Texas Instruments SN74AUP1G07DBVRE4

Overview

SN74AUP1G07DBVRE4 from Texas Instruments is a single non-inverting buffer with open-drain output, designed for low-voltage logic translation and level-shifting applications across 0.8 V to 3.6 V supply rails. It delivers ultra-low static current (ICC ≤ 0.9 µA), 3.3 ns max propagation delay at 3.3 V, and Ioff support for live insertion and partial-power-down operation. It is used in battery-powered portable systems such as blood pressure monitors and CPAP machines where power efficiency and signal integrity are critical.

For engineers reviewing the SN74AUP1G07DBVRE4 datasheet, SN74AUP1G07DBVRE4 pinout, SN74AUP1G07DBVRE4 application, or SN74AUP1G07DBVRE4 equivalent, key selection criteria include its open-drain topology for wired-OR bus interfacing, 0.8–3.6 V operating range, Ioff-enabled back-drive protection, and SOT-23 (DBV) 5-pin package compatibility with space-constrained PCB layouts.

Technical Context

The SN74AUP1G07DBVRE4 implements a CMOS-based single-buffer architecture with an open-drain output stage, requiring an external pull-up resistor to define high-level logic states. Its input hysteresis (250 mV typ at 3.3 V) improves noise immunity against slow or noisy transitions, while its Ioff circuitry isolates inputs/outputs when VCC = 0 V-enabling safe hot-plug operation in mixed-voltage systems.

It supports bidirectional voltage translation via open-drain configuration: a 1.2-V microcontroller output can drive a 3.3-V bus by pulling down through SN74AUP1G07DBVRE4, with the 3.3-V pull-up defining VOH. Dynamic power consumption remains minimal (Cpd = 1 pF typ at 3.3 V), and input capacitance is only 1.5 pF, reducing loading on driving sources.

FAQ

What is the maximum output sink current for SN74AUP1G07DBVRE4?

The SN74AUP1G07DBVRE4 supports up to ±20 mA continuous output sink current per Y pin under recommended operating conditions. This rating applies across the full 0.8–3.6 V VCC range and enables direct driving of LEDs, small MOSFET gates, or termination resistors without external amplification. Exceeding this limit risks parametric shift or reliability degradation.

Does SN74AUP1G07DBVRE4 support level translation between different supply domains?

Yes, SN74AUP1G07DBVRE4 supports bidirectional level translation using its open-drain output: a low-voltage input (e.g., 1.2 V) can pull down a higher-voltage bus (e.g., 3.3 V) via an external pull-up. The device's 3.6-V I/O tolerance and VCC-independent input structure allow safe interfacing across mixed-supply systems without additional components.

Can SN74AUP1G07DBVRE4 be used with floating inputs?

No, SN74AUP1G07DBVRE4 inputs must never be left floating. All unused inputs-including A on this single-gate device-must be tied to VCC or GND to prevent undefined logic states, increased ICC, or potential latch-up. The datasheet explicitly requires this for proper operation and reliability across –40°C to 85°C.

What is the significance of the "E4" suffix in SN74AUP1G07DBVRE4?

The "E4" suffix in SN74AUP1G07DBVRE4 denotes Texas Instruments' green packaging standard: lead-free (Pb-free), RoHS-compliant construction with NiPdAu (NIPDAU) lead finish and moisture sensitivity level (MSL) 1 rating (unlimited floor life at ≤30°C/60% RH). It confirms full compliance with environmental regulations and reflow process requirements.

How does the Ioff feature of SN74AUP1G07DBVRE4 improve system reliability?

The Ioff feature in SN74AUP1G07DBVRE4 disables output buffers when VCC = 0 V, blocking current flow from live I/O lines into the unpowered device. This prevents back-drive damage during hot-swap, partial power-down, or mismatched power sequencing-critical for medical devices like CPAP machines and field transmitters where power domain isolation is mandatory.
