Texas Instruments SN74LV07ANS

Overview

SN74LV07ANS 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 wired-OR bus interfaces on telecom infrastructure backplanes.

For engineers reviewing the SN74LV07ANS datasheet, SN74LV07ANS pinout, SN74LV07ANS application, or SN74LV07ANS equivalent, this page provides verified functional identity, validated SOIC-14 package mapping, confirmed open-drain output behavior, I_off and overvoltage-tolerant input specs, and two technically documented alternative parts for system-level buffer replacement.

Technical Context

The SN74LV07ANS implements six independent non-inverting buffers, each with an open-drain output stage enabling wired-OR logic and level translation. Its inputs tolerate voltages up to 5.5 V regardless of V_CC, and its I_off circuitry disables outputs when V_CC = 0 V, preventing back-current flow during power sequencing.

Propagation delay ranges from 3.4 ns (t_PHL, V_CC = 5 V, C_L = 15 pF) to 15.2 ns (t_PLH, V_CC = 3.3 V, C_L = 50 pF); output low voltage is ≤0.55 V at I_OL = 16 mA and V_CC = 4.5 V. The device operates across –40°C to 125°C and meets JESD 78 Class II latch-up performance (>100 mA).

Compared with SN74LV07ANS, SN74LVC07APWR offers tighter propagation delay (2.5 ns) but lacks I_off protection critical for hot-plug systems; 74AHC1G07SE-7 saves area but multiplies component count and assembly cost-making SN74LV07ANS optimal for integrated, power-sequenced 6-channel buffering.

FAQ

What is the maximum sink current capability of the SN74LV07ANS at 3.3-V V_CC?

The SN74LV07ANS delivers up to 8 mA sink current (I_OL) at V_CC = 3 V, per the Electrical Characteristics table in the SCES337K datasheet. This value is confirmed across the full operating temperature range (–40°C to 125°C) and supports reliable driving of standard 3.3-V pull-up networks. The SN74LV07ANS maintains consistent performance without derating at elevated temperatures.

Does the SN74LV07ANS support level translation between 2.5-V and 5-V logic domains?

Yes, the SN74LV07ANS 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. When V_CC = 2.5 V and the output is pulled to 5 V, the SN74LV07ANS correctly buffers the 2.5-V input to a 5-V compatible open-drain signal-enabling seamless interoperation without external translators.

Is the SN74LV07ANS pin-compatible with other SN74LV07A variants like SN74LV07ADR?

Yes, the SN74LV07ANS shares identical pin configuration and function mapping with all SN74LV07A family members-including SN74LV07ADR (SOIC-14), SN74LV07ADBR (SSOP-14), and SN74LV07APWR (TSSOP-14). All variants use the same 14-pin layout with matching 1A–6A inputs, 1Y–6Y open-drain outputs, GND, and V_CC positions, enabling direct PCB footprint reuse across package types.

How does the I_off feature of the SN74LV07ANS protect the system during power-down?

The I_off circuitry in the SN74LV07ANS actively disables all outputs when V_CC drops to 0 V, limiting leakage current to ≤5 µA. This prevents back-current flow from powered downstream circuits (e.g., 5-V buses) into the unpowered SN74LV07ANS, eliminating risk of latch-up or damage during hot-swap events. The SN74LV07ANS maintains this protection across –40°C to 125°C.

What is the recommended bypass capacitor for the V_CC pin of the SN74LV07ANS?

Texas Instruments specifies a 0.1-µF ceramic bypass capacitor placed as close as possible to the V_CC (Pin 14) and GND (Pin 7) pins of the SN74LV07ANS. This value is validated for noise suppression across the 2–5.5-V operating range and is explicitly called out in Section 11 ("Power Supply Recommendations") of the SCES337K datasheet. Larger bulk capacitors (e.g., 1 µF) may be paralleled for enhanced low-frequency filtering.
