Texas Instruments 74LVC2G07MDCKTEPG4

Overview

74LVC2G07MDCKTEPG4 from Texas Instruments is a dual non-inverting buffer/driver with open-drain outputs, designed for 1.65-V to 5.5-V VCC operation. It delivers ±24-mA sink drive at 3.3 V, achieves 5.7 ns max propagation delay at 3.3 V, and supports –55°C to 125°C extended temperature range - enabling robust level-shifting and wired-AND logic in space-constrained industrial control interfaces.

For engineers reviewing the 74LVC2G07MDCKTEPG4 datasheet, 74LVC2G07MDCKTEPG4 pinout, 74LVC2G07MDCKTEPG4 application, or 74LVC2G07MDCKTEPG4 equivalent, key selection criteria include Ioff-enabled partial-power-down capability, 5.5-V tolerant inputs, open-drain output compatibility with external pull-ups, and SC-70 (DCK) package suitability for high-density PCB layouts.

Technical Context

This device implements two independent non-inverting buffers, each with an open-drain output stage that requires an external pull-up resistor to define the high logic level. Its Ioff circuitry actively disables outputs during power-down, blocking current backflow when VCC = 0 V - critical for hot-swap and multi-rail system interoperability.

The input structure accepts voltages up to 5.5 V regardless of VCC level, enabling seamless interfacing between 1.8-V, 3.3-V, and 5-V domains. Output sink current is rated up to 32 mA maximum, with guaranteed VOL ≤ 0.55 V at IOL = 24 mA and VCC = 4.5 V, ensuring reliable low-state voltage margins under load.

FAQ

What is the maximum sink current supported by each output of the 74LVC2G07MDCKTEPG4?

The 74LVC2G07MDCKTEPG4 supports up to 32 mA maximum sink current per open-drain output, verified across the full VCC range (1.65 V to 5.5 V). At VCC = 4.5 V and IOL = 24 mA, the output voltage (VOL) remains ≤ 0.55 V, ensuring sufficient noise margin for downstream logic or LED loads. This rating applies independently to both 1Y and 2Y outputs.

Does the 74LVC2G07MDCKTEPG4 support partial power-down operation?

Yes, the 74LVC2G07MDCKTEPG4 includes Ioff circuitry that disables both outputs when VCC = 0 V, limiting input/output leakage to ±10 µA maximum. This feature prevents damaging back-current flow in multi-rail systems - for example, when a 5-V peripheral remains powered while the 3.3-V controller domain is shut down. The Ioff specification is fully characterized per JESD 78 Class II.

Can the 74LVC2G07MDCKTEPG4 be used to translate 5-V logic signals to a 1.8-V system?

Yes, the 74LVC2G07MDCKTEPG4 accepts input voltages up to 5.5 V regardless of VCC level, making it suitable for translating 5-V signals into 1.8-V domains. When VCC = 1.8 V, the device maintains valid logic thresholds (VIH = 0.65 × VCC ≈ 1.17 V, VIL = 0.35 × VCC ≈ 0.63 V), and its open-drain outputs can be pulled up to 1.8 V externally - enabling clean, low-risk level shifting without additional components.

What is the propagation delay of the 74LVC2G07MDCKTEPG4 at 3.3 V?

The 74LVC2G07MDCKTEPG4 has a maximum propagation delay (tpd) of 5.7 ns at VCC = 3.3 V ± 0.3 V and TA = 25°C, measured from input transition to output transition under standard load conditions (CL = 30 pF, RL = 500 Ω). This value is guaranteed across the full operating temperature range (–55°C to 125°C), supporting timing-critical applications such as real-time control signaling and high-speed bus arbitration.

Is the 74LVC2G07MDCKTEPG4 compatible with standard SC-70 (DCK) footprint layouts?

Yes, the 74LVC2G07MDCKTEPG4 uses the industry-standard SC-70 (DCK) 6-pin package with 0.65-mm lead pitch, 2.0-mm × 1.25-mm body size, and 1.1-mm max height. Its land pattern matches IPC-7351 recommendations, and TI provides verified board layout files confirming pad dimensions (A0 = 2.41 mm, B0 = 2.41 mm, K0 = 1.2 mm) and stencil aperture design for reliable reflow soldering in high-volume manufacturing.
