Product details

Overview

SN74LVC1G17QDRYRQ1 from Texas Instruments is an automotive-qualified single Schmitt-trigger buffer IC performing Y = A logic, operating from 1.65V to 5.5V V_CC, with 5.5V-tolerant inputs, ±24mA output drive at 3.3V, and 8ns max propagation delay. It enables robust signal conditioning in noisy or slow-rising digital interfaces within infotainment and power management subsystems.

For engineers reviewing the SN74LVC1G17QDRYRQ1 datasheet, SN74LVC1G17QDRYRQ1 pinout, SN74LVC1G17QDRYRQ1 application, or SN74LVC1G17QDRYRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, I_off partial-power-down support, hysteresis (ΔV_T = 0.26–1.32V), 20μA max I_CC, and USON-6 (DRY) package compatibility with space-constrained automotive PCB layouts.

Technical Context

This CMOS Schmitt-trigger buffer implements noise-immune signal reshaping via distinct positive-going (V_T+) and negative-going (V_T−) input thresholds-ranging from 0.23V/0.64V at 1.65V V_CC to 2.53V/3.43V at 5.5V-enabling reliable edge detection on slow or distorted waveforms. Its I_off circuitry actively disables outputs when V_CC = 0V, preventing back-drive current and supporting live insertion.

The device delivers rail-to-rail CMOS output swing with ±24mA drive capability at 3.3V while maintaining low static power (20μA max I_CC). Input overvoltage tolerance up to 5.5V allows level translation from higher-voltage sources into lower-V_CC domains without external components.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65V to 5.5V - supports mixed-voltage system interfacing and battery-backed operation
Propagation Delay (t_pd)	Max 8ns at 3.3V - enables reliable timing in ≤100MHz digital paths
Output Drive	±24mA at 3.3V - drives multiple CMOS loads or moderate capacitive traces without buffering
Hysteresis (ΔV_T)	0.26V–1.32V - rejects noise up to ~1.3V peak-to-peak on input signals
I_off Support	Active at V_CC = 0V - prevents back-current during hot-swap or partial power-down
ESD Rating	±2000V HBM, ±1000V CDM - meets AEC-Q100 stress requirements for automotive environments
Operating Temp	–40°C to +125°C - qualified for under-hood and cabin-mounted automotive electronics

Pinout & Package

SN74LVC1G17QDRYRQ1 uses a 6-pin USON (DRY) package: 1.45mm × 1.0mm body, 0.6mm max height, wettable flank terminals, and exposed thermal pad. Pin 1 is marked by index area; orientation follows Q1 quadrant per tape-and-reel standard.

Pin/Terminal	Circuit Role	Design Meaning
1	A	Schmitt-trigger input - accepts 0–5.5V signals regardless of V_CC
2	N.C.	No internal connection - must be left unconnected or tied to GND/V_CC per layout guidelines
3	N.C.	No internal connection - same as Pin 2; no functional impact if floating
4	GND	Ground reference - connects to system ground plane for noise immunity and thermal dissipation
5	Y	Buffered non-inverting output - delivers full-rail CMOS swing with ±24mA drive
6	V_CC	Power supply - supplies core logic and output drivers; requires local 0.1μF bypass capacitor

Key Features

Feature	Design Value
AEC-Q100 Grade 1 Qualified	Validated for automotive use across –40°C to +125°C ambient, including HTOL and temperature cycling
5.5V Input Tolerance	Enables direct interface with 5V microcontrollers or sensors without level-shifter circuitry
I_off Protection	Prevents damaging current flow during power sequencing mismatches or board hot-plug events
Low ICC (20μA max)	Reduces quiescent power in always-on vehicle modules such as telematics wake-up circuits
USON-6 (DRY) Package	0.6mm profile and 1.45mm × 1.0mm footprint saves PCB area vs. SOT-23/SC-70 alternatives

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G17QDBVRQ1	Same silicon, SOT-23-5 (DBV) package - larger footprint (2.9mm × 2.8mm), no exposed thermal pad	Better suited for manual assembly or legacy layouts; lower thermal performance (R_θJA = 357°C/W vs. 608°C/W)	Select when board rework accessibility or existing DBV land patterns are prioritized over size/power density
SN74LVC1G17QDCKRQ1	Same silicon, SC-70-5 (DCK) package - 2.0mm × 2.1mm body, 5-pin count, no N.C. pins	Higher pin density than DRY but lacks I_off-optimized terminal layout; R_θJA = 371°C/W	Choose for cost-sensitive designs where USON thermal advantages are non-critical and SC-70 tooling exists

Compared with SN74LVC1G17QDRYRQ1, the DBV variant offers easier handling and better thermal conduction via leads, while the DCK version provides intermediate size reduction without the DRY package's ultra-low profile and wettable flanks-making SN74LVC1G17QDRYRQ1 optimal for automated optical inspection and high-density automotive modules.
