Product details
Overview
TC7SET17FTE85LF from Toshiba Electronic Devices & Storage Corporation is a single-channel Schmitt trigger buffer IC designed for noise-immune signal conditioning in automotive and industrial digital interfaces. It operates from 4.5 V to 5.5 V, delivers 5.0 ns typical propagation delay at 5 V/15 pF, supports -40°C to +125°C ambient operation, and features 5.5 V tolerant inputs-enabling robust interfacing with mixed-voltage systems in engine control units and sensor signal chains.
For engineers reviewing the TC7SET17FTE85LF datasheet, TC7SET17FTE85LF pinout, TC7SET17FTE85LF application, or TC7SET17FTE85LF equivalent, key selection criteria include AEC-Q100 Rev. H qualification, hysteresis voltage ≥0.5 V (min), ICC ≤40 µA (max) over full temperature range, and USV (SOT-353) package compatibility with high-density PCB layouts.
Technical Context
This device implements a CMOS-based Schmitt-trigger input stage followed by a push-pull output buffer, providing clean digital signal regeneration in electrically noisy environments. Its hysteresis (VP − VN ≥ 0.5 V) rejects sub-threshold noise without external components, while TTL-compatible output drive (±8 mA) ensures interoperability with legacy logic families.
The TC7SET17FTE85LF is optimized for unidirectional signal conditioning in automotive subsystems where input signals originate from analog sensors, switches, or open-collector sources. Its 5.5 V input tolerance allows direct connection to 5 V rails even when VCC = 4.5 V, eliminating level-shifter requirements in supply-varied domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures stable operation across automotive battery variations (e.g., cold-crank dips to 4.5 V). |
| Propagation Delay | 5.0 ns (typ.) at VCC = 5.0 V, CL = 15 pF - Enables timing-critical signal routing in real-time control loops. |
| Hysteresis Voltage | ≥0.5 V (min) - Rejects up to ±250 mV of common-mode noise on slow-rising sensor outputs. |
| Input Tolerance | −0.5 V to 5.5 V - Permits direct interface with 5 V logic or analog sources exceeding VCC without clamping diodes. |
| Quiescent Current | ≤40 µA (max) at −40°C to +125°C - Supports always-on monitoring circuits with ultra-low standby power budgets. |
| Output Drive | ±8 mA - Sufficient to drive multiple 74HC inputs or short PCB traces without buffering. |
| Operating Temp | −40°C to +125°C - Qualified for under-hood automotive locations per AEC-Q100 Rev. H. |
Pinout & Package
TC7SET17FTE85LF is housed in a USV package (JEDEC SOT-353), measuring 2.0 × 1.25 × 0.9 mm with 0.65 mm lead pitch and a typical weight of 0.006 g. This ultra-small outline supports high-density placement in space-constrained modules such as body control units and ADAS sensor nodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (A) | Schmitt-trigger input accepting 5.5 V tolerant signals; must be tied to VCC or GND if unused. |
| 2 | GND | Ground reference for all internal circuitry and output stage return path. |
| 3 | Output (Y) | Push-pull CMOS output capable of sourcing/sinking ±8 mA; compatible with TTL and CMOS loads. |
| 4 | VCC | Positive supply rail (4.5–5.5 V); decoupling capacitor recommended within 5 mm. |
| 5 | N/C | No internal connection; left floating or grounded per layout best practices (no electrical function). |

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 hysteresis (≈0.3 V); not AEC-Q100 qualified. | Targeted at commercial portable electronics; lacks automotive reliability validation. | Select when cost or multi-supply flexibility outweighs automotive qualification requirements. |
| NC7SZ17P5X | Same USV package; AEC-Q100 Grade 2 (−40°C to +105°C); higher ICC (≤100 µA at +105°C). | Limited to under-dash automotive applications; insufficient for under-hood thermal profiles. | Choose only for non-engine-bay modules where extended temperature margin is unnecessary. |
Compared with SN74LVC1G17DBVR and NC7SZ17P5X, the TC7SET17FTE85LF uniquely combines AEC-Q100 Rev. H qualification, −40°C to +125°C operation, and ≤40 µA max ICC across that full range-making it the sole option for high-reliability engine compartment signal conditioning.

FAQ
What is the AEC-Q100 qualification status of TC7SET17FTE85LF?
The TC7SET17FTE85LF is fully compliant with AEC-Q100 Revision H, including stress testing for temperature cycling, humidity bias, and high-temperature operating life. This qualification confirms its suitability for automotive powertrain and chassis applications where reliability under thermal and electrical stress is critical. Documentation is available through Toshiba sales representatives upon request.
Does TC7SET17FTE85LF support operation at 4.5 V supply?
Yes, TC7SET17FTE85LF is fully specified to operate at VCC = 4.5 V across its entire temperature range (−40°C to +125°C), maintaining tPLH/tPHL ≤9.5 ns and VOH ≥4.4 V (min) at IOH = −50 µA. This ensures robust functionality during automotive cold-crank conditions where battery voltage sags to nominal 4.5 V.
What is the meaning of the "FTE85LF" suffix in TC7SET17FTE85LF?
The "FTE85LF" suffix denotes Toshiba's standard automotive-grade marking: "FT" indicates tape-and-reel packaging, "E85" specifies the −40°C to +125°C operating range, and "LF" confirms lead-free (RoHS-compliant) construction. This matches the USV package and AEC-Q100 qualification detailed in the official datasheet.
Can TC7SET17FTE85LF drive a 15 pF load with 5.0 ns delay?
Yes, TC7SET17FTE85LF achieves 5.0 ns typical propagation delay (tPLH/tPHL) under test conditions of VCC = 5.0 V ±0.5 V and CL = 15 pF, as confirmed in Section 9.4 of the datasheet. This performance is guaranteed across the full operating temperature range, supporting precise timing in real-time control subsystems.
Is Pin 5 of TC7SET17FTE85LF internally connected?
No, Pin 5 of TC7SET17FTE85LF is a no-connect (N/C) terminal with no internal bond wire or silicon connection. It may be left floating or grounded per PCB layout guidelines but contributes no electrical function. This is explicitly documented in Toshiba's pin assignment diagram and package drawings for the USV (SOT-353) variant.
