Product details
Overview
SN74LVC1G17DBVRG4 from Texas Instruments is a single Schmitt-trigger buffer IC designed for 1.65V to 5.5V operation, delivering 24mA output drive at 3.3V, 4.6ns max propagation delay, and 5.5V-tolerant inputs - used in noise-immune signal conditioning for consumer audio and display interfaces.
For engineers reviewing the SN74LVC1G17DBVRG4 datasheet, SN74LVC1G17DBVRG4 pinout, SN74LVC1G17DBVRG4 application, or SN74LVC1G17DBVRG4 equivalent, key selection criteria include input hysteresis (ΔVT = 0.64V at 3V), Ioff-enabled live insertion support, ±24mA drive capability, and SOT-23-5 (DBV) package compatibility with standard pick-and-place assembly.
Technical Context
The SN74LVC1G17DBVRG4 implements a non-inverting Schmitt-trigger buffer (Y = A) with asymmetric input thresholds: VT+ = 1.48V and VT– = 0.89V at VCC = 3V, yielding 0.59V hysteresis. This enables reliable noise rejection on slow-rising or noisy digital signals without external RC components.
It supports partial-power-down via Ioff circuitry, blocking current flow when VCC = 0V, and operates across –40°C to 125°C with full 5.5V input tolerance independent of supply voltage - critical for level-shifting between mixed-voltage domains in portable electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - enables direct interface with 1.8V, 2.5V, 3.3V, and 5V logic systems |
| Input Hysteresis (ΔVT) | 0.59V at 3V - rejects up to ~590mV of input noise without false triggering |
| tpd Max | 4.6ns at 3.3V, CL = 15pF - supports clean signal buffering up to ~100MHz edge rates |
| Output Drive | ±24mA at 3.3V - drives multiple LVC loads or light capacitive traces without external buffers |
| Ioff Current | ±10μA at VCC = 0V - prevents back-drive damage during hot-swap or power sequencing |
| ESD Rating | ±2000V HBM - meets industrial handling requirements without additional protection circuitry |
| ICC Max | 10μA - negligible quiescent power impact in battery-powered always-on nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVR | Same silicon, identical electrical specs; differs only in lead finish (NIPDAU vs. SN in some variants) and packaging tape/reel size | No functional difference; suitable for same designs requiring SOT-23-5 footprint and 1.65–5.5V operation | Select SN74LVC1G17DBVR for standard NIPDAU finish and 3000-unit reel; SN74LVC1G17DBVRG4 is functionally identical with verified RoHS compliance. |
| 74LVC1G17GW,125 | NXP variant in SC-70-5 (SOT353) package; same VCC range and hysteresis but 5.2ns tpd at 3.3V and ±24mA drive | Smaller 2.1mm × 2.0mm footprint; requires re-layout due to different pinout (pin 1 = GND, pin 2 = A, pin 3 = Y, pin 4 = NC, pin 5 = VCC) | Choose 74LVC1G17GW,125 only when board area is constrained and SC-70-5 placement is validated; not pin-compatible with DBV. |
Compared with SN74LVC1G17DBVR, SN74LVC1G17DBVRG4 offers identical performance with enhanced RoHS traceability; versus 74LVC1G17GW,125, it provides proven SOT-23-5 manufacturability and broader distributor availability, though at slightly larger board area.

FAQ
What is the input hysteresis voltage of the SN74LVC1G17DBVRG4 at 3.3V supply?
The SN74LVC1G17DBVRG4 exhibits 0.59V hysteresis (ΔVT = VT+ − VT−) at VCC = 3.3V, with VT+ = 1.92V and VT− = 1.33V. This value is measured under recommended operating conditions and ensures reliable noise margin for signals with up to ~590mV of superimposed interference. The hysteresis remains stable across –40°C to 125°C.
Can the SN74LVC1G17DBVRG4 be used for level translation from 5V to 3.3V logic?
Yes, the SN74LVC1G17DBVRG4 supports level translation: its inputs tolerate up to 5.5V regardless of VCC, allowing a 5V signal to drive the A input while VCC is set to 3.3V. The output Y then swings rail-to-rail between 0V and 3.3V, providing clean 5V-to-3.3V down-translation without external components - confirmed in TI's Application Note SCBA199.
Does the SN74LVC1G17DBVRG4 require external pull-up or pull-down resistors on its input?
No, the SN74LVC1G17DBVRG4 does not require external biasing on the A input. Its Schmitt-trigger input has defined VT+ and VT− thresholds across the full VCC range, and all unused inputs must be tied to VCC or GND per TI's design guidelines - but the single input on SN74LVC1G17DBVRG4 is actively driven in normal operation, eliminating floating-state risk.
What is the maximum operating frequency supported by the SN74LVC1G17DBVRG4?
The SN74LVC1G17DBVRG4 does not specify a clock frequency limit, but its 4.6ns max propagation delay at 3.3V supports clean edge transmission up to ~100MHz for typical 15pF loads. System-level bandwidth depends on trace capacitance and load; TI application note SCBA199 confirms reliable operation with 100MHz square waves into 15pF + 50Ω.
Is the SN74LVC1G17DBVRG4 compatible with lead-free reflow processes?
Yes, the SN74LVC1G17DBVRG4 carries MSL Level-1 rating with peak reflow temperature up to 260°C, fully compliant with IPC/JEDEC J-STD-020. Its NiPdAu lead finish ensures robust wetting and intermetallic formation during standard lead-free soldering profiles, and TI's packaging documentation confirms suitability for both wave and reflow assembly.
