Texas Instruments SN74LV07ADR

Overview

SN74LV07ADR 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 for partial power-down protection-used in telecom infrastructure bus interfacing and LED driver control.

For engineers reviewing the SN74LV07ADR datasheet, SN74LV07ADR pinout, SN74LV07ADR application, or SN74LV07ADR equivalent, key selection criteria include open-drain output drive capability, 5.5-V tolerant inputs/outputs, I_off behavior during power sequencing, and SOIC-14 package compatibility with legacy 5-V and modern low-voltage logic systems.

Technical Context

The SN74LV07ADR implements six independent non-inverting buffers, each with an open-drain output stage enabling wired-OR and level-shifting functions. Its I_off circuitry actively disables outputs when V_CC = 0 V, preventing back-current flow and supporting hot-insertion scenarios.

All inputs tolerate voltages up to 5.5 V regardless of V_CC, and outputs are similarly 5.5-V tolerant-enabling bidirectional voltage translation between 2.5-V, 3.3-V, and 5-V domains without external components. Propagation delay ranges from 3.4 ns to 10.4 ns (V_CC = 5 V to 2.5 V, C_L = 15 pF).

FAQ

What is the maximum sink current per output of the SN74LV07ADR?

The SN74LV07ADR supports up to 16 mA sink current per output when V_CC = 5 V, as specified in the Electrical Characteristics table. This value decreases to 8 mA at 3 V and 2 mA at 2.3 V. The absolute maximum continuous output current is ±35 mA, but sustained operation above 16 mA risks exceeding thermal limits in SOIC-14 packaging.

Does the SN74LV07ADR support level shifting between different supply voltages?

Yes, the SN74LV07ADR supports bidirectional level shifting: its inputs tolerate 0–5.5 V regardless of V_CC, and its open-drain outputs are also 5.5-V tolerant. For example, with V_CC = 3.3 V, it can accept 5-V inputs and drive a 5-V pull-up bus-enabling translation from 5-V logic to 3.3-V domains without external components.

What is the purpose of the I_off feature in the SN74LV07ADR?

The I_off feature in the SN74LV07ADR disables output drivers when V_CC = 0 V, limiting I_off current to <5 µA. This prevents damaging back-current flow from live system buses into a powered-down section-critical for hot-swap architectures, partial power-down modes, and systems with staggered power sequencing.

Can unused inputs on the SN74LV07ADR be left floating?

No, unused inputs on the SN74LV07ADR must be tied to V_CC or GND. Floating CMOS inputs cause undefined logic states, increased power consumption, and potential oscillation due to noise coupling. TI's application report SCBA004 explicitly recommends biasing all unused inputs to ensure stable operation and prevent latch-up or EMI issues.

What package type is used for the SN74LV07ADR and what are its key mechanical dimensions?

The SN74LV07ADR uses the SOIC-14 (D) package: 8.65 mm × 3.91 mm body size, 1.75 mm maximum height, 1.27 mm lead pitch, and gull-wing leads. It complies with JEDEC MS-012 variation AB, has NiPdAu/Sn lead finish, and carries MSL Level-1 rating for unlimited floor life at ≤30°C/60% RH.
