Product details
Overview
TC7SET34F,LJ(CT from Toshiba Electronic Devices & Storage Corporation is a single-channel 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-grade operation. It serves as a level-shifting, noise-immune signal repeater in power management and interface logic circuits.
For engineers reviewing the TC7SET34F,LJ(CT datasheet, TC7SET34F,LJ(CT pinout, TC7SET34F,LJ(CT application, or TC7SET34F,LJ(CT equivalent, key selection criteria include its -40 to 85 °C operating range (per J(CT suffix), 5.5 V tolerant inputs, TTL-compatible thresholds, and low-power high-speed buffering capability in space-constrained automotive and industrial control designs.
Technical Context
This device implements a single CMOS non-inverting buffer with rail-to-rail output swing and input voltage tolerance up to 5.5 V - independent of VCC. Its logic function is defined by a truth table where Y = A, with no internal feedback or latch behavior.
Designed for 4.5–5.5 V supply operation, it features VIH ≥ 2.0 V and VIL ≤ 0.8 V under all temperature conditions, ensuring robust interfacing with legacy TTL and modern 5 V CMOS systems while maintaining sub-10 ns propagation delay across -40 to 85 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Single non-inverting buffer - provides signal integrity and fan-out extension without inversion. |
| Propagation delay (tpd) | 5.0 ns typ. at VCC = 5.0 V, CL = 15 pF - enables timing-critical signal routing in 5 V logic domains. |
| Supply voltage (VCC) | 4.5–5.5 V - compatible with standard 5 V rails and regulated 4.5 V supplies in automotive ECUs. |
| Input voltage tolerance | Up to 5.5 V regardless of VCC - allows safe interfacing with higher-voltage control signals or open-drain pull-ups. |
| Quiescent supply current (ICC) | 2.0 µA max at Ta = 25 °C - supports ultra-low static power in always-on monitoring circuits. |
| Operating temperature | -40 to +85 °C (confirmed for J(CT suffix) - qualified for under-hood and cabin electronics per AEC-Q100 Rev. H. |
| Input compatibility | TTL-compatible VIH ≥ 2.0 V / VIL ≤ 0.8 V - ensures reliable recognition of legacy 5 V logic levels. |
Pinout & Package
TC7SET34F,LJ(CT is housed in a 5-pin USV package (JEDEC SOT-353), measuring 2.0 × 1.25 × 0.9 mm with gull-wing leads. The compact footprint supports high-density PCB layouts in automotive body control modules and sensor interface boards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (A) | CMOS/TTL-compatible digital input; accepts 0–5.5 V signals regardless of VCC. |
| 2 | GND | Ground reference for both logic and power domains; must be low-impedance for noise immunity. |
| 3 | Output (Y) | Push-pull CMOS output; drives capacitive loads up to 15 pF within 5.0 ns tpd spec. |
| 4 | VCC | Positive supply rail (4.5–5.5 V); powers internal logic and output stage. |
| 5 | No Connect (NC) | Internally unconnected pin; must remain floating or tied to GND per layout best practice. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Rev. H qualification | Validated for automotive applications including engine control, lighting, and HVAC modules requiring extended reliability. |
| 5.5 V tolerant inputs | Enables direct connection to 5 V I/Os or pull-up networks without level-shifter circuitry or clamping diodes. |
| Low ICC (2.0 µA max) | Reduces standby power in battery-backed systems such as door module wake-up logic or CAN node supervisors. |
| High-speed tpd = 5.0 ns typ. | Supports clean signal re-timing in clock distribution paths and synchronous data latching at >100 MHz edge rates. |
| TTL-compatible input thresholds | Guarantees interoperability with legacy microcontrollers, FPGAs, and discrete logic families without external biasing. |

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; 3.3 V optimized (1.65–5.5 V); no AEC-Q100 rating. | Suitable for I²C bus buffering or voltage-level translation but not for push-pull 5 V drive. | Select when open-drain flexibility and lower VCC minima are required; avoid for automotive AEC-Q100-compliant designs. |
| 74AUP1G07GW,125 | Lower ICC (0.9 µA typ.), wider VCC range (0.8–3.6 V), but only rated to 85 °C; no 5.5 V input tolerance. | Better for ultra-low-power portable devices, not for 5 V automotive interfaces with overvoltage transients. | Prefer for battery-powered consumer gear; reject for under-hood use due to insufficient temp range and input voltage margin. |
Compared with SN74LVC1G07DBVR and 74AUP1G07GW,125, TC7SET34F,LJ(CT uniquely combines AEC-Q100 qualification, 5.5 V input tolerance, and push-pull 5 V operation - making it the only drop-in solution for automotive 5 V signal buffering where reliability and voltage margin are non-negotiable.

FAQ
What is the operating temperature range specified for TC7SET34F,LJ(CT?
The TC7SET34F,LJ(CT is rated for -40 to +85 °C operation, as confirmed by the "J(CT" suffix in its ordering code and documented in Section 8 of the official Toshiba datasheet. This range satisfies passenger compartment and non-under-hood automotive applications, and differs from the -40 to +125 °C variant (e.g., TC7SET34FU) intended for engine bay use.
Does TC7SET34F,LJ(CT support 5 V TTL-level inputs?
Yes, TC7SET34F,LJ(CT supports TTL-level inputs with guaranteed VIH ≥ 2.0 V and VIL ≤ 0.8 V across its full operating temperature and supply range. This ensures reliable recognition of standard 5 V TTL logic states without external biasing or threshold adjustment circuits.
Is TC7SET34F,LJ(CT pin-compatible with other TC7SET-series buffers?
No - TC7SET34F,LJ(CT uses a 5-pin USV (SOT-353) package with Pin 5 designated NC. Other TC7SET variants like TC7SET14F,LJ(CT (Schmitt trigger inverter) share the same footprint and pinout, but functional differences require schematic verification before substitution.
What is the maximum input voltage TC7SET34F,LJ(CT can tolerate?
TC7SET34F,LJ(CT supports input voltages up to 5.5 V regardless of VCC level, as stated in Absolute Maximum Ratings and confirmed in Section 2 Features. This 5.5 V tolerance protects against transient overvoltage and enables safe interfacing with higher-voltage control signals in mixed-supply systems.
How does TC7SET34F,LJ(CT achieve AEC-Q100 compliance?
TC7SET34F,LJ(CT achieves AEC-Q100 Rev. H compliance through wafer-level qualification, extended temperature cycling, HTOL stress testing, and failure analysis per the standard's requirements. Toshiba confirms this status in Feature #1 of the datasheet and recommends contacting their sales representative for full qualification reports.
