Texas Instruments 74LVC1G07MDCKREPG4

Overview

74LVC1G07MDCKREPG4 from Texas Instruments is a single non-inverting buffer/driver with open-drain output, designed for 1.65-V to 5.5-V VCC operation. It delivers ±24-mA sink drive at 3.3 V, supports partial-power-down via Ioff (≤10 μA ICC), and achieves 5.7 ns max propagation delay. It enables wired-OR logic in I²C bus level-shifting applications.

For engineers reviewing the 74LVC1G07MDCKREPG4 datasheet, 74LVC1G07MDCKREPG4 pinout, 74LVC1G07MDCKREPG4 application, or 74LVC1G07MDCKREPG4 equivalent, key selection criteria include open-drain compatibility with 5.5-V tolerant inputs, –55°C to 125°C extended temperature range, and SC-70 (DCK) 5-pin package footprint constraints.

Technical Context

This device implements a single-channel non-inverting logic buffer whose output stage lacks an internal pull-up, requiring external termination. Its Ioff circuitry actively disables output paths during power-down to prevent backflow current, enabling hot-insertion in multi-rail systems.

The input accepts voltages up to 5.5 V independent of VCC, allowing level translation between 1.8-V, 2.5-V, 3.3-V, and 5-V domains. Output sink capability scales with VCC: 16 mA at 3 V, 32 mA at 4.5 V, with VOL ≤ 0.55 V under full load.

FAQ

What is the maximum sink current specification for the 74LVC1G07MDCKREPG4 at 3.3 V?

The 74LVC1G07MDCKREPG4 delivers up to 24 mA sink current (IOL) at VCC = 3.3 V, with VOL guaranteed ≤ 0.55 V. This rating is confirmed in the Electrical Characteristics table under recommended operating conditions and supports direct driving of standard logic inputs or small LEDs without external amplification. The 74LVC1G07MDCKREPG4 maintains this performance across its full operating temperature range.

Does the 74LVC1G07MDCKREPG4 support partial-power-down operation, and how is it implemented?

Yes, the 74LVC1G07MDCKREPG4 supports partial-power-down via its Ioff circuitry. When VCC = 0 V, the Ioff feature disables internal output paths, limiting leakage current to ±10 μA and preventing damaging back-current from live I/O lines. This behavior is verified per JEDEC JESD78 Class II latch-up standards and is critical for hot-swap and multi-rail system designs where the 74LVC1G07MDCKREPG4 may be unpowered while connected to active buses.

Can the 74LVC1G07MDCKREPG4 safely interface a 5-V input signal to a 1.8-V powered microcontroller?

Yes-the 74LVC1G07MDCKREPG4 accepts input voltages up to 5.5 V regardless of VCC level, making it ideal for level translation. When powered at 1.8 V, its A input remains fully compatible with 5-V logic, and its open-drain Y output can be pulled to any voltage up to 5.5 V. This eliminates the need for external level shifters in mixed-voltage systems using the 74LVC1G07MDCKREPG4 as a buffer.

What is the propagation delay of the 74LVC1G07MDCKREPG4, and under what conditions is it specified?

The 74LVC1G07MDCKREPG4 has a maximum propagation delay (tpd) of 5.7 ns at VCC = 3.3 V ± 0.3 V and TA = 25°C, measured from A to Y under CL = 50 pF load. At 5 V, tpd reduces to 4.9 ns. These values are guaranteed across the full –55°C to 125°C operating range per the Switching Characteristics table, ensuring predictable timing in real-time control loops using the 74LVC1G07MDCKREPG4.

Is the 74LVC1G07MDCKREPG4 pin-compatible with other members of the SN74LVC1Gxx series?

No-the 74LVC1G07MDCKREPG4 is functionally and physically specific to the open-drain buffer function and is not pin-compatible with inverters (e.g., SN74LVC1G04), AND gates (e.g., SN74LVC1G08), or other variants in the SN74LVC1Gxx family. While all share the SC-70 (DCK) 5-pin package, pin assignments differ: the 74LVC1G07MDCKREPG4 uses Pin 1 (A), Pin 2 (GND), Pin 3 (Y), Pin 4 (VCC), and Pin 5 (NC), which is unique to this buffer topology.
