Texas Instruments SN74AUP2G07YFPR

Overview

SN74AUP2G07YFPR from Texas Instruments is a dual non-inverting buffer/driver with open-drain outputs, designed for low-voltage logic translation and wired-OR bus interfacing in portable and space-constrained systems. It operates across 0.8 V to 3.6 V, delivers 3.3 ns max propagation delay at 3.3 V, supports Ioff for live insertion, and features 1.5 pF typical input capacitance and 0.9 µA max ICC - enabling ultra-low-power operation in battery-powered medical sensors and embedded peripherals.

For engineers reviewing the SN74AUP2G07YFPR datasheet, SN74AUP2G07YFPR pinout, SN74AUP2G07YFPR application, or SN74AUP2G07YFPR equivalent, key selection criteria include its 0.8–3.6 V supply range, open-drain output compatibility with mixed-voltage buses, Ioff-enabled partial-power-down capability, and DSBGA-6 (1.16 mm × 0.76 mm) footprint for high-density PCB layouts.

Technical Context

The SN74AUP2G07YFPR implements two independent non-inverting buffers with open-drain outputs, requiring external pull-up resistors to define logic-high levels. Its Ioff circuitry actively isolates inputs and outputs when VCC = 0 V, preventing back-drive current and enabling hot-plug functionality in modular systems.

Input hysteresis (250 mV typical at 3.3 V) improves noise immunity against slow-rising signals, while low dynamic power (Cpd = 1 pF typical at 3.3 V) and sub-1-µA static current ensure minimal energy draw in always-on sensor nodes and wearable electronics.

FAQ

What is the maximum output sink current supported by the SN74AUP2G07YFPR?

The SN74AUP2G07YFPR supports a continuous output sink current of ±20 mA per channel, with a total device limit of ±50 mA across both outputs. At VCC = 3.3 V and IOL = 4 mA, the output voltage remains ≤0.45 V, ensuring robust LOW-level margin for standard CMOS loads. Exceeding these ratings risks thermal overstress or degraded VOL performance.

Does the SN74AUP2G07YFPR require external pull-up resistors on its outputs?

Yes, the SN74AUP2G07YFPR has open-drain outputs and cannot drive HIGH states internally. External pull-up resistors are mandatory to define the logic HIGH voltage level. Typical values range from 4.7 kΩ to 10 kΩ for 3.3-V systems, selected based on rise time requirements and bus capacitance - as confirmed in the device's typical application schematic (Figure 9-1).

Can the SN74AUP2G07YFPR operate with a 0.8-V supply voltage?

Yes, the SN74AUP2G07YFPR is fully specified to operate down to 0.8 V, supporting direct integration with emerging ultra-low-voltage microcontrollers and energy-harvesting subsystems. At 0.8 V, propagation delay increases to 12.2 ns (CL = 5 pF), and VOL remains ≤0.1 V at 20 µA load - maintaining functional correctness in deep-sleep sensor nodes.

How does the Ioff feature of the SN74AUP2G07YFPR benefit system design?

The Ioff feature in the SN74AUP2G07YFPR disables input/output circuitry when VCC = 0 V, limiting off-state leakage to ≤0.6 µA. This prevents damaging back-current flow during hot-swap events in modular medical equipment and enables safe partial-power-down in multi-rail embedded systems - a capability not present in standard LVC or AHC logic families.

Is the SN74AUP2G07YFPR compatible with 3.3-V I/O systems despite its 0.8–3.6-V supply range?

Yes, the SN74AUP2G07YFPR is explicitly rated for 3.6-V I/O tolerance, meaning its inputs and outputs safely accept voltages up to 3.6 V regardless of VCC setting. This allows seamless interfacing with 3.3-V peripherals while powered from lower supplies (e.g., 1.8 V), eliminating external level shifters in mixed-voltage designs like smartphone accessory docks and IoT sensor hubs.
