Texas Instruments SN74AUP1G07YZPR

Overview

SN74AUP1G07YZPR from Texas Instruments is a single non-inverting buffer with open-drain output, designed for level translation and wired-OR logic in ultra-low-power systems. It operates across 0.8 V to 3.6 V supply, delivers <0.9 µA ICC (max), supports 3.6-V I/O tolerance, and features Ioff for live insertion - used in portable medical sensors and battery-powered interface bridging.

For engineers reviewing the SN74AUP1G07YZPR datasheet, SN74AUP1G07YZPR pinout, SN74AUP1G07YZPR application, or SN74AUP1G07YZPR equivalent, key selection criteria include its 0.8–3.6 V VCC range, open-drain output drive capability up to 20 mA, input hysteresis (250 mV typ), ultra-small DSBGA-5 (YZP) package (0.80 mm × 0.80 mm), and Ioff-enabled partial-power-down operation.

Technical Context

The SN74AUP1G07YZPR implements a CMOS-based single-buffer architecture with an open-drain NMOS output stage, requiring an external pull-up for logic-high assertion. Its input hysteresis (250 mV typ at 3.3 V) enables robust operation with slow or noisy signals, while the Ioff circuit isolates inputs/outputs when VCC = 0 V.

It supports mixed-voltage interfacing: inputs tolerate up to 3.6 V regardless of VCC, enabling down-translation from 3.3-V peripherals to sub-1.2-V microcontrollers. Propagation delay is 2.2 ns (typ) at 3.3 V with 5-pF load, and dynamic power dissipation is only 1 pF (Cpd) at 10 MHz.

Key Specifications

Pinout & Package

SN74AUP1G07YZPR uses the YZP package: a 5-pin DSBGA (Die Size Ball Grid Array) with 0.4-mm pitch, 0.80 mm × 0.80 mm body size, and bottom-side solder balls. The package is optimized for space-constrained wearables and implantable-grade PCBs.

FAQ

What is the maximum output sink current for SN74AUP1G07YZPR?

The SN74AUP1G07YZPR supports a maximum output sink current (I_OL) of 20 mA under recommended operating conditions. This rating applies across its full 0.8–3.6 V VCC range and ensures reliable driving of LEDs, pull-up resistors in I²C buses, or enable inputs on downstream ICs without exceeding safe thermal limits in the DSBGA-5 package.

Does SN74AUP1G07YZPR support operation below 1.0 V?

Yes, SN74AUP1G07YZPR is fully specified for operation from 0.8 V to 3.6 V. At 0.8 V VCC, it maintains functional logic levels (VIH/VIL), delivers t_pd ≤ 12.2 ns (CL = 5 pF), and draws ICC ≤ 0.9 µA - making it one of few logic buffers qualified for direct integration with sub-1-V microcontrollers and energy-harvesting PMUs.

Can SN74AUP1G07YZPR be used in I²C bus applications?

Yes, SN74AUP1G07YZPR is commonly deployed in I²C systems as a level-shifting buffer or bus extender. Its open-drain output, 3.6-V I/O tolerance, and ability to operate from 0.8 V to 3.3 V allow seamless interfacing between low-voltage masters (e.g., 0.9-V MCUs) and standard 3.3-V slave devices, provided an appropriate pull-up resistor is used on the Y pin.

What is the purpose of the N.C. pin on SN74AUP1G07YZPR?

Pin 1 of SN74AUP1G07YZPR is marked N.C. (No Connection) - it has no internal bond wire or silicon connection. Per TI's layout guidance, this pad may be left unconnected or tied to GND for mechanical stability; it must never be connected to VCC or driven, as it serves no electrical function and has no ESD protection path.

How does the Ioff feature benefit system design with SN74AUP1G07YZPR?

The Ioff feature in SN74AUP1G07YZPR disables all input/output paths when VCC = 0 V, preventing damaging back-current flow from live signal lines into a powered-down subsystem. This enables safe live insertion of modules, supports partial-power-down modes in portable diagnostics equipment, and eliminates need for external isolation switches in multi-rail sensor hubs.
