Product details
Overview
SN74LVC2G17YEPR from Texas Instruments is a dual Schmitt-trigger buffer IC designed for 1.65-V to 5.5-V operation, featuring two independent noninverting buffers with hysteresis (ΔVT up to 1.4 V), ±24-mA output drive at 3.3 V, and 5.4-ns max propagation delay. It enables robust signal conditioning in noisy digital interfaces such as I²C bus line buffering and push-button debouncing.
For engineers reviewing the SN74LVC2G17YEPR datasheet, SN74LVC2G17YEPR pinout, SN74LVC2G17YEPR application, or SN74LVC2G17YEPR equivalent, this device is selected for low-voltage logic interfacing where input noise immunity, partial-power-down support (Ioff), and ultra-small WCSP packaging are critical design requirements.
Technical Context
This device implements two independent 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 depending on supply voltage. Each buffer operates with rail-to-rail input tolerance up to 5.5 V and supports Ioff circuitry for backflow prevention during partial power-down.
The SN74LVC2G17YEPR uses NanoFree™ WCSP (YEP package) - a die-size package with six solder bumps - and is specified for –40°C to 85°C operation. Its logic diagram confirms noninverting function Y = A per channel, with no internal enable control or inversion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports mixed-voltage system interfacing without level shifters |
| Max tpd | 5.4 ns at 3.3 V - ensures timing compliance in high-speed 3.3-V logic domains |
| Output Drive | ±24 mA at 3.3 V - drives multiple LVC loads or moderate capacitive traces directly |
| Ioff Current | ±10 µA max - blocks current flow when powered down, enabling safe hot-insertion |
| Hysteresis ΔVT | 0.4 V to 1.4 V - rejects noise spikes up to 1.4 V peak-to-peak on slow or noisy inputs |
| Input Voltage Range | –0.5 V to 5.5 V - accepts overvoltage inputs beyond VCC, simplifying interface design |
| ICC Max | 10 µA - enables ultra-low static power in battery-backed or always-on circuits |
Pinout & Package
NanoFree™ WCSP (YEP) package: 6-bump, 0.23-mm large bump, bottom-side marked with three-character date code + test-site identifier; pin 1 identified by SnPb composition marker ('1').
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Channel 1 input | Noninverting Schmitt-trigger input; accepts 0–5.5 V regardless of VCC |
| GND | Ground reference | Common return path for both channels; must be low-impedance for noise immunity |
| 2A | Channel 2 input | Independent noninverting Schmitt-trigger input; electrically isolated from 1A |
| 1Y | Channel 1 output | Noninverting buffered output; drives loads up to ±24 mA at 3.3 V |
| VCC | Supply voltage | Single supply for both buffers; powers internal Schmitt circuitry and output stage |
| 2Y | Channel 2 output | Independent noninverting buffered output; shares VCC/GND but no internal coupling |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs with programmable hysteresis | ΔVT up to 1.4 V enables reliable switching on slow-rising signals like mechanical switches or RC networks |
| Ioff partial-power-down support | Prevents damaging back-current when VCC = 0 while inputs remain active - essential for hot-swap systems |
| Rail-to-rail input tolerance (–0.5 V to 5.5 V) | Eliminates need for external clamping diodes when interfacing with 5-V legacy signals |
| NanoFree™ WCSP (YEP) package | 0.23-mm bump height improves solder joint reliability vs. YEA/YZA; die-size footprint saves PCB area |
| ESD protection | 2000-V HBM and 1000-V CDM - exceeds JEDEC standards for handling in automated assembly |
Applications
| Industrial Push-Button Interface | I²C Bus Signal Conditioning |
|---|---|
Use Scenario: Mechanical push-button connected to microcontroller GPIO with long PCB traces in factory automation panels. IC Role / Device Role / Timing Role: Dual Schmitt-trigger buffer conditioning noisy switch bounce into clean digital edges. Use Value: ΔVT ≥ 0.7 V rejects EMI-induced glitches on 10-cm traces; Ioff prevents backfeed when MCU is asleep. |
Use Scenario: Level-shifting and noise filtering between 3.3-V MCU and 5-V I²C peripheral with long bus runs. IC Role / Device Role / Timing Role: Noninverting buffer isolating and strengthening SDA/SCL lines without adding propagation delay skew. Use Value: 5.4-ns max tpd preserves I²C timing margins; 5.5-V-tolerant inputs accept 5-V pull-ups directly. |
| Low-Power Sensor Node Input Stage | USB-C CC Line Debounce |
Use Scenario: Battery-powered environmental sensor node receiving analog comparator outputs or reed-switch alerts. IC Role / Device Role / Timing Role: Low-IQ Schmitt buffer converting slow, noisy comparator transitions into clean wake-up interrupts. Use Value: 10-µA ICC extends battery life; 1.65-V min VCC allows operation down to single Li-ion cell voltage. |
Use Scenario: USB-C port controller detecting plug insertion via CC pin voltage transitions with contact bounce. IC Role / Device Role / Timing Role: Dual-channel Schmitt buffer cleaning CC line voltage steps before USB PD state machine sampling. Use Value: Independent channels process CC1/CC2 simultaneously; hysteresis eliminates false attach/detach events. |
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 |
|---|---|---|---|
| SN74LVC2G17YZPR | Pb-free NanoFree™ WCSP (YZP); identical electrical specs and pinout; same 0.23-mm bump height | RoHS-compliant alternative with SNAGCU finish; suitable for new designs requiring lead-free assembly | Select YZPR for RoHS-compliant production; YEP retains SnPb for legacy reflow compatibility |
| SN74LVC2G17DBVR | SOT-23-6 package (DBV); same logic function and specs, but larger footprint and higher θJA (165°C/W) | Better thermal margin in high-ambient environments; easier manual prototyping and rework | Choose DBVR when board space permits and hand-soldering or thermal testing is required |
Compared with SN74LVC2G17YEPR, YZPR offers identical performance in a Pb-free package for compliance-driven programs, while DBVR provides proven manufacturability in standard SOT-23 - neither is pin-compatible due to differing package geometries, but all share identical logic behavior and DC/AC specifications.

FAQ
What is the operating temperature range for SN74LVC2G17YEPR?
The SN74LVC2G17YEPR is rated for operation from –40°C to +85°C ambient temperature. This range is validated per JEDEC JESD78 latch-up testing and JESD22 ESD stress conditions, ensuring reliability in industrial control panels and outdoor sensor enclosures where thermal cycling occurs.
Does SN74LVC2G17YEPR support 5-V input signals when powered from 3.3 V?
Yes, SN74LVC2G17YEPR accepts input voltages from –0.5 V to 5.5 V independent of VCC, so it safely buffers 5-V signals while operating at 3.3 V. This eliminates external level-shifter components in mixed-voltage systems such as 3.3-V MCUs communicating with 5-V peripherals.
How does the Schmitt-trigger hysteresis of SN74LVC2G17YEPR improve noise immunity?
The SN74LVC2G17YEPR provides hysteresis (ΔVT) from 0.4 V to 1.4 V depending on VCC, meaning its positive-going threshold (VT+) and negative-going threshold (VT–) differ significantly. This prevents multiple toggles on slowly changing or noisy inputs - for example, rejecting >1-V peak-to-peak noise on push-button lines without software debouncing.
Is SN74LVC2G17YEPR pin-compatible with other packages in the SN74LVC2G17 family?
No - SN74LVC2G17YEPR uses the NanoFree™ WCSP YEP package with bottom-side bump layout, while DBV (SOT-23) and DCK (SC-70) variants have different pinouts and physical footprints. Though functionally identical, PCB layout must be redesigned when switching between YEP and surface-mount packages.
What is the maximum output current capability of SN74LVC2G17YEPR at 3.3 V?
At VCC = 3.3 V, SN74LVC2G17YEPR delivers ±24 mA per output (IOL = 24 mA, IOH = –24 mA), sufficient to drive four LVC loads or moderate capacitive loads (<50 pF) without external buffers. This rating is guaranteed across the full –40°C to 85°C temperature range.
