Texas Instruments SN74AUP2G17YFPR

Overview

SN74AUP2G17YFPR from Texas Instruments is a dual Schmitt-trigger buffer IC in a 6-ball DSBGA (YFP) package, operating from 0.8 V to 3.6 V with 5.4 ns max propagation delay at 3.3 V, 1.5 pF typical input capacitance, and Ioff support for partial-power-down mode - used in noise-immune signal conditioning for portable battery-powered interfaces.

For engineers reviewing the SN74AUP2G17YFPR datasheet, SN74AUP2G17YFPR pinout, SN74AUP2G17YFPR application, or SN74AUP2G17YFPR equivalent, key selection criteria include hysteresis voltage (ΔVT = 0.79–1.31 V), ultra-low dynamic power (Cpd = 4.3 pF), 3.6-V I/O tolerance, and NanoStar™ packaging for space-constrained PCB layouts.

Technical Context

The SN74AUP2G17YFPR implements two independent non-inverting Schmitt-trigger buffers (Y = A), each with asymmetric input thresholds (VT+ and VT−) enabling robust noise rejection on slow or noisy digital signals. Its AUP logic family delivers rail-to-rail output swing and stable operation across the full 0.8–3.6 V supply range.

It features Ioff circuitry that disables outputs during power-down to prevent backflow current, supports mixed-mode voltage translation via 3.6-V tolerant I/Os, and maintains low undershoot/overshoot (<10% of VCC) for signal integrity in point-to-point interconnects.

FAQ

What is the maximum propagation delay of SN74AUP2G17YFPR at 3.3 V?

The maximum propagation delay (tpd) of SN74AUP2G17YFPR is 5.4 ns at VCC = 3.3 V with CL = 15 pF, measured from input transition (10% to 90%) to output transition (10% to 90%). This value is guaranteed across –40°C to 85°C and reflects worst-case performance under typical load conditions specified in the datasheet.

Does SN74AUP2G17YFPR support partial-power-down operation?

Yes, SN74AUP2G17YFPR includes Ioff circuitry that actively disables outputs when VCC = 0 V, preventing current backflow through the device. This feature is fully characterized and guaranteed per JESD 78 Class II latch-up testing, making SN74AUP2G17YFPR suitable for hot-plug and modular power architectures.

What is the input hysteresis voltage (ΔVT) of SN74AUP2G17YFPR at 3 V supply?

At VCC = 3 V, the input hysteresis voltage (ΔVT = VT+ − VT−) of SN74AUP2G17YFPR is 0.79 V (min) to 1.31 V (max), with typical values of 0.79 V and 1.31 V respectively. This wide hysteresis window ensures reliable noise rejection on slow-rising or noisy input signals without oscillation.

Can SN74AUP2G17YFPR operate below 1.0 V?

Yes, SN74AUP2G17YFPR is fully specified down to 0.8 V VCC, with guaranteed functionality including propagation delay, output drive strength, and Schmitt thresholds across the entire –40°C to 85°C temperature range. This enables direct integration with emerging sub-1V microcontrollers and energy-harvesting systems.

What package type does SN74AUP2G17YFPR use, and what are its dimensions?

SN74AUP2G17YFPR uses a 6-ball DSBGA (YFP) package with 0.4 mm ball pitch, 1.19 mm × 1.13 mm body size, and 0.5 mm maximum height. The package conforms to JEDEC MO-287 variation X2AAF and features Pb-free (SnAgCu) solder bumps with MSL Level-1 rating.
