Product details
Overview
SN74LVC1G17YEPR from Texas Instruments is a single-channel Schmitt-trigger buffer IC designed for signal conditioning in noise-prone digital interfaces. It operates from 1.65V to 5.5V VCC, delivers ±24mA output drive at 3.3V, achieves 4.6ns max propagation delay, and features 5.5V-tolerant inputs - enabling level translation in mixed-voltage systems such as USB peripheral interfaces and display timing control.
For engineers reviewing the SN74LVC1G17YEPR datasheet, SN74LVC1G17YEPR pinout, SN74LVC1G17YEPR application, or SN74LVC1G17YEPR equivalent, key selection criteria include Schmitt-trigger hysteresis (0.64V typ at 3V), Ioff support for live insertion, ultra-small X2SON-5 (DPW) package (0.8mm × 0.8mm), and guaranteed operation across –40°C to 125°C.
Technical Context
The SN74LVC1G17YEPR implements a non-inverting Boolean function Y = A with hysteresis-based input thresholding: VT+ = 1.48V and VT– = 0.89V at VCC = 3V, yielding ΔVT = 0.59V. This dual-threshold behavior rejects slow-rising or noisy signals that would cause chatter in standard CMOS buffers.
Its Ioff circuitry actively disables outputs when VCC = 0V, blocking back-drive current up to ±10μA and supporting partial-power-down modes in hot-swap applications. The device maintains rail-to-rail output swing (VOH ≥ VCC – 0.1V, VOL ≤ 0.1V) across its full 1.65V–5.5V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - supports direct interface with 1.8V, 2.5V, 3.3V, and 5V logic domains without level shifters |
| Input Voltage Tolerance | Up to 5.5V - enables down-translation from higher-voltage controllers (e.g., 5V microcontrollers driving 3.3V FPGA I/O) |
| Max Propagation Delay | 4.6ns at VCC = 3.3V, TA = 25°C, CL = 15pF - suitable for signal integrity-critical paths up to ~100MHz clock distribution |
| Output Drive Strength | ±24mA at VCC = 3.3V - drives multiple LVC loads or moderate capacitive loads (e.g., 20pF trace + 2x downstream gate inputs) |
| Hysteresis (ΔVT) | 0.64V typical at VCC = 3V - suppresses false triggering on slow edges or EMI-coupled noise in industrial sensor lines |
| Ioff Current | ±10μA max at VCC = 0V - prevents damaging back-current during board hot-plug or power sequencing |
| ESD Rating (HBM) | ±2000V - meets JEDEC JS-001 Class 2, sufficient for handling in standard ESD-controlled assembly environments |
Pinout & Package
The SN74LVC1G17YEPR is packaged in the X2SON-5 (DPW) package: 0.8mm × 0.8mm body size, 0.5mm pitch, 4 active terminals (1 no-connect), compatible with standard reflow profiles (MSL Level 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No internal connection | Must be left floating or tied to GND/VCC; no electrical function - avoids unintended coupling in high-density layouts |
| 2 (A) | Input | Schmitt-triggered data input; accepts 0–5.5V regardless of VCC; hysteresis ensures clean edge regeneration |
| 3 (GND) | Ground reference | Primary return path for output current and internal logic; requires low-inductance connection to system ground plane |
| 4 (Y) | Output | Non-inverted buffered output; rail-to-rail swing, ±24mA drive capability, supports fanout to multiple LVC inputs |
| 5 (VCC) | Power supply | Core supply pin; requires local 0.1μF ceramic bypass capacitor placed within 2mm of pin to suppress switching noise |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | 0.59V hysteresis at 3V - eliminates metastability on slow analog-like signals (e.g., reset buttons, mechanical switch debouncing) |
| Ioff partial-power-down | Active isolation at VCC = 0V - enables safe insertion into powered-backplane systems without disrupting upstream logic |
| 5.5V-tolerant inputs | Operates with VIN up to 5.5V while VCC = 1.8V - eliminates external level translators in mixed-supply SoC interconnects |
| Ultra-small DPW package | 0.64mm² footprint (0.8mm × 0.8mm) - saves >70% board area vs. SOT-23-5, critical for space-constrained portable audio and SSD modules |
| Low static ICC | 10μA max at 125°C - minimizes quiescent power in always-on subsystems like HDMI CEC receivers or wake-on-LAN circuits |
Applications

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 | SOT-23-5 package (2.9mm × 1.6mm body); same electrical specs and pinout as SN74LVC1G17YEPR | Requires larger PCB footprint; better thermal dissipation (RθJA = 357°C/W vs. 130°C/W for DPW) | Select when manual soldering or legacy layout compatibility is required; not drop-in for DPW footprints. |
| SN74AUP1G17DBVR | Lower VCC range (0.8V–3.6V); 3.7ns tpd at 1.8V; 9μA ICC; smaller hysteresis (0.2V typ) | Optimized for ultra-low-power 1.8V systems; insufficient for 5V-tolerant or 5V supply applications | Choose only for battery-powered 1.8V designs where 5V tolerance is unnecessary and <1μA standby is critical. |
Compared with SN74LVC1G17DBVR, SN74LVC1G17YEPR saves >75% board area but requires tighter reflow control due to smaller pad geometry; versus SN74AUP1G17DBVR, it trades lower ICC for essential 5.5V input tolerance and wider supply flexibility - making it the sole choice for mixed-voltage industrial and consumer interfaces.

FAQ
What is the package type and dimensions of the SN74LVC1G17YEPR?
The SN74LVC1G17YEPR uses the X2SON-5 (DPW) package with a 0.8mm × 0.8mm body size and 0.5mm pin pitch. Its ultra-compact 0.64mm² footprint is optimized for portable electronics. The package has five terminals: pins 1 (NC), 2 (A), 3 (GND), 4 (Y), and 5 (VCC). Thermal resistance is RθJA = 130°C/W, significantly lower than larger alternatives like SOT-23.
Does the SN74LVC1G17YEPR support level translation between different supply voltages?
Yes, the SN74LVC1G17YEPR supports down-translation via 5.5V-tolerant inputs - allowing a 5V signal to safely drive the A input while VCC is as low as 1.65V (e.g., 3.3V or 1.8V). It does not support up-translation: the Y output swings rail-to-rail between GND and VCC, so output voltage is always bounded by the local supply. This makes SN74LVC1G17YEPR ideal for interfacing higher-voltage controllers to lower-voltage peripherals.
What is the hysteresis voltage (ΔVT) of the SN74LVC1G17YEPR and why does it matter?
The SN74LVC1G17YEPR provides 0.64V typical hysteresis (ΔVT = VT+ − VT−) at VCC = 3V, with VT+ = 1.48V and VT− = 0.89V. This hysteresis prevents multiple output transitions when input signals cross the threshold slowly or with noise - critical for reliable debouncing of mechanical switches, noise rejection on long traces, and stable operation in EMI-heavy environments like TV power supplies or audio docks.
Can the SN74LVC1G17YEPR be used in hot-swap or partial-power-down systems?
Yes, the SN74LVC1G17YEPR includes Ioff circuitry that disables outputs and limits input/output leakage to ±10μA when VCC = 0V. This feature protects upstream and downstream circuitry during live insertion or power sequencing events - for example, when plugging an SSD module into a powered host backplane. The Ioff specification is explicitly tested and guaranteed per JESD78 Class II latch-up standards.
What are the absolute maximum ratings for the SN74LVC1G17YEPR?
The SN74LVC1G17YEPR has an absolute maximum VCC of 6.5V and input/output voltage rating of –0.5V to 6.5V. Continuous output current is ±50mA per pin, and total VCC/GND current must not exceed ±100mA. Storage temperature spans –65°C to +150°C. Exceeding these limits may cause permanent damage; recommended operating conditions (1.65V–5.5V VCC, –40°C to +125°C) ensure full functionality and reliability.
