Texas Instruments SN74AUP1G17YZPR

Overview

SN74AUP1G17YZPR from Texas Instruments is a low-power single Schmitt-trigger buffer in a 5-pin DSBGA package (0.89 mm × 1.39 mm), operating across 0.8 V to 3.6 V supply voltage, delivering 5.1 ns max propagation delay at 3.3 V and supporting partial-power-down via I_off. It enables robust signal conditioning in battery-powered portable systems where slow input transitions or noise immunity are critical - such as USB interface level-shifting or reset signal debouncing in handheld tablets.

For engineers reviewing the SN74AUP1G17YZPR datasheet, SN74AUP1G17YZPR pinout, SN74AUP1G17YZPR application, or SN74AUP1G17YZPR equivalent, key selection criteria include its Schmitt-trigger hysteresis (0.07–1.31 V), ultra-low ICC (0.9 µA max), 3.6-V I/O tolerance for mixed-voltage interfacing, and DSBGA-5 footprint compatibility with space-constrained PCB layouts.

Technical Context

The SN74AUP1G17YZPR implements a noninverting Schmitt-trigger gate with hysteresis (ΔV_T) ranging from 0.07 V at 0.8 V V_CC to 1.31 V at 3.0 V V_CC, enabling reliable switching on slow-rising or noisy signals. Its I_off circuitry ensures outputs enter high-impedance state when V_CC = 0 V, preventing back-current flow during partial power-down sequences.

It features balanced CMOS push-pull output drive (±4 mA at 3.0 V), low input capacitance (1.5 pF typical), and 3.6-V tolerant inputs - allowing interoperability with higher-voltage logic domains while powered from sub-1-V rails. The device is fully characterized from –40°C to +85°C and supports CL = 5–30 pF load conditions.

FAQ

What is the minimum supply voltage for reliable operation of the SN74AUP1G17YZPR?

The SN74AUP1G17YZPR is fully specified from 0.8 V to 3.6 V. At 0.8 V, it maintains functional Schmitt-trigger behavior with VT+ = 0.3 V and VT– = 0.1 V, enabling use in energy-harvesting or single-cell Li-ion systems where supply rails dip below 1.0 V during discharge cycles. Performance metrics like t_pd and I_CC remain guaranteed across this full range per TI's SCES579J datasheet.

Does the SN74AUP1G17YZPR support hot-swapping or partial power-down?

Yes. The SN74AUP1G17YZPR includes I_off circuitry that places both input and output terminals in high-impedance state when V_CC = 0 V, limiting leakage to ≤0.6 µA over temperature. This prevents back-current flow into powered-down subsystems - a requirement for hot-pluggable modules and modular industrial controllers using the SN74AUP1G17YZPR.

Can the SN74AUP1G17YZPR accept 5-V input signals while operating at 1.8 V V_CC?

Yes. The SN74AUP1G17YZPR has 3.6-V I/O tolerance and absolute maximum input rating of 4.6 V, so 5-V signals must be clamped externally (e.g., with series resistor + diode to V_CC) to avoid exceeding VI(max). When driven within spec, it correctly buffers 5-V logic levels into 1.8-V domains without damage or functional loss - a key advantage over standard LVC-family buffers.

What is the typical input hysteresis (ΔV_T) of the SN74AUP1G17YZPR at 3.3 V supply?

At V_CC = 3.3 V and TA = 25°C, the SN74AUP1G17YZPR exhibits ΔV_T = V_T+ – V_T– = 0.79 V (min) to 1.31 V (max), with typical value of ~1.05 V. This wide hysteresis window rejects noise spikes up to ±520 mV around the switching threshold - critical for cleaning up signals from inductive sensors or long PCB traces in electrically noisy environments.

Is the SN74AUP1G17YZPR pin-compatible with other AUP-family single-gate buffers?

Yes - all 5-pin AUP single-gate variants (e.g., SN74AUP1G04, SN74AUP1G14, SN74AUP1G17) share identical YZP DSBGA pinout: Pin A (input), Pin Y (output), Pin V_CC, Pin GND, and Pin N.C. This allows drop-in replacement across logic functions without PCB redesign, provided timing and drive requirements are verified for the specific gate type used in the SN74AUP1G17YZPR application.
