Texas Instruments SN74LV07ADGVR

Overview

SN74LV07ADGVR 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 safety. It is used in telecom infrastructure bus interfacing and server-level level-shifting applications.

For engineers reviewing the SN74LV07ADGVR datasheet, SN74LV07ADGVR pinout, SN74LV07ADGVR application, or SN74LV07ADGVR equivalent, key selection criteria include open-drain output drive capability, 5.5-V tolerant inputs/outputs, I_off behavior during power sequencing, and TVSOP-14 package compatibility with high-density PCB layouts.

Technical Context

The SN74LV07ADGVR implements six independent non-inverting buffers, each with an open-drain output stage enabling wired-OR logic and flexible pull-up voltage selection. Its I_off circuitry actively disables outputs when V_CC = 0 V, preventing back-current flow and supporting hot-insertion scenarios.

Input thresholds scale with V_CC (VIH = 0.7×V_CC, VIL = 0.3×V_CC), ensuring robust noise immunity across 2–5.5 V supply range. Propagation delay is 3.8–7.5 ns (V_CC = 5 V, C_L = 15 pF), and dynamic output undershoot/overshoot is characterized at <0.8 V VOLP and >2.3 V VOHV (V_CC = 3.3 V).

FAQ

What is the function of SN74LV07ADGVR?

SN74LV07ADGVR is a hex non-inverting buffer with open-drain outputs. Each channel implements Y = A logic in positive logic, allowing it to drive external pull-up networks for level translation, wired-OR logic, or LED control. It operates from 2 V to 5.5 V and features I_off protection for safe power-down operation. The SN74LV07ADGVR is not a push-pull driver - its outputs require external pull-up resistors to achieve high logic states.

Does SN74LV07ADGVR support level translation between different voltage domains?

Yes, SN74LV07ADGVR supports bidirectional level translation: its inputs tolerate up to 5.5 V regardless of V_CC, and its open-drain outputs can be pulled up to any voltage ≤5.5 V. For example, with V_CC = 3.3 V, it accepts 5-V inputs and drives a 5-V bus via external pull-up - enabling seamless interface between 3.3-V microcontrollers and 5-V peripherals without additional components.

What is the purpose of the I_off feature in SN74LV07ADGVR?

The I_off feature in SN74LV07ADGVR disables output drivers when V_CC = 0 V, limiting I_off current to ≤5 µA. This prevents damaging back-current flow from live inputs or outputs into the unpowered IC - a critical requirement for hot-plug systems, modular backplanes, and partial-power-down architectures. The SN74LV07ADGVR maintains this protection across –40°C to +125°C.

What package type does SN74LV07ADGVR use, and what are its key mechanical dimensions?

SN74LV07ADGVR uses a 14-pin TVSOP (Thin Very Small Outline Package) with 0.5-mm lead pitch. Its nominal body dimensions are 3.60 mm × 4.40 mm, with maximum height of 1.20 mm. The package complies with JEDEC MO-153 and is optimized for automated assembly and high-density PCB layouts. Pin 1 is marked by a dimple in the top-left corner of the package.

Can SN74LV07ADGVR drive multiple loads simultaneously on a shared bus?

Yes, SN74LV07ADGVR's open-drain outputs support wired-OR and wired-AND configurations. Multiple outputs can be tied together with a single pull-up resistor to implement shared bus signaling - such as interrupt lines or fault-reporting busses. Total sink current must remain within 50 mA (device limit), and per-output current must not exceed 35 mA. Layout best practices (short traces, controlled impedance) are recommended to suppress ringing on fast edges.
