Product details
Overview
SN74LVC3G17DCTRE4 from Texas Instruments is a triple 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-enabled live insertion support. It performs Y = A logic across three independent channels and is used in audio docks, SSDs, and portable tablets for noise-immune signal conditioning.
For engineers reviewing the SN74LVC3G17DCTRE4 datasheet, SN74LVC3G17DCTRE4 pinout, SN74LVC3G17DCTRE4 application, or SN74LVC3G17DCTRE4 equivalent, key selection factors include its 8-pin SSOP (DCT) package, Schmitt-trigger hysteresis (ΔVT = 0.56–1.11 V), 10-μA max ICC, overvoltage-tolerant inputs (to 5.5 V), and partial-power-down capability via Ioff.
Technical Context
This device implements three noninverting Schmitt-trigger buffers with separate input threshold levels for rising (VT+) and falling (VT–) edges-enabling robust noise rejection in slow or noisy digital signals. Each channel operates independently with identical electrical behavior and shares a single VCC and GND rail.
The Ioff circuitry actively disables outputs during power-down, blocking current backflow and supporting hot-plug operation. Input tolerance up to 5.5 V allows interfacing with higher-voltage logic while powered from as low as 1.65 V, making it suitable for mixed-supply systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports dual-supply domain bridging and battery-powered operation down to 1.65 V |
| Max tpd | 5.4 ns at 3.3 V - enables high-speed signal conditioning in timing-critical interfaces like USB or display control |
| Output Drive | ±24 mA at 3.3 V - sufficient to directly drive multiple CMOS loads or small LEDs without external buffers |
| Ioff Current | ±10 μA max - ensures safe isolation during partial power-down, preventing bus contention in modular systems |
| Input Threshold Hysteresis | 0.56 V to 1.11 V - rejects noise spikes up to ~1 V on slow-rising signals such as mechanical switch debouncing |
| VI Max | 5.5 V - allows 5-V-tolerant inputs even when VCC = 1.65 V, simplifying level translation in mixed-voltage designs |
| ICC Max | 10 μA - ultra-low static power ideal for always-on subsystems in portable electronics |
Pinout & Package
SN74LVC3G17DCTRE4 uses an 8-pin SSOP (DCT) package measuring 2.95 mm × 2.80 mm, optimized for space-constrained PCB layouts while maintaining hand-solderability and standard reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Input 1 | Noninverting Schmitt-trigger input for Channel 1; accepts 0–5.5 V regardless of VCC |
| 1Y | Output 1 | Buffered noninverting output for Channel 1; drives ±24 mA at 3.3 V |
| 2A | Input 2 | Noninverting Schmitt-trigger input for Channel 2; electrically identical to 1A |
| 2Y | Output 2 | Buffered noninverting output for Channel 2; fully independent of other channels |
| 3A | Input 3 | Noninverting Schmitt-trigger input for Channel 3; supports same VI range and thresholds |
| 3Y | Output 3 | Buffered noninverting output for Channel 3; shares VCC/GND but no internal coupling |
| GND | Ground | Reference return path for all I/O and internal circuitry; must be low-impedance |
| VCC | Power Supply | Single supply rail (1.65–5.5 V); requires local 0.1-μF bypass capacitor per TI layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Provides hysteresis (ΔVT ≥ 0.56 V) to eliminate chatter on slow or noisy signals like pushbutton inputs or sensor outputs |
| Ioff partial-power-down | Disables outputs and blocks back-current when VCC = 0 V, enabling safe live insertion into powered backplanes |
| 5.5-V tolerant inputs | Accepts logic-high signals up to 5.5 V independent of VCC setting-eliminates need for external level shifters |
| NanoFree™ packaging | SSOP (DCT) footprint leverages die-as-package concept for minimal board area without sacrificing thermal or solder reliability |
| ESD robustness | 2000-V HBM, 1000-V CDM - exceeds JEDEC standards for handling in automated assembly and field service |
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 |
|---|---|---|---|
| SN74LVC1G17DCKR | Single-channel version in SC70-5 package; identical VCC range, tpd, and Ioff but only one buffer | Used where only one Schmitt input is needed; saves board area but requires three devices for triple functionality | Select when minimizing component count outweighs PCB area savings from integrated triple function |
| MC74VHC1GT50DTT1G | Single-channel, 2–5.5 V operation, 7.5 ns tpd at 3.3 V, no Ioff, 5-V tolerant inputs | Lacks partial-power-down protection; not suitable for hot-swap or mixed-power domains requiring Ioff | Choose only for cost-sensitive, fixed-supply applications where live insertion is not required |
Compared with SN74LVC3G17DCTRE4, SN74LVC1G17DCKR offers identical per-channel performance in smaller form factor but increases BOM count and routing complexity for triple-buffer needs; MC74VHC1GT50DTT1G trades off Ioff and speed for lower unit cost in static, single-rail systems.

FAQ
What is the maximum propagation delay of the SN74LVC3G17DCTRE4 at 3.3 V?
The maximum propagation delay (tpd) of the SN74LVC3G17DCTRE4 is 5.4 ns when operating at VCC = 3.3 V with CL = 30 pF or 50 pF, as specified in the Switching Characteristics table of the official datasheet. This value applies across the full operating temperature range of –40°C to 125°C and ensures predictable timing in high-speed digital interfaces. The SN74LVC3G17DCTRE4 maintains this performance while supporting Schmitt-trigger hysteresis and Ioff functionality.
Does the SN74LVC3G17DCTRE4 support partial power-down operation?
Yes, the SN74LVC3G17DCTRE4 fully supports partial power-down operation via its Ioff feature. When VCC is at 0 V, the Ioff circuitry disables all three outputs and limits leakage current to ±10 μA, preventing damaging current backflow from live system buses. This capability is explicitly validated per JESD 78 Class II latch-up testing and enables safe live insertion in modular systems. The SN74LVC3G17DCTRE4 implements this without external components or configuration.
Can the SN74LVC3G17DCTRE4 accept 5-V input signals while powered from 1.8 V?
Yes, the SN74LVC3G17DCTRE4 accepts input voltages up to 5.5 V regardless of VCC level-including when powered from 1.8 V-due to its overvoltage-tolerant input structure. This eliminates the need for external level-shifting circuitry when interfacing with legacy 5-V logic or sensors. All three inputs (1A, 2A, 3A) share this capability, and the SN74LVC3G17DCTRE4 maintains full Schmitt-trigger hysteresis and output drive performance under these conditions.
What package type and dimensions does the SN74LVC3G17DCTRE4 use?
The SN74LVC3G17DCTRE4 uses an 8-pin SSOP (Shrink Small Outline Package) designated DCT, with nominal body dimensions of 2.95 mm × 2.80 mm and 0.65-mm lead pitch. It is RoHS-compliant, features NiPdAu lead finish, and carries a moisture sensitivity level (MSL) rating of Level-1 at 260°C peak reflow. This package balances compactness, manufacturability, and thermal performance-distinct from the VSSOP (DCU) and DSBGA (YZP) variants of the same device family. The SN74LVC3G17DCTRE4 marking is "C17".
How does the Schmitt-trigger action of the SN74LVC3G17DCTRE4 improve noise immunity?
The SN74LVC3G17DCTRE4 improves noise immunity through asymmetric input thresholds: VT+ (positive-going) ranges from 0.79 V to 3.33 V and VT– (negative-going) from 0.39 V to 2.29 V, yielding hysteresis (ΔVT) of 0.56 V to 1.11 V depending on VCC. This gap prevents multiple output transitions when input signals cross the threshold slowly or with superimposed noise-critical for debouncing mechanical switches or cleaning up noisy sensor outputs. Unlike standard buffers, the SN74LVC3G17DCTRE4 guarantees monotonic response without external RC networks.
