Texas Instruments SN74LV07APWT

Overview

SN74LV07APWT 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 interfaces and LED driver control circuits.

For engineers reviewing the SN74LV07APWT datasheet, SN74LV07APWT pinout, SN74LV07APWT application, or SN74LV07APWT equivalent, key selection criteria include open-drain output compatibility, 5.5-V tolerant inputs/outputs, I_off behavior during power sequencing, and TSSOP-14 package thermal performance under industrial temperature range (–40°C to 125°C).

Technical Context

The SN74LV07APWT implements six independent non-inverting buffers with open-drain outputs, 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.

Each channel accepts 5.5-V-tolerant inputs across the full 2-V to 5.5-V supply range and sinks up to 16 mA per output at V_CC = 5 V. Propagation delay ranges from 3.4 ns to 7.5 ns (V_CC = 5 V, C_L = 15 pF), with ground bounce (V_OLP) < 0.8 V and undershoot (V_OHV) > 2.3 V at 3.3 V.

FAQ

What is the function of SN74LV07APWT?

The SN74LV07APWT is a hex non-inverting buffer with open-drain outputs, performing Y = A logic in positive logic. Each of its six channels accepts 5.5-V-tolerant inputs and sinks current to ground when enabled, requiring external pull-up resistors. It supports level translation, wired-OR logic, and I²C bus buffering. The SN74LV07APWT integrates I_off circuitry to disable outputs during power-down, preventing back-current flow.

Does SN74LV07APWT support mixed-voltage operation?

Yes, SN74LV07APWT supports true mixed-voltage operation: inputs tolerate up to 5.5 V regardless of V_CC (2 V to 5.5 V), and outputs can be pulled up to any voltage ≤5.5 V. This allows interfacing a 3.3-V microcontroller with a 5-V bus or sensor without external level shifters. The SN74LV07APWT maintains specified timing and drive strength across the full V_CC range.

What is the maximum sink current per output of SN74LV07APWT?

The SN74LV07APWT delivers up to 16 mA per output at V_CC = 5 V, 8 mA at V_CC = 3.3 V, and 2 mA at V_CC = 2.3 V, as specified in the Electrical Characteristics table. Total device output current must not exceed 50 mA. Exceeding these limits risks exceeding absolute maximum ratings and degrading long-term reliability. The SN74LV07APWT datasheet defines these values under recommended operating conditions with proper thermal management.

How does I_off work in SN74LV07APWT?

I_off in SN74LV07APWT is an integrated circuit feature that disables all outputs when V_CC = 0 V, blocking current flow from inputs or outputs into the powered-down device. This prevents damaging back-current during hot-swap or partial power-down sequences. Measured at ≤5 µA, I_off is guaranteed across –40°C to 125°C. The SN74LV07APWT activates I_off automatically - no external control is needed.

Is SN74LV07APWT RoHS compliant and what is its package type?

Yes, SN74LV07APWT is RoHS compliant with lead finish NiPdAu or Sn, packaged in a 14-pin TSSOP (PW) with 5.00 mm × 4.40 mm body size and 0.65 mm pitch. It carries MSL Level-1 rating (unlimited floor life at ≤30°C/60% RH) and is qualified for reflow at 260°C peak. The SN74LV07APWT marking is "LV07A", and its tape-and-reel packaging supports automated SMT assembly with 2000 units per reel.
