Texas Instruments SN74LVC1G07DSF2

Overview

SN74LVC1G07DSF2 from Texas Instruments is a single non-inverting buffer/driver with open-drain output, designed for 1.65V–5.5V V_CC operation. It delivers 32mA sink current at 4.5V, supports 5.5V-tolerant inputs/outputs, and achieves 4.2ns max propagation delay at 3.3V - enabling wired-OR logic and level translation in space-constrained consumer audio and embedded interfaces.

For engineers reviewing the SN74LVC1G07DSF2 datasheet, SN74LVC1G07DSF2 pinout, SN74LVC1G07DSF2 application, or SN74LVC1G07DSF2 equivalent, key selection criteria include open-drain drive capability, I_off partial-power-down support, 0.5mm-pitch X2SON-6 package compatibility, and 5.5V input tolerance across 1.65–5.5V supply range.

Technical Context

The SN74LVC1G07DSF2 implements a CMOS-based open-drain buffer with no internal pull-up; external pull-up is required for active-high logic. Its I_off circuitry disables outputs when V_CC = 0V, preventing back-drive during live insertion or partial power-down.

It operates across –40°C to 125°C (except DSBGA variants), supports voltage translation both up and down, and maintains 5.5V input/output tolerance independent of V_CC, enabling interoperability between mixed-voltage domains such as 1.8V logic driving 5V bus lines.

Key Specifications

Pinout & Package

The SN74LVC1G07DSF2 uses a 6-pin X2SON (DSF) package with 1.0mm × 1.0mm body size and 0.5mm pitch. No exposed thermal pad; bottom-side terminals only.

FAQ

What is the maximum sink current supported by the SN74LVC1G07DSF2?

The SN74LVC1G07DSF2 supports up to 32mA sink current at V_CC = 4.5V, as specified in the Absolute Maximum Ratings table. This value is validated across –40°C to 125°C and enables direct driving of LEDs, MOSFET gates, or wired-OR bus lines without external amplification. The SN74LVC1G07DSF2 maintains this rating under recommended operating conditions with proper thermal management.

Does the SN74LVC1G07DSF2 require an external pull-up resistor?

Yes, the SN74LVC1G07DSF2 has an open-drain output and requires an external pull-up resistor to establish a defined logic-high voltage level. The resistor value depends on bus capacitance, rise time requirements, and supply voltage - typical values range from 1kΩ to 10kΩ. Without it, the Y output remains floating in the high state, making the SN74LVC1G07DSF2 non-functional in active-high configurations.

Can the SN74LVC1G07DSF2 operate with a 1.8V supply?

Yes, the SN74LVC1G07DSF2 is fully specified for 1.65V to 5.5V V_CC operation. At 1.8V, it delivers guaranteed 4mA sink current with 8.3ns max propagation delay (–40°C to 85°C), supporting low-power modes in portable devices. Input thresholds scale with V_CC, and 5.5V-tolerant inputs allow interfacing with higher-voltage sources even at 1.8V supply - a key feature of the SN74LVC1G07DSF2.

How does the I_off feature work in the SN74LVC1G07DSF2?

The I_off circuitry in the SN74LVC1G07DSF2 automatically disables all outputs when V_CC = 0V, limiting leakage current to ±10µA. This prevents damaging back-current flow from live inputs or outputs into a powered-down system - essential for hot-plug applications like audio docks or modular SSD enclosures. The SN74LVC1G07DSF2 maintains this protection across full temperature range without external biasing.

What is the thermal resistance (R_θJA) of the SN74LVC1G07DSF2 package?

The SN74LVC1G07DSF2 has a junction-to-ambient thermal resistance (R_θJA) of 439°C/W, measured per JEDEC JESD51 standards. This value assumes standard PCB layout with 1-inch² copper pour. For high-current or high-temperature applications, designers should verify junction temperature using R_θJA, power dissipation (C_pd = 6pF at 5V), and ambient conditions - as thermal performance directly impacts long-term reliability of the SN74LVC1G07DSF2.
