Product details
Overview
TC7SET17F,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, delivering 5.0 ns typical propagation delay at 5.0 V/15 pF load, with ±25 mA output drive capability and AEC-Q100 Rev. H qualification for automotive applications.
For engineers reviewing the TC7SET17F,LJ(CT) datasheet, TC7SET17F,LJ(CT) pinout, TC7SET17F,LJ(CT) application, or TC7SET17F,LJ(CT) equivalent, this device is selected for noise-immune signal conditioning in automotive body control modules, industrial sensor interfaces, and legacy TTL-compatible logic translation where wide temperature range (-40 to +85 °C) and 5.5 V-tolerant inputs are required.
Technical Context
The TC7SET17F,LJ(CT) implements a single non-inverting Schmitt trigger input stage followed by a push-pull CMOS output stage. Its hysteresis voltage is specified at ≥0.5 V (min), with positive and negative thresholds of 1.9 V (max) and 0.6 V (min), respectively, enabling robust noise rejection on slow or noisy digital signals.
It operates within a strict 4.5–5.5 V VCC range and supports input voltages up to 5.5 V independent of supply - critical for interfacing with higher-voltage legacy systems. Quiescent current is limited to 2.0 µA (max) at 25 °C, supporting low-power always-on monitoring functions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Single non-inverting Schmitt trigger buffer - converts slow/noisy signals into clean CMOS/TTL-compatible logic edges. |
| Supply Voltage | 4.5 V to 5.5 V - requires stable 5 V rail; not operable below 4.5 V or above 5.5 V. |
| Propagation Delay | 5.0 ns (typ.) at VCC = 5.0 V, CL = 15 pF - enables timing-critical signal conditioning in sub-10 ns logic paths. |
| Hysteresis Voltage | ≥0.5 V (min) - provides ≥500 mV noise margin against EMI or crosstalk on input lines. |
| Input Voltage Range | -0.5 V to 5.5 V - allows direct connection to 5 V TTL outputs without level-shifting circuitry. |
| Output Drive | ±25 mA (DC), 8 mA (switching) - sufficient to drive multiple 74HC inputs or small LED indicators. |
| Operating Temperature | -40 °C to +85 °C - qualified for under-hood automotive and industrial control environments. |
Pinout & Package
TC7SET17F,LJ(CT) is housed in a 5-pin USV package (JEDEC SOT-353), measuring 2.0 × 2.1 × 0.9 mm, with 0.5 mm lead pitch and gull-wing surface-mount terminals. The package is RoHS-compliant and optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (A) | Schmitt-triggered input; accepts 5.5 V-tolerant logic levels regardless of VCC. |
| 2 | GND | Ground reference for both input threshold and output stage; must be low-impedance. |
| 3 | Output (Y) | CMOS push-pull output; drives high/low actively; no pull-up required. |
| 4 | VCC | Positive supply (4.5–5.5 V); bypass capacitor (0.1 µF) recommended near pin. |
| 5 | N/C | No internal connection; left unconnected per datasheet - not usable as spare terminal. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Rev. H qualified | Validated for automotive use including temperature cycling, HTOL, and ESD testing - suitable for body electronics without additional qualification. |
| 5.5 V tolerant inputs | Enables direct interface with 5 V TTL or older microcontroller GPIOs without external resistors or level shifters. |
| Low ICC (2.0 µA max) | Supports always-on wake-up detection circuits in battery-backed systems with minimal standby current impact. |
| Hysteresis ≥0.5 V | Rejects noise spikes ≤500 mV amplitude - essential for switch debouncing and analog-sensor digitization. |
| TTL-output compatible | Drives standard 74LS/74HC loads directly; VOH ≥4.4 V and VOL ≤0.4 V at 8 mA ensure reliable logic-level recognition. |
Applications
| Automotive Body Control Unit | Industrial Sensor Interface |
|---|---|
|
Use Scenario: Conditioning mechanical switch inputs (door latch, trunk release) exposed to EMI and contact bounce in vehicle cabin wiring harnesses. IC Role / Device Role / Timing Role: Schmitt buffer providing noise-immune signal conditioning and edge sharpening before MCU GPIO sampling. Use Value: Eliminates need for external RC debounce networks and software debouncing routines, reducing BOM count and firmware complexity. |
Use Scenario: Digitizing analog output from thermistors or potentiometers in PLC I/O modules operating in electrically noisy factory environments. IC Role / Device Role / Timing Role: Threshold comparator with hysteresis converting analog voltage thresholds into clean digital status flags. Use Value: Provides deterministic switching points (VP/VN) and ≥0.5 V hysteresis to prevent chatter during slow thermal transitions. |
| Legacy System Logic Translation | Microcontroller GPIO Protection |
|
Use Scenario: Interfacing 5 V TTL outputs from legacy industrial controllers with 5 V CMOS microcontrollers requiring clean input transitions. IC Role / Device Role / Timing Role: Level-adapting buffer ensuring VIH/VIL compatibility while adding noise immunity. Use Value: 5.5 V-tolerant input accepts TTL VOH (2.4 V min) with margin; output VOH ≥4.4 V meets 74HC VIH requirement reliably. |
Use Scenario: Protecting sensitive MCU GPIO pins from overvoltage transients and ESD events in field-deployed equipment. IC Role / Device Role / Timing Role: Input buffer isolating MCU from external wiring; clamps input to safe range via internal diodes. Use Value: Absolute max input rating of -0.5 V to 7.0 V and built-in input protection diodes reduce need for external TVS components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVR | Wider VCC range (1.65–5.5 V); lower ICC (10 µA typ.); no AEC-Q100 qualification. | Preferred for portable/battery-powered 3.3 V systems; unsuitable for automotive AEC-Q100-requiring designs. | Select SN74LVC1G17DBVR only when operating below 4.5 V or when AEC-Q100 compliance is not mandated. |
| NC7SZ17P5X | Same USV package; 1.65–5.5 V operation; 3.5 ns tPD (typ.); no AEC-Q100; higher ICC (10 µA max). | Better speed for 3.3 V logic domains; lacks automotive qualification and 5.5 V input tolerance. | Choose NC7SZ17P5X for cost-sensitive consumer applications needing faster response but not automotive reliability. |
Compared with SN74LVC1G17DBVR and NC7SZ17P5X, the TC7SET17F,LJ(CT) trades wider supply flexibility for guaranteed AEC-Q100 compliance, 5.5 V input tolerance, and tighter -40 to +85 °C performance - making it the sole choice for automotive body electronics where qualification and interface robustness are mandatory.

FAQ
What is the operating temperature range for TC7SET17F,LJ(CT)?
The TC7SET17F,LJ(CT) is rated for operation from -40 °C to +85 °C. This range is explicitly defined in the datasheet for parts ending in "J(CT" - confirmed in Section 8 (Operating Ranges, Note 1). It does not support the extended -40 to +125 °C range offered by the FU variant.
Is TC7SET17F,LJ(CT) AEC-Q100 qualified?
Yes, the TC7SET17F,LJ(CT) is compliant with AEC-Q100 Rev. H requirements, as stated in Section 2. Features (Item 1) of the official Toshiba datasheet. This qualification covers stress tests including temperature cycling, high-temperature operating life, and ESD robustness required for automotive electronics.
What is the maximum input voltage allowed on TC7SET17F,LJ(CT)?
The absolute maximum input voltage for TC7SET17F,LJ(CT) is -0.5 V to 7.0 V (Section 7, Absolute Maximum Ratings), but the functional input voltage range is -0.5 V to 5.5 V (Section 8, Operating Ranges). The 5.5 V tolerance enables safe interfacing with 5 V TTL outputs without external clamping.
Does TC7SET17F,LJ(CT) have a pull-up or pull-down on the input?
No, the TC7SET17F,LJ(CT) has no internal pull-up or pull-down resistor on the input pin. Unused inputs must be externally tied to either VCC or GND per Section 8 (Operating Ranges, Note) to prevent floating states and undefined output behavior.
What package type is used for TC7SET17F,LJ(CT)?
The TC7SET17F,LJ(CT) uses the USV package - a 5-pin JEDEC-standard SOT-353 footprint (2.0 × 2.1 × 0.9 mm, 0.5 mm pitch), as confirmed in the "Package Dimensions" section and Section 3 (Packaging) of the Toshiba datasheet.
