Product details
Overview
TC7SH34FU(T5L,F,T) from Toshiba Electronic Devices & Storage Corporation is a single-channel non-inverting CMOS buffer IC designed for signal conditioning and level translation in space-constrained automotive and industrial control systems. It operates across 2.0–5.5 V supply, delivers 3.8 ns typical propagation delay at 5.0 V/15 pF, supports AEC-Q100 Grade 1 qualification, and features 5.5 V tolerant inputs.
For engineers reviewing the TC7SH34FU(T5L,F,T) datasheet, TC7SH34FU(T5L,F,T) pinout, TC7SH34FU(T5L,F,T) application, or TC7SH34FU(T5L,F,T) equivalent, key selection criteria include wide temperature operation (−40 to +125 °C), ultra-low ICC (2.0 µA max at 25 °C), high noise immunity (28% VCC min), and USV (SOT-353) package compatibility with high-density PCB layouts.
Technical Context
The TC7SH34FU(T5L,F,T) implements a single-stage CMOS inverter-based buffer topology with rail-to-rail input voltage tolerance up to 5.5 V independent of VCC. Its output stage provides symmetrical drive capability (±4 mA at 3.0 V, ±8 mA at 4.5 V) and maintains logic-level integrity across full VCC range.
Designed for automotive-grade reliability, the device meets AEC-Q100 Rev. H stress testing requirements and specifies guaranteed DC/AC performance over −40 to +125 °C, with VIH/VIL thresholds defined as percentages of VCC (70%/30%) and absolute minimums (1.5 V/0.5 V) ensuring robust interfacing with mixed-voltage subsystems.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar non-inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DBVR | Open-drain output; requires external pull-up; no 5.5 V input tolerance | Suitable only where active-low open-drain signaling is needed (e.g., I²C bus driving) | Select only when pull-up biasing and voltage-level flexibility are acceptable trade-offs for cost reduction |
| NC7SZ17P5X | Higher ICC (10 µA max); narrower temp range (−40 to +85 °C); same USV package | Limited to commercial/industrial use; not AEC-Q100 qualified | Acceptable for non-automotive designs where qualification and ultra-low ICC are not mandatory |
Compared with SN74LVC1G07DBVR and NC7SZ17P5X, TC7SH34FU(T5L,F,T) uniquely combines AEC-Q100 Grade 1 qualification, 5.5 V input tolerance, and sub-µA quiescent current-making it the only choice for automotive body electronics requiring both reliability and power efficiency.

FAQ
What is the maximum operating temperature for TC7SH34FU(T5L,F,T)?
The TC7SH34FU(T5L,F,T) is rated for continuous operation from −40 °C to +125 °C, meeting AEC-Q100 Grade 1 requirements. This specification is validated across all electrical parameters including propagation delay, VOH/VOL, and ICC, making TC7SH34FU(T5L,F,T) suitable for under-hood automotive applications and high-ambient industrial environments.
Does TC7SH34FU(T5L,F,T) support 5 V logic interfacing with a 3.3 V supply?
Yes. TC7SH34FU(T5L,F,T) features 5.5 V tolerant inputs, allowing direct connection to 5 V signal sources while powered from a 3.3 V supply. Input thresholds remain valid (VIH ≥ 70% VCC, VIL ≤ 30% VCC), and no external level-shifting components are required-enabling clean integration of TC7SH34FU(T5L,F,T) into mixed-voltage systems.
Is TC7SH34FU(T5L,F,T) pin-compatible with other USV-packaged buffers?
TC7SH34FU(T5L,F,T) uses the standard 5-pin USV (SOT-353) footprint with pin 1 = Input, pin 2 = GND, pin 3 = Output, pin 4 = VCC, pin 5 = N/C. While physical dimensions match JEDEC SOT-353, functional pinout differs from open-drain variants (e.g., SN74LVC1G07). Always verify pin function-not just package-before substitution; TC7SH34FU(T5L,F,T) is not a drop-in replacement for open-drain buffers.
What is the typical propagation delay of TC7SH34FU(T5L,F,T) at 3.3 V?
At VCC = 3.3 V and CL = 15 pF, the typical propagation delay (tPLH/tPHL) of TC7SH34FU(T5L,F,T) is 5.0 ns, with a maximum of 7.1 ns over temperature and process variation. This value is measured under standardized conditions (input rise/fall time = 3 ns) and confirms TC7SH34FU(T5L,F,T)'s suitability for sub-100 MHz digital signal routing in timing-sensitive applications.
Can unused inputs on TC7SH34FU(T5L,F,T) be left floating?
No. Per Toshiba's operating guidelines, unused inputs on TC7SH34FU(T5L,F,T) must be tied to either VCC or GND to prevent undefined logic states, increased ICC, and potential oscillation. The device has no internal pull-up or pull-down resistors; leaving pin 1 (Input) unconnected violates the Absolute Maximum Ratings and may cause erratic behavior or accelerated wear. Always terminate TC7SH34FU(T5L,F,T) inputs explicitly.
