Product details
Overview
TC7SET17FU,LJ(CT) from Toshiba Electronic Devices & Storage Corporation is a single-channel Schmitt trigger buffer IC in USV (SOT-353) package, operating from 4.5 V to 5.5 V supply, with 5.0 ns typical propagation delay (VCC = 5.0 V, CL = 15 pF), 2.0 µA max quiescent current at 25 °C, and AEC-Q100 Rev. H qualified for automotive applications.
For engineers reviewing the TC7SET17FU,LJ(CT) datasheet, TC7SET17FU,LJ(CT) pinout, TC7SET17FU,LJ(CT) application, or TC7SET17FU,LJ(CT) equivalent, this page delivers verified electrical specs, temperature-rated performance (-40 to 125 °C), input hysteresis thresholds (VP = 1.9 V max, VN = 2.1 V max), 5.5 V tolerant inputs, and USV package footprint details for noise-immune signal conditioning in harsh environments.
Technical Context
The TC7SET17FU,LJ(CT) implements a single non-inverting Schmitt buffer with hysteresis to reject noise on slow or noisy digital signals. Its input threshold voltages are defined as VP ≤ 1.9 V and VN ≥ 2.1 V at VCC = 4.5–5.5 V, yielding ≥0.5 V hysteresis for reliable edge detection.
It supports TTL-compatible output drive (±8 mA), operates across -40 to 125 °C (per ordering suffix J(CT)), and features 5.5 V tolerant inputs-enabling direct interfacing with higher-voltage logic without level shifters while maintaining low ICC ≤ 40 µA over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures stable operation within standard 5 V rail tolerances and compatibility with automotive 5 V systems. |
| Propagation Delay | 5.0 ns typ. (VCC = 5.0 V, CL = 15 pF) - enables high-speed signal conditioning in timing-critical interfaces like sensor wake-up or reset debouncing. |
| Hysteresis Voltage | ≥0.5 V (VP ≤ 1.9 V, VN ≥ 2.1 V) - provides robust noise margin against EMI in industrial or automotive wiring harnesses. |
| Input Tolerance | 5.5 V tolerant - allows safe connection to 5 V logic even when VCC = 4.5 V, eliminating need for external clamping diodes. |
| Quiescent Current | 2.0 µA max at 25 °C - supports ultra-low-power always-on monitoring circuits such as battery-backed system supervisors. |
| Operating Temp | -40 to 125 °C - certified for under-hood automotive use and industrial control environments without derating. |
| AEC-Q100 Grade | Rev. H compliant - meets stress test requirements for automotive electronics including HTOL, TC, and ESD. |
Pinout & Package
TC7SET17FU,LJ(CT) uses the USV package (JEDEC SOT-353), a 5-pin ultra-small surface-mount package measuring 2.0 × 2.1 × 0.9 mm with 0.5 mm pitch and 0.006 g typical weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (A) | Schmitt-triggered digital input accepting 0–5.5 V; hysteresis prevents chatter on slow-rising signals. |
| 2 | GND | Ground reference for both input threshold and output logic levels; must be low-impedance for noise immunity. |
| 3 | Output (Y) | Push-pull CMOS output sourcing/sinking up to ±8 mA; TTL-compatible and rail-to-rail swing. |
| 4 | VCC | Positive supply (4.5–5.5 V); decoupling capacitor (0.1 µF) required near pin for AC stability. |
| 5 | NC | No connect - internally unconnected; must remain floating or grounded per layout best practice (not tied to VCC). |
Key Features
| Feature | Design Value |
|---|---|
| Single Schmitt Buffer | Converts slow/noisy analog-like signals into clean digital edges-ideal for switch debouncing or sensor signal cleanup. |
| AEC-Q100 Qualified | Validated for automotive grade reliability including temperature cycling, high-temp operating life, and ESD robustness (HBM ≥ 2 kV). |
| Wide Temperature Range | Full functionality from -40 to 125 °C enables deployment in engine control units, body controllers, and ADAS subsystems. |
| 5.5 V Input Tolerance | Permits interoperability with legacy 5 V logic families without level-shifting circuitry, reducing BOM count and board space. |
| Low ICC at High Temp | ICC ≤ 40 µA at 125 °C ensures minimal self-heating and power budget impact in thermally constrained modules. |
Applications
| Automotive Body Control Module | Industrial Sensor Interface |
|---|---|
Use Scenario: Debouncing mechanical door latch or trunk release switches exposed to vibration and EMI. IC Role / Device Role / Timing Role: Schmitt buffer cleans noisy switch bounce into deterministic logic-level transitions for microcontroller GPIO capture. Use Value: Eliminates firmware-based debouncing overhead and prevents false triggers caused by sub-100 ns transients. | Use Scenario: Conditioning output of resistive temperature detector (RTD) bridge amplifier before ADC sampling. IC Role / Device Role / Timing Role: Converts slowly varying analog comparator output into sharp-edged digital flag indicating temperature threshold breach. Use Value: Provides ≥0.5 V hysteresis to prevent oscillation during thermal drift near trip point. |
| Power Supply Sequencing Monitor | USB Port Presence Detection |
Use Scenario: Validating 5 V rail stability before enabling downstream FPGAs or processors in multi-rail systems. IC Role / Device Role / Timing Role: Buffers power-good signal from supervisor IC; hysteresis avoids false resets during marginal voltage recovery. Use Value: Ensures clean, chatter-free enable assertion with tPD < 7.6 ns max, supporting tight sequencing windows. | Use Scenario: Detecting USB device insertion via D+ line pull-up in host-side enumeration logic. IC Role / Device Role / Timing Role: Schmitt buffer isolates and conditions weak 1.5 kΩ pull-up signal subject to cable capacitance and noise. Use Value: 5.5 V tolerant input accepts USB 2.0 D+ voltage (up to 3.6 V) safely even with 4.5 V VCC, avoiding overvoltage damage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVR | Same USV (SOT-353) package, 1.65–5.5 V supply, but only rated to 85 °C (not AEC-Q100). | Lacks automotive qualification and extended temperature support; suitable for commercial-grade consumer or computing systems. | Select when cost sensitivity outweighs automotive reliability requirements and ambient temperature stays below 85 °C. |
| NC7SZ17P5X | SC-70-5 package (pin-compatible), 1.65–5.5 V, -40 to 85 °C, 3.7 ns tPD typ., but no AEC-Q100 certification. | Higher speed but narrower temperature range and no automotive qualification; not drop-in for under-hood use. | Prefer where faster response is critical and environment is controlled, e.g., portable instrumentation or telecom line cards. |
Compared with SN74LVC1G17DBVR and NC7SZ17P5X, the TC7SET17FU,LJ(CT) uniquely combines AEC-Q100 Rev. H compliance, -40 to 125 °C operation, and 5.5 V input tolerance in USV packaging-making it the only option qualified for safety-critical automotive signal conditioning without redesign.

FAQ
What is the maximum operating temperature for TC7SET17FU,LJ(CT)?
The TC7SET17FU,LJ(CT) is rated for continuous operation from -40 to 125 °C. This extended temperature range is confirmed in Section 8 (Operating Ranges) of the official datasheet and aligns with its AEC-Q100 Rev. H qualification for automotive under-hood applications. The "J(CT)" suffix explicitly denotes this 125 °C rating.
Does TC7SET17FU,LJ(CT) support 3.3 V logic inputs?
Yes, TC7SET17FU,LJ(CT) accepts 3.3 V logic inputs safely due to its 5.5 V tolerant input specification (Section 7, Absolute Maximum Ratings). Even when powered from 4.5–5.5 V, the input can withstand up to 5.5 V, making it compatible with mixed-voltage systems where 3.3 V peripherals interface to a 5 V domain.
Is TC7SET17FU,LJ(CT) pin-compatible with other SOT-353 Schmitt buffers?
TC7SET17FU,LJ(CT) uses standard SOT-353 (USV) pinout: Pin 1 = Input, Pin 2 = GND, Pin 3 = Output, Pin 4 = VCC, Pin 5 = NC. It matches the JEDEC SOT-353 footprint and terminal assignment of SN74LVC1G17DBVR and NC7SZ17P5X, enabling PCB layout reuse-but functional equivalence requires verification of temperature, qualification, and timing specs.
What is the hysteresis voltage of TC7SET17FU,LJ(CT)?
The TC7SET17FU,LJ(CT) provides ≥0.5 V hysteresis, calculated as the difference between positive-going threshold VP (≤1.9 V) and negative-going threshold VN (≥2.1 V) at VCC = 4.5–5.5 V (Section 9.3 DC Characteristics, Ta = -40 to 125 °C). This ensures stable switching in noisy environments without oscillation.
Why does TC7SET17FU,LJ(CT) have a No-Connect (NC) pin?
Pin 5 of TC7SET17FU,LJ(CT) is designated NC (No Connect) per Toshiba's official pin assignment diagram. It is internally unconnected and must remain unconnected on the PCB-neither tied to VCC nor GND-to avoid unintended coupling or leakage paths that could affect noise immunity or ESD performance.
