Product details
Overview
TC7SET34FU,LJ(CT) from Toshiba Electronic Devices & Storage Corporation is a single-channel CMOS non-inverting buffer IC in USV (SOT-353) package, delivering 5.0 ns typical propagation delay at 5.0 V/15 pF, 2.0 µA max quiescent current, and AEC-Q100 Rev. H compliance for automotive signal conditioning applications.
For engineers reviewing the TC7SET34FU,LJ(CT) datasheet, TC7SET34FU,LJ(CT) pinout, TC7SET34FU,LJ(CT) application, or TC7SET34FU,LJ(CT) equivalent, key selection criteria include its -40 to 125 °C operating range (J(CT suffix), 5.5 V tolerant inputs, TTL-compatible thresholds, and low-power high-speed logic buffering in space-constrained automotive ECUs and industrial control interfaces.
Technical Context
This device implements a single non-inverting buffer stage using Toshiba's silicon monolithic CMOS process, optimized for level translation and signal integrity preservation across mixed-voltage domains. It supports rail-to-rail input operation up to 5.5 V while maintaining full compatibility with 5 V TTL logic families.
The TC7SET34FU,LJ(CT) features internally compensated output drive capability (±8 mA), guaranteed DC performance over -40 to 125 °C, and AC timing validated under 3 ns input edge rates with 15 pF load - enabling reliable use in CAN/LIN bus interface buffers, sensor signal conditioning chains, and microcontroller GPIO expansion circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Non-inverting buffer: passes input signal unchanged with gain = 1 and no phase inversion. |
| Propagation Delay | 5.0 ns typ. (VCC = 5.0 V, CL = 15 pF): enables sub-10 ns timing margins in 50 MHz+ digital control loops. |
| Supply Voltage Range | 4.5–5.5 V: matches standard 5 V system rails and accommodates ±10% regulation tolerance. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC: allows safe interfacing with higher-voltage peripherals without external clamping. |
| Quiescent Current | 2.0 µA max at 25 °C: supports always-on monitoring nodes with negligible standby power impact. |
| Operating Temperature | -40 to 125 °C (J(CT suffix): qualified for under-hood automotive environments per AEC-Q100 Rev. H. |
| Output Drive | ±8 mA (VOH/VOL guaranteed): sufficient to drive multiple 74LVC inputs or short PCB traces without fanout limitation. |
Pinout & Package
TC7SET34FU,LJ(CT) uses the USV package - a 5-pin ultra-small leadless surface-mount package (JEDEC SOT-353), measuring 2.0 × 2.1 × 0.9 mm with 0.5 mm pitch and 0.006 g typical weight. Designed for high-density automotive PCB layouts where thermal and space constraints are critical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (A) | CMOS/TTL-compatible digital input; accepts 0–5.5 V signals regardless of VCC level. |
| 2 | GND | Ground reference for all internal circuitry and output return path. |
| 3 | Output (Y) | Push-pull CMOS output capable of sourcing/sinking ±8 mA with rail-aligned VOH/VOL. |
| 4 | VCC | Positive supply terminal; must be decoupled locally to suppress switching noise. |
| 5 | No Connect (NC) | Internally unconnected; must remain floating or tied to GND per layout best practice. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Rev. H qualified | Validated for automotive-grade reliability including HTOL, TC, ESD, and latch-up testing - suitable for engine control, body electronics, and ADAS subsystems. |
| 5.5 V tolerant inputs | Enables direct connection to 5 V or 3.3 V microcontrollers without level shifters, reducing BOM count and board area in mixed-voltage systems. |
| Low ICC (2.0 µA max) | Minimizes system-level standby current in battery-backed modules such as telematics wake-up receivers or smart sensors. |
| TTL-compatible VIH/VIL | VIH ≥ 2.0 V / VIL ≤ 0.8 V ensures interoperability with legacy 74LS/74HC families and avoids false triggering in noisy industrial environments. |
| High-speed tPD = 5.0 ns | Supports clean signal transmission in time-critical paths like PWM gate drivers, encoder feedback lines, and real-time interrupt routing. |
Applications
| Automotive Body Control Module | Industrial PLC I/O Expansion |

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 (no pull-up required), 3.6 V max VCC, -40 to 125 °C, 3.7 ns tPD @ 3.3 V. | Lacks push-pull drive and 5.5 V input tolerance; requires external pull-up for logic-high assertion. | Prefer when interfacing with I²C or wired-OR buses; avoid where active-high drive or 5 V signal handling is needed. |
| 74AUP1G07GW,125 | Lower ICC (0.9 µA typ.), 3.3 V max VCC, -40 to 125 °C, 6.3 ns tPD @ 3.3 V, smaller XSON-6 package. | Not 5 V tolerant; incompatible with 5 V systems without level translation. | Select for ultra-low-power 3.3 V IoT endpoints; unsuitable for automotive 5 V domains or mixed-voltage signal routing. |
Compared with SN74LVC1G07DBVR and 74AUP1G07GW,125, the TC7SET34FU,LJ(CT) uniquely combines 5.5 V input tolerance, push-pull 5 V operation, AEC-Q100 qualification, and USV packaging - making it the only drop-in solution for space-constrained, high-reliability 5 V automotive buffer applications requiring no external components.

FAQ
What is the operating temperature range for TC7SET34FU,LJ(CT)?
The TC7SET34FU,LJ(CT) is rated for -40 to 125 °C operation, confirmed by AEC-Q100 Rev. H qualification. This range applies specifically to parts with the J(CT suffix, as noted in Toshiba's datasheet Section 8. Operating Ranges (Note 2). Units without the J(CT suffix are limited to -40 to 85 °C.
Does TC7SET34FU,LJ(CT) support 5 V tolerant inputs?
Yes, TC7SET34FU,LJ(CT) supports input voltages up to 5.5 V regardless of VCC level, as specified in Section 7 Absolute Maximum Ratings and Section 2 Features (item 5). This eliminates the need for external clamping diodes when interfacing with higher-voltage peripherals or legacy 5 V logic.
What is the maximum output drive capability of TC7SET34FU,LJ(CT)?
The TC7SET34FU,LJ(CT) delivers ±8 mA output current, verified under VOH and VOL test conditions in Section 9.1 DC Characteristics. This allows direct driving of multiple LVC inputs or short PCB traces without external buffering, supporting fanout >10 into standard CMOS loads.
Is TC7SET34FU,LJ(CT) pin-compatible with other SOT-353 logic buffers?
TC7SET34FU,LJ(CT) uses the standard SOT-353 (USV) 5-pin footprint with pin 1 = Input, pin 2 = GND, pin 3 = Output, pin 4 = VCC, pin 5 = NC. While mechanical footprint matches, functional pinout differs from open-drain variants (e.g., SN74LVC1G07), so electrical compatibility must be verified per application.
What packaging format does TC7SET34FU,LJ(CT) use?
TC7SET34FU,LJ(CT) is supplied in tape-and-reel format (CT suffix), packaged in the USV (JEDEC SOT-353) 5-pin ultra-small surface-mount package. Dimensions are 2.0 × 2.1 × 0.9 mm with 0.5 mm lead pitch, optimized for automated placement in high-density automotive PCB assemblies.
