Product details
Overview
SN74LVC1G17QDBVRQ1 from Texas Instruments is an automotive-qualified single Schmitt-trigger buffer IC performing Y = A logic, operating from 1.65V to 5.5V VCC, with 5.5V-tolerant inputs, ±24mA output drive at 3.3V, and 8ns max propagation delay at 3.3V - used for noise-immune signal conditioning in audio dock and SSD power control interfaces.
For engineers reviewing the SN74LVC1G17QDBVRQ1 datasheet, SN74LVC1G17QDBVRQ1 pinout, SN74LVC1G17QDBVRQ1 application, or SN74LVC1G17QDBVRQ1 equivalent, this page delivers verified electrical specs, SOT-23-5 pin mapping, Schmitt-trigger hysteresis values, Ioff partial-power-down behavior, and automotive-grade ESD ratings per AEC-Q100.
Technical Context
The SN74LVC1G17QDBVRQ1 implements a noninverting Schmitt-trigger buffer with asymmetric input thresholds (VT+ and VT−) enabling robust noise rejection on slow-rising or noisy digital signals. Its CMOS design supports voltage translation across 1.65V–5.5V rails while maintaining rail-to-rail output swing.
It features Ioff circuitry that disables outputs and blocks current backflow when VCC = 0V, supporting live insertion and partial-power-down systems. Input hysteresis ranges from 0.26V to 1.32V depending on VCC, and output drive capability scales linearly with supply voltage up to ±32mA at 4.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - enables interoperability across mixed-voltage logic domains including 1.8V, 2.5V, 3.3V, and 5V systems |
| Input Voltage Tolerance | Up to 5.5V - allows interfacing with higher-voltage sources without level-shifting circuitry |
| Max tpd | 8ns at 3.3V, CL = 50pF - supports clean signal buffering up to ~100MHz clock/data rates |
| Ioff | ±25μA at VI/VO = 5.5V, VCC = 0V - prevents back-drive damage during hot-swap or power sequencing |
| Hysteresis ΔVT | 0.40V typical at 3V VCC - provides ≥200mV noise margin against EMI-induced glitches on input lines |
| ESD Rating | ±2000V HBM, ±1000V CDM - meets AEC-Q100-002 and -011 for automotive electronics reliability |
| ICC Max | 20μA - ensures ultra-low static power draw in always-on or battery-backed subsystems |

SOT-23-5 (DBV) package: 2.9mm × 2.8mm body, 1.45mm max height, 5-pin surface-mount with gull-wing leads; RoHS-compliant, NIPDAU lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No internal connection (NC) | Unused pad - must be left floating or grounded per layout guidelines; no electrical function |
| 2 | Input (A) | 5.5V-tolerant Schmitt-trigger input accepting slow/noisy signals; threshold hysteresis improves noise immunity |
| 3 | GND | Ground reference for all internal circuitry and output return path; requires low-impedance PCB connection |
| 4 | Output (Y) | CMOS push-pull output delivering ±24mA at 3.3V; rail-to-rail swing with fast edge rates requiring controlled routing |
| 5 | VCC | Power supply input (1.65–5.5V); requires local 0.1μF bypass capacitor placed adjacent to pin |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DCKRQ1 | SC-70-5 package (2.0mm × 2.1mm), 371.0°C/W RθJA, identical electrical specs and AEC-Q100 qualification | Smaller footprint and higher thermal resistance - suited for space-constrained but thermally managed layouts | Select when board area is critical and thermal derating is acceptable; same pinout but different land pattern |
| MC74VHC1G17DTT1G | Non-automotive grade, wider VCC range (2V–5.5V), lower hysteresis (0.2V typ), no Ioff support | Lacks AEC-Q100 qualification and partial-power-down capability - unsuitable for automotive or hot-swap systems | Use only in commercial-grade consumer audio docks or non-safety-critical industrial controls where cost is prioritized over qualification |
Compared with SN74LVC1G17QDBVRQ1, the DCKRQ1 offers identical functionality in a smaller package with trade-offs in thermal performance, while the MC74VHC1G17DTT1G omits automotive qualification and Ioff, limiting its use to less demanding environments.

FAQ
What is the maximum operating temperature for SN74LVC1G17QDBVRQ1?
The SN74LVC1G17QDBVRQ1 is rated for operation from –40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements for under-hood and enclosed chassis automotive applications. This rating applies to the full specified VCC range (1.65V–5.5V) and all electrical parameters in the datasheet.
Does SN74LVC1G17QDBVRQ1 support level shifting between 5V and 3.3V logic domains?
Yes, SN74LVC1G17QDBVRQ1 supports down-level translation: its inputs tolerate up to 5.5V regardless of VCC, allowing 5V signals to safely drive the device when powered at 3.3V, while the output swings rail-to-rail at the 3.3V supply - eliminating need for discrete resistors or dedicated translators.
How does the Schmitt-trigger input of SN74LVC1G17QDBVRQ1 improve noise immunity?
The SN74LVC1G17QDBVRQ1 uses separate positive-going (VT+) and negative-going (VT−) input thresholds, creating hysteresis (ΔVT). At 3V VCC, typical hysteresis is 0.40V - meaning noise spikes ≤200mV cannot cause unintended state changes, making it ideal for debouncing switches or cleaning noisy sensor outputs.
Can SN74LVC1G17QDBVRQ1 be used in hot-swap applications?
Yes, SN74LVC1G17QDBVRQ1 includes Ioff circuitry that disables outputs and blocks current flow when VCC = 0V. This prevents back-driving of powered circuitry during live insertion, satisfying requirements for modular SSD carriers and field-replaceable AV receiver boards.
What is the recommended bypass capacitor for SN74LVC1G17QDBVRQ1?
A 0.1μF ceramic capacitor is recommended directly between VCC (Pin 5) and GND (Pin 3) on the SN74LVC1G17QDBVRQ1 PCB layout, placed as close as possible to the pins. For systems with multiple nearby logic devices, adding a parallel 1μF capacitor further suppresses low-frequency supply ripple.
