industrial temperature support - making it the only drop-in option for robust, mixed-voltage, hot-pluggable systems requiring polarity fidelity.

FAQ
What is the maximum sink current per output of the SN74LVC07APWG4?
The SN74LVC07APWG4 delivers up to 24 mA sink current per output at VCC = 3 V and TA = 25°C, with guaranteed minimums of 12 mA at 2.3 V and 4 mA at 1.65 V. This rating applies under recommended operating conditions and must not be exceeded continuously to maintain reliability and thermal stability in the TSSOP-14 package.
Does the SN74LVC07APWG4 support level translation between different voltage domains?
Yes, the SN74LVC07APWG4 supports bidirectional level translation: its inputs and open-drain outputs tolerate voltages up to 5.5 V regardless of VCC (1.65–5.5 V). This allows it to translate signals from a 5-V microcontroller to a 1.8-V FPGA input or vice versa - provided external pull-ups match the destination domain voltage.
Can the SN74LVC07APWG4 be used in hot-swap or partial-power-down applications?
Yes, the SN74LVC07APWG4 includes Ioff circuitry that disables all outputs when VCC = 0 V, limiting Ioff current to ±10 µA. This prevents damaging back-current flow from powered inputs or outputs into the unpowered device - a requirement for safe hot-plug operation in modular systems and server backplanes.
What is the propagation delay of the SN74LVC07APWG4 at 3.3 V?
At VCC = 3.3 V and TA = –40°C to +85°C, the SN74LVC07APWG4 has a maximum propagation delay (tpd) of 3.6 ns. Over the extended industrial range (–40°C to +125°C), the max tpd increases to 4.1 ns - verified per TI's SCAS595W datasheet Section 6.6.
Is the SN74LVC07APWG4 RoHS-compliant and lead-free?
Yes, the SN74LVC07APWG4 is RoHS-compliant and lead-free, with NIPDAU (nickel/palladium/gold) lead finish. It carries MSL Level-1 rating (unlimited floor life at ≤30°C/60% RH) and is qualified for reflow soldering up to 260°C peak temperature - fully compatible with modern lead-free assembly processes.
