Texas Instruments SN74LVC07APW

Overview

SN74LVC07APW 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, 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 SN74LVC07APW datasheet, SN74LVC07APW pinout, SN74LVC07APW application, or SN74LVC07APW equivalent, key selection criteria include open-drain drive strength (24 mA), Ioff-enabled live insertion support, 1.65–5.5 V supply flexibility, 5.5-V input/output tolerance, and TSSOP-14 thermal performance (RθJA = 160.3°C/W).

Technical Context

The SN74LVC07APW implements six identical CMOS buffer stages, each with an open-drain output requiring external pull-up for logic high assertion. Its Ioff circuitry actively disables outputs when VCC = 0 V, preventing back-drive current during partial power-down - critical for hot-swap and system-level power sequencing.

All inputs accept voltages up to 5.5 V regardless of VCC setting, enabling bidirectional voltage translation (e.g., 1.8-V MCU GPIO driving 5-V bus lines). Propagation delay is characterized across –40°C to +125°C and VCC = 1.8 V to 5 V, with worst-case tpd = 3.1 ns at 5 V over full temperature range.

FAQ

What is the maximum sink current per output of the SN74LVC07APW?

The SN74LVC07APW supports up to 24 mA sink current per output at VCC = 3 V, as specified in the Electrical Characteristics table under IOL test conditions. This rating holds across the full operating temperature range (–40°C to +125°C) and enables direct driving of multiple CMOS loads or indicator LEDs without external amplification. The SN74LVC07APW maintains this drive strength while operating from 1.65 V to 5.5 V supplies.

Does the SN74LVC07APW support level translation between different voltage domains?

Yes, the SN74LVC07APW supports bidirectional level translation due to its 5.5-V tolerant inputs and open-drain outputs. Inputs accept voltages up to 5.5 V regardless of VCC setting (1.65–5.5 V), allowing a 1.8-V-powered SN74LVC07APW to safely receive 5-V signals. When paired with an external pull-up to a higher voltage rail, its outputs can assert logic high at that rail voltage - making the SN74LVC07APW ideal for interfacing mixed-voltage subsystems without dedicated translator ICs.

Can the SN74LVC07APW be used in hot-swap or partial-power-down applications?

Yes, the SN74LVC07APW includes Ioff circuitry that disables outputs when VCC = 0 V, limiting Ioff current to ±10 µA. This feature prevents damaging back-current flow from live I/O lines into a powered-down device - a critical requirement for hot-swap modules, modular power supplies, and systems with staggered power sequencing. The SN74LVC07APW maintains this protection across –40°C to +125°C, ensuring reliability in industrial and telecom infrastructure.

What is the propagation delay of the SN74LVC07APW at 3.3 V supply?

At VCC = 3.3 V and TA = –40°C to +85°C, the SN74LVC07APW has a maximum propagation delay (tpd) of 3.6 ns, as specified in the Switching Characteristics table. Under extended temperature (–40°C to +125°C), the worst-case tpd increases to 4.1 ns. These values reflect the time from input transition to valid output transition under CL = 30 pF load conditions - confirming suitability for high-speed digital interfaces up to 100 MHz with timing margin.

Is the SN74LVC07APW pin-compatible with other packages in the SN74LVC07A family?

No, the SN74LVC07APW (TSSOP-14) shares identical pin configuration and function mapping with other SN74LVC07A variants (e.g., SOIC, SSOP, TVSOP), as confirmed in the Pin Configuration and Functions section of the datasheet. All 14-pin packages use the same top-view layout: inputs on odd pins (1A–6A), outputs on even pins (1Y–6Y), GND on pin 7, and VCC on pin 14. However, mechanical dimensions and thermal characteristics differ - so board layout must match the specific package's footprint and soldering profile.
