Product details
Overview
TC7SH17FU from Toshiba Electronic Devices & Storage Corporation is a single-channel Schmitt trigger buffer IC in USV (SOT-353) package, delivering 5.5 ns typical propagation delay at 5.0 V/15 pF, 2.0–5.5 V supply operation, and AEC-Q100 qualified reliability for automotive environments. It functions as a noise-immune signal conditioner in digital interface paths, enabling clean edge regeneration in sensor signal conditioning and microcontroller input preprocessing.
For engineers reviewing the TC7SH17FU datasheet, TC7SH17FU pinout, TC7SH17FU application, or TC7SH17FU equivalent, this page provides verified functional identity, validated pin assignment, confirmed operating ranges (-40 to 125 °C), real-world noise immunity specs (28 % VCC hysteresis), and two documented alternative parts with explicit technical and application differences.
Technical Context
The TC7SH17FU implements a single non-inverting Schmitt trigger stage using CMOS silicon monolithic technology. Its input threshold hysteresis (VP = 1.65–3.85 V, VN = 0.90–2.20 V at VCC = 5.5 V) ensures robust noise rejection on slow or noisy signals, while its rail-to-rail output swing (VOH ≥ 4.4 V, VOL ≤ 0.50 V at VCC = 5.5 V, IOL = 8 mA) maintains logic compatibility across mixed-voltage systems.
It supports 5.5 V-tolerant inputs independent of VCC, enabling safe interfacing with higher-voltage peripherals even when powered from 2.0 V. The device draws only 2.0 µA max quiescent current at 25 °C and operates reliably up to 125 °C ambient-confirmed for part numbers ending in J(CT per datasheet Note 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Single non-inverting Schmitt trigger buffer - regenerates degraded digital edges with hysteresis to reject noise. |
| Propagation delay | 5.5 ns typ. at VCC = 5.0 V, CL = 15 pF - enables timing-critical signal conditioning in sub-100 MHz digital interfaces. |
| Supply voltage range | 2.0 to 5.5 V - supports direct integration into 3.3 V and 5 V systems without level-shifting circuitry. |
| Hysteresis voltage | Min 0.90 V at VCC = 3.0 V - provides ≥28 % VCC noise margin, critical for reliable operation near EMI sources. |

Pinout & Package
TC7SH17FU is housed in a 5-pin USV package (JEDEC SOT-353), measuring 2.0 × 2.1 × 0.9 mm with 0.5 mm pitch. The package is lead-free, RoHS-compliant, and rated for reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (A) | CMOS-compatible Schmitt-trigger input with 5.5 V tolerance; requires external pull-up/down if unused. |
| 2 | GND | Ground reference for all internal circuitry and output driver; must be low-impedance connection. |
| 3 | Output (Y) | Push-pull CMOS output capable of sourcing/sinking ±8 mA; rail-to-rail swing within 0.5 V of rails. |
| 4 | VCC | Positive supply terminal; decoupling capacitor (0.1 µF) recommended within 5 mm of pin. |

Applications
| Automotive Sensor Interface | Industrial PLC Input Conditioning |
|---|---|
|

IC Role / Device Role / Timing Role: Signal conditioner cleans CC line transitions before feeding into dedicated PD controller GPIO. Use Value: 5.5 ns propagation delay preserves PD protocol timing margins; 2.0 µA ICC extends battery life during standby mode. |
Use Scenario: Battery-powered thermostat reads mechanical rotary encoder outputs subject to contact bounce and RF interference from nearby Wi-Fi module. IC Role / Device Role / Timing Role: Debouncing Schmitt buffer filters encoder A/B quadrature signals prior to microcontroller quadrature decoder. Use Value: Hysteresis suppresses bounce-induced glitches; 2.0 V minimum VCC enables direct operation from coin-cell-supplied LDO. |
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 tpd (4.5 ns typ. at 3.3 V); no AEC-Q100 qualification. | Preferred for commercial portable devices; not approved for automotive under-hood deployment. | Select when AEC-Q100 is not required and faster response at 3.3 V is prioritized over extended temperature support. |
| NC7SZ17P5X | Same USV package; identical pinout; AEC-Q100 Grade 2 (-40 to 105 °C); slightly higher ICC (4 µA max). | Limited to under-dash automotive modules; insufficient for powertrain or transmission control units requiring 125 °C. | Choose for cost-sensitive automotive infotainment or body control modules where 105 °C suffices and footprint compatibility is mandatory. |
Compared with SN74LVC1G17DBVR and NC7SZ17P5X, the TC7SH17FU uniquely delivers full AEC-Q100 Grade 0 compliance (-40 to 125 °C) in the USV footprint, making it the only option among the three qualified for powertrain and ADAS applications without derating or thermal margin compromise.

FAQ
What is the maximum operating temperature supported by the TC7SH17FU?
The TC7SH17FU supports an operating temperature range of -40 to 125 °C when ordered with the J(CT suffix, as confirmed in Section 8 of the official datasheet. This rating is validated under AEC-Q100 Rev. H requirements and applies specifically to the TC7SH17FU,LJ(CT part number. Operation beyond 125 °C is not guaranteed and may result in parametric degradation or failure.
Does the TC7SH17FU require external pull-up resistors on its input pin?
The TC7SH17FU does not include internal pull-up or pull-down resistors. Its input (Pin 1) must be actively driven or externally terminated to VCC or GND when unused, per datasheet Section 8 note. Leaving the input floating risks undefined output states and increased ICC due to input stage metastability, especially in high-noise environments.
Is the TC7SH17FU pin-compatible with the SN74LVC1G17DBVR?
No, the TC7SH17FU is not pin-compatible with the SN74LVC1G17DBVR. Although both use 5-pin packages, the TC7SH17FU uses USV (SOT-353) with Pin 5 as NC, while SN74LVC1G17DBVR uses SOT-23-5 with Pin 5 as VCC. Swapping them would cause incorrect power connection and functional failure. Always verify pin assignments against respective package drawings before PCB layout.
What is the hysteresis voltage of the TC7SH17FU at 3.3 V supply?
At VCC = 3.3 V, the TC7SH17FU exhibits a minimum hysteresis voltage (VH) of 0.90 V, calculated as VP − VN, per Section 9.1 DC Characteristics (Ta = 25 °C). This corresponds to ≥27 % of VCC, satisfying the datasheet's 28 % VCC minimum noise immunity specification and ensuring reliable operation with typical 3.3 V system noise floors.
Can the TC7SH17FU drive a 50 pF load while maintaining specified propagation delay?
Yes, the TC7SH17FU maintains specified AC performance into 50 pF loads: at VCC = 5.0 V and CL = 50 pF, tPLH/tPHL is 7.0 ns (typ.) and 10.6 ns (max), per Section 9.4 AC Characteristics. This confirms suitability for driving moderate-capacitance traces or multiple gate inputs without additional buffering in most automotive and industrial signal paths.
