Texas Instruments SN74AUC1G17YZPR

Overview

SN74AUC1G17YZPR from Texas Instruments is a single Schmitt-trigger buffer IC designed for sub-1-V to 2.7-V operation, optimized at 1.8 V with 2.4 ns max propagation delay, ±8-mA output drive, and Ioff partial-power-down support. It performs Y = A logic buffering with hysteresis (ΔVT ≥ 0.37 V at 1.65 V), enabling noise-immune signal conditioning in portable audio and SSD timing paths.

For engineers reviewing the SN74AUC1G17YZPR datasheet, SN74AUC1G17YZPR pinout, SN74AUC1G17YZPR application, or SN74AUC1G17YZPR equivalent, key selection criteria include its DSBGA-5 (1.75 mm × 1.25 mm) NanoFree™ package, 1.65–1.95-V nominal VCC range, 3.6-V I/O tolerance, latch-up immunity (>100 mA), and ESD robustness (2000-V HBM).

Technical Context

The SN74AUC1G17YZPR implements a noninverting Schmitt-trigger buffer with asymmetric input thresholds: VT+ = 0.79–1.16 V and VT– = 0.39–0.62 V at 1.65 V, yielding ≥0.37 V hysteresis. Its Ioff circuitry disables outputs during power-down to prevent back-drive current, supporting mixed-voltage system interconnects.

Operating from 0.8 V to 2.7 V, it delivers rail-to-rail output swing (VOH ≥ VCC – 0.1 V, VOL ≤ 0.45 V at 1.65 V) with 10 µA max ICC and 3 pF typical input capacitance. The device is fully characterized for CL = 15 pF and CL = 30 pF loads, with tpd scaling from 1.9 ns (1.8 V, 15 pF) to 2.4 ns (1.8 V, 30 pF).

FAQ

What is the minimum operating voltage for SN74AUC1G17YZPR?

The SN74AUC1G17YZPR operates down to 0.8 V VCC, with full functionality specified across 0.8–2.7 V. At 0.8 V, it maintains valid logic thresholds (VT+ = 0.5 V, VT– = 0.3 V) and delivers 0.7-mA output drive - making SN74AUC1G17YZPR suitable for energy-harvesting and ultra-low-power microcontroller interfaces.

Does SN74AUC1G17YZPR support I/O voltage translation?

Yes, SN74AUC1G17YZPR supports 3.6-V tolerant I/O while operating from as low as 0.8 V VCC. This allows direct interfacing between 1.8-V logic domains and 3.3-V peripherals without external level shifters - a key feature confirmed in the Recommended Operating Conditions table of the SN74AUC1G17YZPR datasheet.

What is the thermal resistance (RθJA) of SN74AUC1G17YZPR in its DSBGA package?

The SN74AUC1G17YZPR in the YZP (DSBGA-5) package has a junction-to-ambient thermal resistance of 132°C/W, measured under standard JEDEC conditions. This value is significantly lower than competing SOT-23 (206°C/W) and SC70 (252°C/W) variants, enabling higher sustained output drive in thermally dense layouts.

How does the Schmitt-trigger action benefit SN74AUC1G17YZPR in noisy environments?

The SN74AUC1G17YZPR provides ≥0.37 V hysteresis at 1.65 V, meaning input signals must cross VT+ (e.g., 0.79 V) to assert and VT– (e.g., 0.39 V) to deassert. This 370-mV window rejects noise spikes and slow edge rates - critical for reliable operation on long traces or near switching regulators in portable audio and tablet designs.

Is SN74AUC1G17YZPR pin-compatible with other members of the SN74AUC1Gxx family?

No - SN74AUC1G17YZPR is functionally and physically unique within its family. While other variants (e.g., SN74AUC1G00, SN74AUC1G04) share the same YZP-5 package outline, their logic functions and pinouts differ. The SN74AUC1G17YZPR pinout (A, GND, NC, Y, VCC) is specific to the Schmitt-trigger buffer function and not interchangeable with inverters or NAND gates.
