Texas Instruments SN74LVC1G07MDCKREP

Overview

SN74LVC1G07MDCKREP 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 operates across –55°C to 125°C for rugged industrial and aerospace applications.

For engineers reviewing the SN74LVC1G07MDCKREP datasheet, SN74LVC1G07MDCKREP pinout, SN74LVC1G07MDCKREP application, or SN74LVC1G07MDCKREP equivalent, key selection criteria include open-drain logic level translation, 5.7 ns max propagation delay at 3.3 V, 32 mA max sink current, Ioff-enabled backflow protection, and SC-70 (DCK) 5-pin package compatibility with space-constrained PCB layouts.

Technical Context

This device implements a single-channel non-inverting logic buffer whose output stage lacks an internal pull-up, requiring external termination for high-level assertion. Its open-drain architecture enables wired-OR logic and level-shifting between mixed-voltage domains (e.g., 1.8-V input to 5-V bus).

The Ioff feature actively disables output leakage when VCC = 0 V, preventing destructive current flow in partial-power-down systems. Input tolerance up to 5.5 V and output voltage rating to 6.5 V allow interfacing with higher-voltage peripherals without level shifters.

FAQ

What is the maximum sink current capability of the SN74LVC1G07MDCKREP at 3.3 V?

The SN74LVC1G07MDCKREP provides up to 24 mA sink current at 3.3 V VCC, as specified in the Electrical Characteristics table under IOL test conditions. This value ensures reliable driving of standard logic inputs, small-signal MOSFETs, or indicator LEDs without external amplification. The SN74LVC1G07MDCKREP maintains this performance across its full operating temperature range of –55°C to 125°C.

Does the SN74LVC1G07MDCKREP support level shifting between different supply voltages?

Yes, the SN74LVC1G07MDCKREP supports level shifting via its 5.5-V tolerant inputs and open-drain output. When powered from a lower VCC (e.g., 1.8 V), it can accept 3.3-V or 5-V input signals and drive a pull-up to a higher voltage rail (e.g., 5 V), enabling bidirectional voltage translation in I²C or SMBus applications. The SN74LVC1G07MDCKREP does not require direction control or external biasing for this function.

Can the SN74LVC1G07MDCKREP be used in partial-power-down systems?

Yes, the SN74LVC1G07MDCKREP incorporates Ioff circuitry that disables output leakage when VCC = 0 V, limiting current to ±10 µA even with input or output voltages present. This feature protects upstream and downstream circuitry during hot-swap or multi-rail sequencing events. The SN74LVC1G07MDCKREP is explicitly characterized for partial-power-down operation across its full –55°C to 125°C temperature range.

What is the propagation delay of the SN74LVC1G07MDCKREP at 5 V VCC?

At 5 V VCC and TA = 25°C, the SN74LVC1G07MDCKREP exhibits a maximum propagation delay (tpd) of 4.9 ns, as documented in the Switching Characteristics table. This value applies to both rising and falling edges due to its open-drain structure and ensures timing predictability in high-speed control loops and clock distribution paths. The SN74LVC1G07MDCKREP maintains consistent delay behavior across its full operating temperature range.

Is the NC pin on the SN74LVC1G07MDCKREP required to be tied to ground or left floating?

The NC (No Connect) pin on the SN74LVC1G07MDCKREP is internally unconnected and must remain electrically floating - it should not be tied to GND, VCC, or any other node. TI's mechanical drawings and layout guidelines confirm this pin has no internal bond wire or circuit connection. Leaving the SN74LVC1G07MDCKREP NC pin floating avoids unintended parasitic coupling or thermal stress in the SC-70 package.
