Texas Instruments SN74LVC07APWE4

Overview

SN74LVC07APWE4 from Texas Instruments is a hex buffer and driver IC with six independent 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, accepts 5.5-V-tolerant inputs, and achieves 2.6 ns 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 SN74LVC07APWE4 datasheet, SN74LVC07APWE4 pinout, SN74LVC07APWE4 application, or SN74LVC07APWE4 equivalent, key selection criteria include open-drain drive strength (24 mA), Ioff support for live insertion, 5.5-V input tolerance, and TSSOP-14 package compatibility with high-density PCB layouts.

Technical Context

The SN74LVC07APWE4 implements six identical CMOS buffer stages, each with an open-drain output stage capable of sinking up to 24 mA at VCC = 3 V and 5.5 V on inputs/outputs regardless of VCC level. Its Ioff circuitry actively disables outputs when VCC = 0 V, preventing back-drive current during partial power-down.

This device operates across –40°C to +125°C and supports voltage translation between 1.8-V, 2.5-V, 3.3-V, and 5-V logic families. Propagation delay remains ≤3.1 ns over full temperature range at 5 V, with input thresholds defined per VCC band (e.g., VIH = 0.7 × VCC for 4.5–5.5 V).

FAQ

What is the maximum sink current per output of the SN74LVC07APWE4?

The SN74LVC07APWE4 supports up to 24 mA sink current per output at VCC = 3 V and ambient temperature. This rating is confirmed in the Switching Characteristics table of the official datasheet (SCAS595W, Section 6.6), and applies across the full operating temperature range of –40°C to +125°C. Exceeding this limit risks exceeding absolute maximum ratings and may degrade reliability.

Does the SN74LVC07APWE4 support level translation between different supply voltages?

Yes, the SN74LVC07APWE4 supports bidirectional level translation: its inputs accept voltages up to 5.5 V regardless of VCC (1.65–5.5 V), and its open-drain outputs can be pulled up to any voltage ≤5.5 V. This allows it to translate signals from a 5-V microcontroller to a 1.8-V FPGA input, or from a 3.3-V processor to a 5-V display interface - all using a single SN74LVC07APWE4 device.

Can the SN74LVC07APWE4 be used with VCC = 0 V in a live-insertion scenario?

Yes, the SN74LVC07APWE4 features Ioff circuitry that disables all outputs when VCC = 0 V, preventing back-drive current from live signal lines into the unpowered IC. This is explicitly documented in Section 8.1 and Feature bullet #5 of the datasheet, and makes the SN74LVC07APWE4 suitable for hot-plug applications such as modular SSD carriers or field-replaceable I/O cards where subsystems power up independently.

What is the propagation delay of the SN74LVC07APWE4 at 3.3 V operation?

At VCC = 3.3 V and TA = –40°C to +85°C, the SN74LVC07APWE4 has a maximum propagation delay (tpd) of 3.6 ns, as specified in Table 6-6 (Switching Characteristics) of the SCAS595W datasheet. At the extended temperature range (–40°C to +125°C), tpd increases to 4.1 ns - a critical value for timing-critical enable/control paths in industrial SSDs or real-time I/O systems.

Is the SN74LVC07APWE4 RoHS compliant and what is its moisture sensitivity level?

Yes, the SN74LVC07APWE4 is RoHS compliant (lead-free, halogen-free) and carries an MSL rating of Level-1 at 260°C peak reflow, meaning it has unlimited floor life and does not require dry-packaging or baking prior to soldering. This information is verified in TI's Packaging Information addendum (October 2025), confirming full compliance with J-STD-020 and EU RoHS Directive 2011/65/EU for the SN74LVC07APWE4 part number.
