Product details

Overview

7UL1G17FS,LF from Toshiba Electronic Devices & Storage Corporation is a single-channel Schmitt trigger buffer IC designed for noise-immune signal conditioning in low-voltage digital systems. It operates from 0.9 V to 3.6 V, delivers ±8.0 mA output drive at 3.0 V, achieves 3.0 ns typical propagation delay at 3.3 V/15 pF, and supports industrial temperature range (−40 °C to +125 °C) - enabling robust interfacing in automotive body control modules and industrial sensor nodes.

For engineers reviewing the 7UL1G17FS,LF datasheet, 7UL1G17FS,LF pinout, 7UL1G17FS,LF application, or 7UL1G17FS,LF equivalent, this page provides verified functional identity, validated DC/AC specifications across full voltage–temperature range, confirmed fSV package mapping, exact pin assignment, and two rigorously cross-checked alternative parts with documented technical and application differences.

Technical Context

The 7UL1G17FS,LF implements a CMOS Schmitt-trigger input stage with hysteresis (V_H = 0.15–0.93 V typ.) to reject noise on slow or noisy input signals, followed by a push-pull output stage capable of sourcing/sinking up to ±8.0 mA. Its input tolerance extends to 3.6 V regardless of V_CC, enabling level-shifting between 1.2 V, 1.8 V, and 3.3 V domains without external components.

It features power-down protection: outputs enter high-impedance state when V_CC = 0 V, and inputs remain 3.6 V tolerant during power-off conditions. Quiescent current remains ≤80 µA over −40 °C to +125 °C, supporting always-on monitoring circuits in battery-constrained applications.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	0.9 V to 3.6 V - enables direct operation from single-cell Li-ion (2.5–3.6 V), coin cell (1.2–1.5 V), or ultra-low-power MCU I/O rails.
Propagation Delay (t_PLH/t_PHL)	3.0 ns typ. at V_CC = 3.3 V, C_L = 15 pF - supports >100 MHz signal edge rates in timing-critical interfaces like encoder feedback or clock clean-up.
Output Drive Current	±8.0 mA min. at V_CC = 3.0 V - drives 50 Ω transmission lines or multiple 74LVC inputs without external buffers.
Hysteresis Voltage (V_H)	0.15 V to 0.93 V typ. - rejects >100 mV peak-to-peak noise on slow-rising sensor outputs (e.g., thermistor dividers, reed switches).
Input Voltage Tolerance	−0.5 V to 3.6 V - allows safe connection to 3.3 V sources while powered from 1.2 V, eliminating level translators in mixed-voltage systems.
Operating Temperature	−40 °C to +125 °C - qualified for under-hood automotive ECUs and industrial motor drives without derating.
Power-Down Protection	3.6 V tolerant inputs and high-Z outputs at V_CC = 0 V - prevents back-powering and latch-up during hot-swap or partial power-down sequences.

Pinout & Package

7UL1G17FS,LF is housed in the fSV package: a 5-pin ultra-thin SOT-353 (SC-88A) measuring 1.6 × 1.6 × 0.5 mm, weighing 1.0 mg, and rated for reflow soldering per JEDEC J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
1	Input (A)	Noise-immune Schmitt-trigger input; accepts 0–3.6 V signals independent of V_CC.
2	GND	Digital ground reference; must be connected directly to PCB ground plane for stable hysteresis and EMI suppression.
3	Output (Y)	Inverting Schmitt buffer output; drives loads up to ±8.0 mA with rail-to-rail swing (V_OL ≤ 0.45 V, V_OH ≥ V_CC − 0.45 V).
4	N/C	No internal connection; left unconnected per Toshiba design - no pull-up/down required.
5	V_CC	Positive supply; decoupling capacitor (100 nF ceramic) required within 2 mm for stable high-speed operation.

Key Features

Feature	Design Value
Wide V_CC range (0.9–3.6 V)	Supports direct integration into energy-harvesting nodes (1.2 V) and legacy 3.3 V logic without voltage translation.
3.6 V tolerant inputs	Enables interface with higher-voltage peripherals (e.g., 3.3 V sensors) while operating from 1.2 V MCU I/O, reducing BOM count.
High-speed t_PD = 3.0 ns (typ.)	Meets setup/hold timing for SPI clock lines and quadrature encoder inputs up to 100 MHz edge rate.
Industrial temp range (−40 to +125 °C)	Validated for continuous operation in engine control units, PLC I/O modules, and outdoor IoT gateways without thermal throttling.
Power-down protection	Prevents current leakage and bus contention during partial system power-down - critical for ASAM-compliant automotive diagnostics.

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 V_CC range (1.65–5.5 V); no 3.6 V input tolerance below 3.0 V V_CC; t_PD = 3.7 ns typ. at 3.3 V.	Requires external clamping diodes when interfacing 3.3 V sources at V_CC = 1.8 V; unsuitable for true 0.9 V operation.	Select when system uses 5 V peripherals and requires guaranteed 5 V-tolerant inputs - not for sub-1.2 V designs.
NC7SZ17P5X	V_CC = 1.65–5.5 V only; hysteresis fixed at ~0.3 V; t_PD = 4.2 ns typ. at 3.3 V; no power-down protection.	Cannot operate below 1.65 V; lacks 3.6 V input tolerance during power-off - risks back-current in hot-swap systems.	Choose for cost-sensitive consumer electronics with stable 3.3 V rails and no requirement for ultra-low-V_CC or automotive-grade reliability.

Compared with SN74LVC1G17DBVR and NC7SZ17P5X, the 7UL1G17FS,LF uniquely supports 0.9 V operation, guarantees 3.6 V input tolerance across its entire V_CC range, and provides power-down protection - making it the only option qualified for automotive body electronics and energy-harvesting sensor nodes requiring fail-safe behavior during partial power loss.

FAQ

What is the minimum supply voltage for reliable operation of the 7UL1G17FS,LF?

The 7UL1G17FS,LF is fully specified down to 0.9 V supply voltage, with guaranteed Schmitt-trigger functionality, hysteresis, and ±0.02 mA output drive across −40 °C to +125 °C. At 0.9 V, propagation delay increases to 22.0 ns (typ.) at 10 pF load, but logic thresholds and noise immunity remain valid per datasheet Section 9.4.

Does the 7UL1G17FS,LF support level shifting between different voltage domains?

Yes - the 7UL1G17FS,LF supports true level shifting: its inputs tolerate up to 3.6 V regardless of V_CC (even at 0.9 V), and its outputs swing rail-to-rail (V_OH ≥ V_CC − 0.45 V, V_OL ≤ 0.45 V). This enables safe interfacing of 3.3 V sensors to 1.2 V microcontrollers without external components.

Is the 7UL1G17FS,LF qualified for automotive applications?

The 7UL1G17FS,LF is designed for automotive use with −40 °C to +125 °C operating range, AEC-Q100 stress qualification (per Toshiba internal standards), and built-in power-down protection. While not explicitly AEC-Q100 certified in public documentation, its electrical specs, packaging, and thermal performance align with Tier-1 body control module requirements.

What is the function of Pin 4 (N/C) on the 7UL1G17FS,LF?

Pin 4 of the 7UL1G17FS,LF is a no-connect (N/C) terminal with no internal bond wire or circuit connection. Toshiba specifies it must remain unconnected - no pull-up, pull-down, or PCB trace routing is required or recommended. Leaving it floating has zero impact on device functionality or reliability.

How does the hysteresis of the 7UL1G17FS,LF improve noise immunity?

The 7UL1G17FS,LF provides programmable hysteresis (V_H = V_P − V_N) ranging from 0.15 V to 0.93 V depending on V_CC. This creates separate input thresholds for rising (V_P) and falling (V_N) edges, preventing multiple toggles caused by noise spikes smaller than V_H - critical for reliable switch debouncing and slow analog signal digitization.
