Product details
Overview
TC7SZ17FU,LJ(CT from Toshiba Electronic Devices & Storage Corporation is a single-channel Schmitt trigger buffer IC in USV (SOT-353) package, operating from 1.65 V to 5.5 V supply, delivering ±24 mA output drive at 3.0 V, with 3.7 ns typical propagation delay at 5.0 V/50 pF, and AEC-Q100 qualified for automotive applications.
For engineers reviewing the TC7SZ17FU,LJ(CT datasheet, TC7SZ17FU,LJ(CT pinout, TC7SZ17FU,LJ(CT application, or TC7SZ17FU,LJ(CT equivalent, this device serves as a noise-immune signal conditioner for low-voltage digital interfaces in automotive control units, industrial sensors, and battery-powered IoT edge nodes requiring robust input hysteresis and 5.5 V-tolerant inputs.
Technical Context
The TC7SZ17FU,LJ(CT implements a single non-inverting Schmitt trigger buffer with hysteresis voltage of 0.48 V (typ.) at 3.0 V, enabling reliable signal restoration in noisy environments. Its input threshold voltages are VP = 1.75 V and VN = 1.27 V (typ., VCC = 3.0 V), yielding defined switching margins independent of noise amplitude.
It supports rail-to-rail output swing, features 5.5 V-tolerant inputs and power-down protection on outputs, and maintains stable operation across -40 °C to +125 °C - confirmed for devices with ordering code ending in J(CT per datasheet Note 2 and Section 8.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Single non-inverting Schmitt trigger buffer - provides noise immunity via hysteresis for unreliable input signals. |
| Supply Voltage Range | 1.65 V to 5.5 V - enables interoperability across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| Propagation Delay | 3.7 ns (typ.) at VCC = 5.0 V, CL = 50 pF - supports high-speed signal conditioning in timing-critical paths. |
| Output Drive | ±24 mA (min.) at VCC = 3.0 V - directly drives moderate capacitive loads or multiple CMOS inputs without buffering. |
| Input Hysteresis | 0.48 V (typ.) at VCC = 3.0 V - rejects noise spikes up to ~500 mV peak-to-peak without false triggering. |
| Operating Temperature | -40 °C to +125 °C - validated for under-hood automotive ECUs and industrial motor control modules. |
| Input Tolerance | 5.5 V tolerant - allows interfacing with higher-voltage peripherals while powered from lower VCC. |
Pinout & Package
TC7SZ17FU,LJ(CT is housed in a 5-pin USV package (JEDEC SOT-353), measuring 2.0 × 1.25 × 0.9 mm, with 0.65 mm lead pitch and gull-wing leads. The package is RoHS-compliant and optimized for space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (A) | CMOS-compatible Schmitt-trigger input with 5.5 V tolerance; accepts logic levels independent of VCC. |
| 2 | GND | Ground reference for all internal circuitry and output return path. |
| 3 | Output (Y) | Push-pull CMOS output with ±24 mA drive capability; includes power-down protection when VCC = 0 V. |
| 4 | VCC | Positive supply rail (1.65–5.5 V); powers internal logic and output stage. |
| 5 | N/C | No-connect terminal - left unconnected; electrically isolated and not bonded internally. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified (Rev. H) | Validated for automotive-grade reliability including temperature cycling, HTOL, and ESD (HBM ≥2 kV). |
| Wide VCC range (1.65–5.5 V) | Eliminates need for external voltage translators in mixed-supply systems such as ADAS sensor hubs. |
| 5.5 V-tolerant inputs | Permits direct connection to 5 V microcontrollers or legacy peripherals without clamping diodes or resistors. |
| Power-down protection | Outputs enter high-impedance state with <0.1 µA leakage when VCC = 0 V - prevents back-driving during hot-swap or power sequencing. |
| High noise immunity | Hysteresis of 0.48 V (typ.) ensures clean transitions even with >300 mV of superimposed noise on input traces. |
Applications
| Automotive Body Control Module | Industrial Sensor Interface |
|---|---|
Use Scenario: Signal conditioning for mechanical switch inputs (e.g., door latch, hood open) exposed to EMI in vehicle wiring harnesses. IC Role / Device Role / Timing Role: Schmitt buffer restores clean digital edges from slow, bouncing, or noisy switch signals before MCU GPIO sampling. Use Value: Prevents false wake-up events and contact chatter misreads, improving system reliability without firmware debouncing overhead. |
Use Scenario: Interfacing analog-output pressure/temperature sensors to SAR ADCs in PLC I/O modules. IC Role / Device Role / Timing Role: Converts slow-rising sensor enable signals into sharp-edged clock or CS pulses with noise margin.

| Portable Medical Device | Smart Home Motion Detector |
Use Scenario: Debouncing tactile buttons on battery-powered glucose meters or pulse oximeters. IC Role / Device Role / Timing Role: Single-gate Schmitt buffer cleans button actuation signals prior to ultra-low-power MCU wake-up interrupt. Use Value: Reduces false triggers from mechanical bounce while consuming only 0.22 µA (typ.) quiescent current at 3.0 V. |
Use Scenario: Conditioning PIR sensor output signals in wireless occupancy sensors subject to RF interference. IC Role / Device Role / Timing Role: Provides hysteresis-based signal regeneration before feeding into low-power sub-GHz transceiver wake logic. Use Value: Increases detection confidence by rejecting ambient EMI-induced transients that would otherwise cause spurious alerts. |
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 SOT-353 package, 1.65–5.5 V operation, but rated only to +85 °C (not AEC-Q100 qualified); tPD = 4.5 ns (typ.) at 3.3 V. | Lacks automotive qualification and extended temperature support; suitable for commercial-grade consumer or industrial use only. | Select SN74LVC1G17DBVR where AEC-Q100 compliance and 125 °C operation are not required - lower cost, same footprint. |
| NC7SZ17P5X | USV package, AEC-Q100 compliant, but max operating temperature is +105 °C (not +125 °C); VOH = 2.7 V (min.) at VCC = 3.3 V vs. TC7SZ17FU,LJ(CT's 2.9 V (min.). | Marginally lower output voltage drive and thermal rating - may limit interface margin in high-temperature CAN/LIN subsystems. | Choose NC7SZ17P5X if full 125 °C operation is unnecessary and existing design uses ON Semi's qualification documentation flow. |
Compared with SN74LVC1G17DBVR and NC7SZ17P5X, the TC7SZ17FU,LJ(CT uniquely combines AEC-Q100 Rev. H certification, guaranteed -40 °C to +125 °C operation, and 5.5 V-tolerant inputs - making it the only option among the three qualified for under-hood automotive signal conditioning where thermal and reliability margins are non-negotiable.

FAQ
What is the maximum operating temperature for TC7SZ17FU,LJ(CT?
The TC7SZ17FU,LJ(CT is specified for operation from -40 °C to +125 °C, as confirmed in Section 8 of the official Toshiba datasheet (Rev. 3.0.B) for devices with ordering code ending in J(CT. This rating is validated per AEC-Q100 Rev. H requirements and applies across the full 1.65–5.5 V supply range.
Does TC7SZ17FU,LJ(CT support 1.8 V logic interfaces?
Yes, TC7SZ17FU,LJ(CT fully supports 1.8 V operation: its minimum supply voltage is 1.65 V, and DC characteristics (e.g., VOH ≥ 1.55 V at IOH = –4 mA) and AC performance (tPD = 9.1 ns typ. at VCC = 1.8 V) are explicitly characterized down to 1.8 V ± 0.15 V in Section 9.4 of the datasheet.
Is TC7SZ17FU,LJ(CT pin-compatible with other SOT-353 Schmitt buffers?
TC7SZ17FU,LJ(CT uses standard SOT-353 pinout (pin 1 = A, pin 2 = GND, pin 3 = Y, pin 4 = VCC, pin 5 = N/C), matching industry-standard footprints like SN74LVC1G17DBVR and NC7SZ17P5X. However, pin compatibility alone does not guarantee functional equivalence - verify hysteresis, drive strength, and temperature rating for your application.
What is the input hysteresis voltage of TC7SZ17FU,LJ(CT at 3.3 V supply?
At VCC = 3.3 V, the TC7SZ17FU,LJ(CT exhibits a typical hysteresis voltage (VH) of 0.77 V, calculated as VP – VN = 2.0 V – 1.23 V (typ. values from Section 9.1 DC Characteristics). This provides robust noise rejection for signals with up to ~700 mV peak-to-peak interference.
Can TC7SZ17FU,LJ(CT inputs be driven by 5 V logic while VCC = 3.3 V?
Yes - TC7SZ17FU,LJ(CT features 5.5 V-tolerant inputs (Section 2, Feature #6), meaning it safely accepts 0–5.5 V input signals regardless of VCC level (1.65–5.5 V). This allows direct interfacing with 5 V microcontrollers or sensors without external level-shifting components.
