Product details
Overview
SN74LVC2G17QDCKRQ1 from Texas Instruments is an automotive-qualified dual Schmitt-trigger buffer IC operating from 1.65 V to 5.5 V, delivering 5.4 ns max propagation delay at 3.3 V, ±24 mA output drive, and Ioff support for partial-power-down mode. It performs Y = A logic on two independent channels and is used in noise-immune signal conditioning for automotive body control modules, infotainment interfaces, and sensor signal routing.
For engineers reviewing the SN74LVC2G17QDCKRQ1 datasheet, SN74LVC2G17QDCKRQ1 pinout, SN74LVC2G17QDCKRQ1 application, or SN74LVC2G17QDCKRQ1 equivalent, key selection criteria include Schmitt-trigger hysteresis (0.4–1.4 V), automotive temperature range (–40°C to 125°C), SC-70-6 package compatibility, and Ioff-enabled system-level power sequencing.
Technical Context
This device implements two independent noninverting Schmitt-trigger buffers with asymmetric input thresholds: VT+ ranges from 0.7 V (1.65 V VCC) to 3.7 V (5.5 V VCC), while VT– ranges from 0.3 V to 2.5 V, yielding hysteresis (ΔVT) of 0.4–1.4 V. Each channel accepts inputs up to 5.5 V regardless of VCC level.
The Ioff circuitry actively disables outputs during power-down, blocking reverse current flow and enabling hot-insertion capability. Output drive strength scales with VCC: ±24 mA at 3 V, ±32 mA at 4.5 V, with VOL ≤ 0.55 V and VOH ≥ 3.8 V under full load.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G17DBVRQ1 | Same electrical specs; packaged in SOT-23-6 (DBV) with larger footprint (2.9 mm × 1.6 mm) and lower θJA (165°C/W) | Better thermal performance in high-density layouts; less suitable for ultra-compact PCBs | Select DBVRQ1 when board space allows and thermal margin is constrained |
| NC7WZ17P6X | Lower hysteresis (0.2 V typ), no AEC-Q100 qualification, max tpd = 4.5 ns at 3.3 V, operates down to 1.65 V | Not automotive-qualified; suited for industrial or consumer applications requiring faster response | Select NC7WZ17P6X only for non-automotive designs where AEC-Q100 compliance is unnecessary |
Compared with SN74LVC2G17QDCKRQ1, the DBVRQ1 variant offers superior thermal dissipation in space-tolerant layouts, while the NC7WZ17P6X provides faster propagation but lacks automotive qualification and robust hysteresis - making SN74LVC2G17QDCKRQ1 the sole choice for AEC-Q100-compliant noise-critical vehicle subsystems.

The SN74LVC2G17QDCKRQ1 supports input voltages up to 5.5 V regardless of VCC level, enabling direct interfacing with 5-V sensors or microcontrollers without external level-shifting components. This 5.5-V tolerance applies to both 1A and 2A inputs and is specified across the full operating temperature range of –40°C to 125°C.
Does SN74LVC2G17QDCKRQ1 support partial-power-down operation?
Yes, SN74LVC2G17QDCKRQ1 includes Ioff circuitry that disables outputs when VCC = 0 V, limiting reverse current to ±10 µA max. This feature allows safe insertion into live backplanes and enables robust power sequencing in multi-rail automotive ECUs where individual supplies may be powered up/down independently.
What is the typical hysteresis voltage (ΔVT) of SN74LVC2G17QDCKRQ1 at 3.3 V VCC?
At VCC = 3.3 V, the SN74LVC2G17QDCKRQ1 exhibits a typical hysteresis (ΔVT = VT+ – VT–) of 0.9 V, with VT+ = 2.2 V and VT– = 1.3 V. This 0.9 V window provides strong immunity against noise spikes and contact bounce in automotive switch interfaces, ensuring clean, chatter-free digital transitions.
Is SN74LVC2G17QDCKRQ1 qualified for automotive applications?
Yes, SN74LVC2G17QDCKRQ1 is AEC-Q100 Grade 1 qualified (–40°C to 125°C) and explicitly designed for automotive use. It meets stringent requirements for latch-up immunity (>100 mA), ESD robustness (2000-V HBM), and long-term reliability in engine bay and cabin environments.
