Product details
Overview
TC7SH34FU from Toshiba Electronic Devices & Storage Corporation is a single-channel non-inverting CMOS buffer IC designed for signal conditioning and level translation in low-power digital systems. It operates from 2.0 V to 5.5 V, delivers 3.8 ns typical propagation delay at 5.0 V/15 pF, supports AEC-Q100 qualification, and functions across -40 °C to +125 °C for automotive under-hood applications.
For engineers reviewing the TC7SH34FU datasheet, TC7SH34FU pinout, TC7SH34FU application, or TC7SH34FU equivalent, this page provides verified electrical specifications, USV (SOT-353) package details, temperature-grade validation, input tolerance (5.5 V), and real-world use cases in automotive control modules, industrial sensor interfaces, and battery-powered logic isolation circuits.
Technical Context
The TC7SH34FU implements a single-stage CMOS non-inverting buffer with rail-to-rail output swing and Schmitt-trigger–free input structure. Its design targets low-noise, high-immunity signal buffering where input voltage may exceed VCC-enabled by 5.5 V tolerant inputs independent of supply voltage.
It features ultra-low quiescent current (2.0 µA max at 25 °C) and high noise immunity (28 % VCC min VIH/VIL hysteresis margin), making it suitable for always-on subsystems in automotive ECUs and industrial controllers requiring stable logic-level translation across wide VCC and temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Single non-inverting buffer with no internal hysteresis |
| Supply Voltage Range | 2.0 V to 5.5 V - enables direct interface with 3.3 V and 5 V logic families |
| Propagation Delay | 3.8 ns typ. at VCC = 5.0 V, CL = 15 pF - supports >100 MHz toggle rates in clean signal paths |
| Input Tolerance | 5.5 V tolerant inputs - allows mixed-voltage system interfacing without external level shifters |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Rev. H for automotive powertrain and chassis modules |
| Quiescent Current | 2.0 µA max at 25 °C - enables use in battery-backed or energy-harvesting subsystems |
| Noise Immunity | VNIH/VNIL ≥ 28 % VCC - reduces susceptibility to ground bounce and EMI in noisy environments |
Pinout & Package
TC7SH34FU is housed in a 5-pin USV package (JEDEC SOT-353), measuring 2.0 × 2.1 × 0.9 mm with 0.5 mm pitch and gull-wing leads. The package is halogen-free, RoHS-compliant, and optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (A) | CMOS-compatible digital input; 5.5 V tolerant, accepts logic levels independent of VCC |
| 2 | GND | Ground reference for both input and output stages; must be low-impedance for noise immunity |
| 3 | Output (Y) | Push-pull CMOS output; rail-to-rail swing, drives 4 mA sink/source at VCC = 4.5 V |
| 4 | VCC | Positive supply rail; decoupling capacitor (0.1 µF) required within 5 mm for stable AC performance |
| 5 | No Connect (NC) | Internally unconnected; must remain floating or tied to GND per layout best practice |

Equivalent & Alternatives
The following parts are listed as comparable options for similar non-inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVR | Includes Schmitt-trigger input hysteresis; 3.3 V optimized (1.65–5.5 V); 5.5 V input tolerant | Better noise rejection in slow-rising signals (e.g., mechanical switches); less suitable for high-speed clock forwarding | Select when input signals exhibit slow edges or high EMI; avoid if precise propagation delay matching is required |
| 74AUP1G07GW,125 | Lower ICC (0.9 µA typ.); 0.8–3.6 V VCC range; not AEC-Q100 qualified; 3.6 V input tolerant | Optimized for sub-3.3 V portable systems; lacks automotive temperature grade and 5.5 V tolerance | Select for consumer wearables or handhelds where extended temperature range and high-voltage tolerance are unnecessary |
Compared with SN74LVC1G17DBVR and 74AUP1G07GW,125, the TC7SH34FU uniquely combines AEC-Q100 Grade 1 qualification, 5.5 V input tolerance, and 3.8 ns propagation delay in a USV package-making it the only choice for automotive signal buffering where voltage interoperability and high-temperature reliability are mandatory.

FAQ
What is the maximum operating temperature for the TC7SH34FU?
The TC7SH34FU is rated for operation from -40 °C to +125 °C and is AEC-Q100 Rev. H qualified for automotive Grade 1 applications. This rating applies specifically to units with ordering code ending in J(CT, as confirmed in the official Toshiba datasheet Rev. 3.0.B. Units without the J(CT suffix have an 85 °C upper limit.
Does the TC7SH34FU require external pull-up or pull-down resistors on its input?
No, the TC7SH34FU does not require external pull-up or pull-down resistors on its input. Its CMOS input structure has negligible leakage (±0.1 µA max), and unused inputs must be tied to VCC or GND per Toshiba's operating range guidelines-not left floating-to prevent undefined states and increased ICC.
Is the TC7SH34FU pin-compatible with other SOT-353 logic buffers?
The TC7SH34FU uses standard SOT-353 (USV) pinout: Pin 1 = Input, Pin 2 = GND, Pin 3 = Output, Pin 4 = VCC, Pin 5 = NC. While physical footprint matches other SOT-353 logic devices, functional pin mapping differs across manufacturers; therefore, TC7SH34FU is not guaranteed pin-compatible with non-Toshiba SOT-353 buffers without verifying signal assignment and electrical behavior.
Can the TC7SH34FU drive a 50 pF load at 5.0 V supply?
Yes, the TC7SH34FU can drive a 50 pF load at 5.0 V supply: its AC characteristics specify tPLH/tPHL ≤ 7.5 ns (typ.) and ≤ 10.6 ns (max) under those conditions. Output drive capability remains sufficient (IOH/IOL ≥ ±4 mA) to maintain logic thresholds and edge integrity across the full -40 °C to +125 °C range.
What is the purpose of the NC pin (Pin 5) on the TC7SH34FU?
Pin 5 on the TC7SH34FU is a No Connect terminal-internally unconnected and electrically isolated. Toshiba recommends leaving it floating or connecting it to GND during PCB layout to minimize parasitic coupling; it must never be connected to VCC or driven by external circuitry, as this violates absolute maximum ratings and may compromise device reliability.
