Product details
Overview
SN74LVC1G17DBVTE4 from Texas Instruments is a single Schmitt-trigger buffer IC designed for 1.65V to 5.5V VCC operation, delivering 24mA output drive at 3.3V, 4.6ns max propagation delay, and 5.5V-tolerant inputs. It performs Y = A logic with hysteresis (ΔVT = 0.64V at 3V), enabling robust noise immunity in signal conditioning paths for consumer audio and video interfaces.
For engineers reviewing the SN74LVC1G17DBVTE4 datasheet, SN74LVC1G17DBVTE4 pinout, SN74LVC1G17DBVTE4 application, or SN74LVC1G17DBVTE4 equivalent, key selection criteria include input hysteresis voltage, Ioff support for partial-power-down systems, ultra-small SOT-23-5 footprint, and 125°C operational capability in space-constrained embedded designs.
Technical Context
The SN74LVC1G17DBVTE4 implements a non-inverting Schmitt-trigger buffer using advanced CMOS process technology, with separate positive-going (VT+ = 1.48V) and negative-going (VT– = 0.89V) input thresholds at 3V supply. Its Ioff circuitry actively disables outputs when VCC = 0V, preventing back-drive current and supporting live insertion in hot-swap applications.
This device operates across –40°C to +125°C with full DC and AC specifications validated at 1.65V–5.5V VCC, supports down-translation from 5.5V inputs to lower VCC rails, and maintains low static ICC (≤10μA) while delivering ±24mA drive-enabling direct interface with multiple downstream loads without external buffering.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DCKTE4 | SC70-5 package (1.6mm × 1.6mm); 30% smaller footprint than DBV; identical electrical specs | Better suited for ultra-dense PCB layouts where board area is constrained more than height | Select when minimizing PCB real estate is critical and assembly equipment supports SC70 handling |
| MC74VHC1G17DTT1G | Wider VCC range (2V–5.5V); higher tpd (7.5ns @ 3.3V); no Ioff support | Lacks partial-power-down capability; unsuitable for hot-swap or multi-rail sequencing systems | Choose only for cost-sensitive, non-hot-swap applications where 1.65V operation is not required |

FAQ
What is the maximum operating temperature for SN74LVC1G17DBVTE4?
The SN74LVC1G17DBVTE4 is fully specified from –40°C to +125°C ambient temperature. All electrical characteristics-including propagation delay, output drive, and hysteresis-are guaranteed across this full industrial temperature range, making it suitable for under-hood automotive and high-temperature industrial control applications. Thermal derating is not required up to 125°C when used within recommended operating conditions.
Does SN74LVC1G17DBVTE4 support level translation between different supply voltages?
Yes, SN74LVC1G17DBVTE4 supports down-translation: its inputs tolerate up to 5.5V regardless of VCC (1.65V–5.5V), allowing a 5V signal to safely drive the input while the output swings rail-to-rail relative to the local VCC. This enables robust interfacing between legacy 5V logic and modern 1.8V/2.5V/3.3V systems without external resistors or translators.
What is the purpose of the N.C. pin on SN74LVC1G17DBVTE4?
Pin 4 of SN74LVC1G17DBVTE4 is marked N.C. (No internal connection). It has no electrical function and must remain unconnected. While some designs tie N.C. pins to GND for mechanical stability or thermal relief, TI's datasheet explicitly states no internal bond wire connects to this pin-so routing it to ground is optional and does not affect electrical performance.
How does the Ioff feature of SN74LVC1G17DBVTE4 protect system-level designs?
The Ioff feature in SN74LVC1G17DBVTE4 disables output drivers when VCC = 0V, limiting leakage current to ±10μA. This prevents damaging back-current flow from powered downstream circuits into the unpowered SN74LVC1G17DBVTE4, enabling safe hot insertion, partial power-down modes, and robust power sequencing in modular systems like docking stations or server blades.
Can SN74LVC1G17DBVTE4 drive a 50Ω transmission line directly?
Yes, SN74LVC1G17DBVTE4 can drive a 50Ω transmission line directly at 3.3V: its ±24mA output drive supports a 3.3V swing into 50Ω (66mA theoretical max), delivering sufficient edge rate and signal integrity for short-reach interconnects (<10cm). For longer lines or stricter impedance matching, series termination is recommended-but no external buffer is needed for basic point-to-point links.
