Texas Instruments SN74AUP1G07DRLR

Overview

SN74AUP1G07DRLR from Texas Instruments is a single non-inverting buffer with open-drain output, designed for low-voltage logic translation and level-shifting in battery-powered systems. It operates across 0.8 V to 3.6 V supply, delivers <0.9 µA quiescent current, achieves ≤3.3 ns propagation delay at 3.3 V, and supports Ioff for live insertion-enabling use in portable medical sensors and USB peripheral interfaces.

For engineers reviewing the SN74AUP1G07DRLR datasheet, SN74AUP1G07DRLR pinout, SN74AUP1G07DRLR application, or SN74AUP1G07DRLR equivalent, key selection criteria include its ultra-low ICC, open-drain compatibility with wired-AND bus topologies, 0.8 V minimum VCC support, and SOT-5X3 package footprint optimized for space-constrained PCB layouts.

Technical Context

The SN74AUP1G07DRLR implements a CMOS-based single-buffer architecture with no internal pull-up; its open-drain output requires external pull-up for logic-high assertion. Input hysteresis (250 mV typ at 3.3 V) enables robust operation with slow-rising signals and noise immunity in mixed-signal environments.

It features Ioff circuitry that disables outputs when VCC = 0 V, preventing back-drive current during partial power-down-critical for hot-pluggable modules and multi-rail systems. The device is fully specified from –40°C to +85°C and supports 3.6-V I/O tolerance regardless of VCC, enabling safe interfacing between 1.2-V microcontrollers and 3.3-V peripherals.

FAQ

What is the maximum output sink current specification for SN74AUP1G07DRLR?

The SN74AUP1G07DRLR supports a continuous output sink current of ±20 mA per output terminal. This rating applies under recommended operating conditions (VCC = 0.8 V to 3.6 V, TA = –40°C to +85°C) and ensures reliable driving of LEDs, small relays, or multiple CMOS inputs without derating. Exceeding this limit risks thermal overstress or parametric shift.

Does SN74AUP1G07DRLR support true bidirectional level shifting?

No, the SN74AUP1G07DRLR is a unidirectional buffer with open-drain output and does not support automatic bidirectional translation like dedicated I²C bus buffers. Its input accepts 0–3.6 V regardless of VCC, but output logic state depends solely on the external pull-up voltage-making it ideal for controlled one-way signal translation (e.g., MCU GPIO to 3.3-V interrupt line), not passive bus arbitration.

Can SN74AUP1G07DRLR operate at 0.8 V supply while driving a 3.3-V pull-up?

Yes, SN74AUP1G07DRLR supports 3.6-V I/O tolerance on both input and output pins, allowing its open-drain Y pin to be pulled up to 3.3 V even when VCC = 0.8 V. This enables seamless down-translation from 3.3-V domains to ultra-low-voltage microcontrollers-verified per datasheet Section 7.3 Recommended Operating Conditions and Absolute Maximum Ratings.

Is the NC pin on SN74AUP1G07DRLR electrically connected internally?

No, Pin 1 of SN74AUP1G07DRLR is designated NC (No Connection) and has no internal bond wire or silicon connection. It must remain unconnected on the PCB-neither tied to GND nor VCC-and serves no electrical or thermal function. This is confirmed in the Pin Functions table (Section 6) of the SCES591J datasheet.

How does the Ioff feature of SN74AUP1G07DRLR protect system-level interconnects?

The Ioff feature in SN74AUP1G07DRLR disables all output paths when VCC = 0 V, blocking current flow from powered downstream circuits (e.g., 3.3-V bus) back into the unpowered IC. This prevents damage during hot-swap events, supports partial power-down modes in modular systems, and eliminates the need for external isolation components-validated per JESD78 Class II latch-up testing and TI application report SBAA272.
