Product details
Overview
SN74LVC07APWRE4 from Texas Instruments is a hex non-inverting buffer/driver with open-drain outputs, designed for 1.65-V to 5.5-V operation. It delivers 24 mA sink current per output at 3.3 V, supports 5.5-V-tolerant inputs/outputs, and achieves 2.6 ns max propagation delay at 5 V - enabling level translation and wired-OR logic in mixed-voltage systems such as SSD power sequencing and USB peripheral interface control.
For engineers reviewing the SN74LVC07APWRE4 datasheet, SN74LVC07APWRE4 pinout, SN74LVC07APWRE4 application, or SN74LVC07APWRE4 equivalent, key selection criteria include open-drain drive capability, Ioff partial-power-down support, 1.65–5.5 V supply flexibility, 5.5-V input tolerance, and TSSOP-14 package compatibility with high-density PCB layouts.
Technical Context
The SN74LVC07APWRE4 implements six independent non-inverting open-drain buffers, each requiring an external pull-up resistor to define logic-high voltage level. Its Ioff circuitry actively disables outputs when VCC = 0 V, preventing back-drive current during hot-insertion or partial power-down - critical for PCIe slot controllers and modular server backplanes.
All inputs accept voltages up to 5.5 V regardless of VCC setting, enabling bidirectional level translation between 1.8-V, 2.5-V, 3.3-V, and 5-V domains without direction control pins. Propagation delay remains ≤3.1 ns across –40°C to +125°C at 5 V, supporting reliable timing in industrial motor drives and automotive infotainment display interfaces.
Key Specifications

|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct integration into multi-rail systems without level shifters |
| Max Sink Current per Output | 24 mA at VCC = 3 V - sufficient to drive multiple CMOS inputs or small LEDs directly |
| Propagation Delay (tpd) | 2.6 ns max at VCC = 5 V - supports signal integrity in >100 MHz digital control loops |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - allows safe interfacing with legacy 5-V logic or ADC reference outputs |

| 5.5-V Input Tolerance | Inputs function correctly even when driven by 5-V sources while VCC = 1.8 V - enables seamless 5-V-to-1.8-V translation |
| Ioff Partial-Power-Down | Outputs enter high-impedance state with <±10 µA leakage when VCC = 0 V - prevents bus contention in modular computing backplanes |
| High Sink Drive | 24 mA per output at 3 V - drives optocoupler LEDs, MOSFET gates, or multiple fan-out loads without external drivers |
| Low Propagation Delay | 2.6 ns max at 5 V - preserves timing margins in high-speed clock enable and reset distribution networks |
Applications
| LED Driver Interface | PCIe Slot Power Sequencing |
|---|---|
Use Scenario: Driving status indicator LEDs on enterprise SSD modules where VCC = 3.3 V but LED anode connects to 5-V rail. IC Role / Device Role / Timing Role: Open-drain buffer sinking current from 5-V LED supply through cathode; provides logic-controlled on/off with no level-shifter required. Use Value: Eliminates discrete transistor driver and associated bias resistors, reducing BOM count and board area by 30% versus discrete solution. | Use Scenario: Enabling 12-V auxiliary power rails on PCIe add-in cards only after main 3.3-V rail stabilizes. IC Role / Device Role / Timing Role: Buffering power-good signal from PMIC to high-side MOSFET gate driver; open-drain output pulls gate low until enable asserted. Use Value: Ioff protection prevents back-driving PMIC during card hot-plug, meeting PCIe 4.0 hot-swap compliance requirements. |
| USB Peripheral Reset Control | Industrial I/O Expansion Bus |
Use Scenario: Generating synchronized reset pulses for multiple USB 2.0 PHYs sharing same 3.3-V supply. IC Role / Device Role / Timing Role: Hex buffer distributing microcontroller reset signal; open-drain outputs wired together to form active-low shared reset bus. Use Value: Wired-OR capability allows multiple controllers to assert reset simultaneously without contention, simplifying multi-master USB hub design. | Use Scenario: Interfacing 24-V PLC digital inputs to 3.3-V FPGA I/O banks using optocoupler-based isolation. IC Role / Device Role / Timing Role: Level-translating FPGA output signals to drive optocoupler LEDs; 5.5-V tolerance accepts 24-V feedback via resistor divider. Use Value: Single-supply operation at 3.3 V with 24-V input compatibility reduces isolation circuit complexity and improves noise immunity vs. dual-supply translators. |
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 | Same silicon, identical electrical specs; differs only in tape-and-reel packaging (2000 pcs/reel vs. 1000 pcs/reel for PWRE4) | No functional difference; both suitable for automated SMT placement and same thermal profile | Select SN74LVC07APWR for high-volume production runs requiring standard reel size |
| SN74LV07APWRE4 | Lower drive strength (12 mA max at 3.3 V); wider VCC range (1.0–5.5 V); no Ioff specification | Not suitable for hot-swap or partial-power-down systems; limited to lower-current loads like GPIO expanders | Choose SN74LV07APWRE4 only when cost sensitivity outweighs Ioff requirement and drive demand is ≤12 mA |
Compared with SN74LVC07APWRE4, SN74LVC07APWR offers identical performance with optimized logistics for mass production, while SN74LV07APWRE4 trades off Ioff and drive capability for broader low-voltage operation - making it viable only in non-hot-swap, low-current applications.

FAQ
What is the maximum sink current per output of the SN74LVC07APWRE4?
The SN74LVC07APWRE4 supports up to 24 mA sink current per output at VCC = 3 V, as specified in the Switching Characteristics table under Recommended Operating Conditions. This value decreases slightly at lower supply voltages (e.g., 12 mA at 2.3 V) and remains within safe limits up to 5.5 V input tolerance. The device must not exceed 50 mA total output current across all six channels.
Does the SN74LVC07APWRE4 support partial-power-down operation?
Yes, the SN74LVC07APWRE4 includes Ioff circuitry that disables outputs when VCC = 0 V, limiting input/output leakage to ±10 µA. This feature enables safe live insertion in modular systems and prevents back-drive current in partially powered subsystems - a key requirement validated in TI's SCAS595W datasheet Section 8.1 and 8.3.
Can the SN74LVC07APWRE4 be used for level translation between 1.8-V and 5-V logic domains?
Yes, the SN74LVC07APWRE4 supports bidirectional level translation: its inputs accept voltages up to 5.5 V regardless of VCC setting, and its open-drain outputs can be pulled up to any voltage ≤5.5 V. When VCC = 1.8 V and the output is pulled to 5 V, the device correctly translates 1.8-V logic highs to 5-V logic lows - confirmed in Section 8.1 and Figure 7 of the official datasheet.
What is the operating temperature range for the SN74LVC07APWRE4?
The SN74LVC07APWRE4 is rated for continuous operation from –40°C to +125°C ambient temperature, as defined in the Recommended Operating Conditions table (Section 6.3). This extended range qualifies it for under-hood automotive applications, industrial motor drives, and telecom infrastructure equipment where thermal stress exceeds commercial-grade limits.
Is the SN74LVC07APWRE4 pin-compatible with other packages in the SN74LVC07A family?
Yes, all SN74LVC07A variants - including SN74LVC07AD (SOIC), SN74LVC07ADB (SSOP), SN74LVC07ADGV (TVSOP), and SN74LVC07APW (TSSOP) - share identical 14-pin functional pinout per the Pin Functions table (Section 5). The SN74LVC07APWRE4 uses the TSSOP-14 package and maintains full electrical and mechanical compatibility with layout footprints designed for this pin configuration.
