Texas Instruments SN74AUP1G17DRLR

Overview

SN74AUP1G17DRLR from Texas Instruments is a single-channel Schmitt-trigger buffer IC designed for signal conditioning in ultra-low-power portable systems. It features 0.8 V to 3.6 V supply operation, 5.1 ns max propagation delay at 3.3 V, 0.9 µA max ICC, and Ioff support for partial power-down mode - enabling robust noise immunity in battery-powered PC, tablet, and industrial control interfaces.

For engineers reviewing the SN74AUP1G17DRLR datasheet, SN74AUP1G17DRLR pinout, SN74AUP1G17DRLR application, or SN74AUP1G17DRLR equivalent, key selection criteria include its Schmitt-trigger input hysteresis (0.07–1.31 V), 3.6-V I/O tolerance for mixed-voltage interfacing, low 1.5 pF input capacitance, and SOT-5X3 (5-pin) package compatibility with space-constrained PCB layouts.

Technical Context

The SN74AUP1G17DRLR implements a noninverting Schmitt-trigger logic gate with hysteresis defined by VT+ and VT− thresholds that vary with VCC (e.g., VT+ = 1.88–2.29 V, VT− = 0.88–1.24 V at 3 V). Its Ioff circuitry actively disables outputs during power-down, limiting leakage to ≤0.6 µA across −40°C to +85°C.

It delivers balanced CMOS push-pull output drive (±4 mA at 3 V), supports CL up to 30 pF, and maintains stable timing performance across VCC = 0.8–3.6 V - making it suitable for point-to-point signal integrity-critical paths where slow-edge or noisy inputs must be cleaned before downstream logic sampling.

FAQ

What is the maximum operating temperature range for the SN74AUP1G17DRLR?

The SN74AUP1G17DRLR is fully specified for operation from −40°C to +85°C ambient temperature. All electrical characteristics - including propagation delay, input thresholds, and Ioff leakage - are guaranteed across this full industrial temperature range, ensuring reliability in factory automation and outdoor grid infrastructure deployments where thermal cycling occurs.

Does the SN74AUP1G17DRLR support partial power-down mode?

Yes, the SN74AUP1G17DRLR supports partial power-down mode via its Ioff feature. When VCC = 0 V, all inputs and outputs enter a high-impedance state with leakage ≤0.6 µA across −40°C to +85°C. This prevents current backflow into unpowered sections of multi-rail systems - a critical requirement in battery-backed memory retention and hot-swap controller designs using SN74AUP1G17DRLR.

What is the typical input capacitance of the SN74AUP1G17DRLR?

The typical input capacitance (Ci) of the SN74AUP1G17DRLR is 1.5 pF, measured at VCC = 0 V and 3.6 V. This low value minimizes loading on high-impedance signal sources such as crystal oscillator outputs, analog comparator stages, or MEMS sensor interfaces - preserving signal rise/fall times and reducing susceptibility to crosstalk in dense PCB layouts.

Can the SN74AUP1G17DRLR interface with 5-V logic signals?

No, the SN74AUP1G17DRLR does not support 5-V logic inputs. Its absolute maximum input voltage is 4.6 V, and its recommended VI range is 0–3.6 V. While it offers 3.6-V I/O tolerance - allowing safe operation with 3.3-V signals even when VCC = 1.8 V - direct connection to 5-V logic violates absolute maximum ratings and risks permanent damage to the SN74AUP1G17DRLR.

What package type is used for the SN74AUP1G17DRLR?

The SN74AUP1G17DRLR uses the SOT-5X3 (5-pin) package: 1.60 mm × 1.20 mm body size, 0.5-mm lead pitch, and RoHS-compliant construction. This NanoStar™ package provides a 40% smaller footprint than standard SOT-23, enabling high-density routing in space-constrained applications such as ultraportable tablets and smart meter modules where SN74AUP1G17DRLR is deployed.
