Product details
Overview
TC7SET125F,LJ(CT from Toshiba Electronic Devices & Storage Corporation is a single-channel 3-state bus buffer IC designed for high-speed digital signal routing in automotive and industrial control systems. It features 3.7 ns typical propagation delay at 5.0 V/15 pF, 5.5 V tolerant inputs, and AEC-Q100 Rev. H qualification for automotive use.
For engineers reviewing the TC7SET125F,LJ(CT datasheet, TC7SET125F,LJ(CT pinout, TC7SET125F,LJ(CT application, or TC7SET125F,LJ(CT equivalent, this device serves as a low-power, high-speed unidirectional buffer with TTL-compatible input thresholds and rail-to-rail output drive capability in SOT-25 (SMV) packaging.
Technical Context
The TC7SET125F,LJ(CT implements a single non-inverting 3-state buffer with active-low output enable (G). Its logic function is defined by truth table entries where G = L enables Y = A, and G = H places Y in high-impedance state - no internal latching or clocking circuitry is present.
Designed for 4.5–5.5 V operation, it supports wide temperature range (-40 to +125 °C) per AEC-Q100 Rev. H, with input voltage tolerance up to 5.5 V independent of VCC and guaranteed VIH ≥ 2.0 V / VIL ≤ 0.8 V for TTL-level compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 3.7 ns typ. at VCC = 5.0 V, CL = 15 pF - enables sub-5 ns timing-critical data path buffering |
| Supply voltage range | 4.5–5.5 V - compatible with standard 5 V logic rails and regulated 5 V supplies |
| Input voltage tolerance | Up to 5.5 V - allows interfacing with higher-voltage peripherals without level shifters |
| Quiescent current | 2.0 µA max at Ta = 25 °C - supports ultra-low static power in always-on subsystems |
| Operating temperature | -40 to +125 °C - qualified for under-hood automotive and industrial ambient environments |
| Output drive strength | ±8 mA - sufficient to drive 15 pF loads with <7.5 ns max delay across full temp range |
| 3-state leakage | 0.1 µA max - ensures minimal bus contention during high-Z state in shared-bus architectures |
Pinout & Package
SOT-25 (JEDEC) package, also designated SMV by Toshiba, measuring 2.9 × 1.6 × 1.1 mm with 5 terminals. Weight: 14 mg (typ.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Output enable (active-low) | Drives output Y into high-impedance when logic high; enables pass-through when logic low |
| 2 (A) | Data input | Non-inverting input signal source; accepts TTL- and CMOS-compatible logic levels |
| 3 (GND) | Ground reference | Primary return path for supply and signal currents; must be low-impedance connection |
| 4 (Y) | 3-state buffered output | Drives external load only when G = L; presents high-Z impedance when G = H |
| 5 (VCC) | Positive supply | Power rail for internal logic and output stage; decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Rev. H qualified | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces |
| 5.5 V tolerant inputs | Enables direct connection to 5 V or mixed-voltage subsystems without external clamping or translation |
| 3.7 ns typical tPD | Supports >200 MHz data rates in short trace configurations with 15 pF load |
| 2.0 µA max ICC | Reduces system standby power in battery-backed or energy-sensitive modules |
| TTL-compatible thresholds | VIL ≤ 0.8 V / VIH ≥ 2.0 V ensures interoperability with legacy 5 V microcontrollers and logic families |
Applications
| Automotive Body Control Module | Industrial PLC I/O Expansion |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | Wider VCC range (1.65–5.5 V); lower tPD (3.1 ns typ.); not AEC-Q100 qualified | Preferred for portable/battery-powered 3.3 V systems; unsuitable for automotive under-hood deployment | Select when operating below 4.5 V or requiring broader voltage flexibility; verify thermal derating for 125 °C ambient |
| 74AUP1G125GW,125 | Ultra-low ICC (0.9 µA max); slower tPD (6.4 ns typ.); -40 to +125 °C rated but not AEC-Q100 certified | Better for always-on IoT nodes with multi-year battery life; insufficient for automotive functional safety validation | Choose for extreme low-power applications where speed <6 ns is acceptable; confirm EMC performance matches TC7SET125F,LJ(CT in target layout |
Compared with SN74LVC1G125DBVR and 74AUP1G125GW,125, the TC7SET125F,LJ(CT uniquely combines AEC-Q100 Rev. H compliance, 5.5 V input tolerance, and sub-4 ns propagation delay - making it the only option qualified for automotive powertrain and chassis control signal buffering without additional qualification overhead.

FAQ
What is the maximum operating temperature range for the TC7SET125F,LJ(CT?
The TC7SET125F,LJ(CT is rated for -40 to +125 °C operation, validated per AEC-Q100 Rev. H requirements. This rating applies specifically to parts with ordering code ending in J(CT, as confirmed in Toshiba's Rev. 3.0.A datasheet Section 8 (Operating Ranges, Note 2).
Does the TC7SET125F,LJ(CT support 3.3 V logic inputs?
No - the TC7SET125F,LJ(CT is a 5 V-only device with VCC range 4.5–5.5 V. Its inputs are 5.5 V tolerant but require VIH ≥ 2.0 V and VIL ≤ 0.8 V; 3.3 V logic may not reliably meet VIH threshold under worst-case conditions and is outside specified operating ranges.
What is the pin configuration of the TC7SET125F,LJ(CT?
The TC7SET125F,LJ(CT uses SOT-25 (SMV) packaging with 5 pins: Pin 1 = G (active-low output enable), Pin 2 = A (input), Pin 3 = GND, Pin 4 = Y (3-state output), Pin 5 = VCC - as shown in Toshiba's datasheet Figure 4 (Pin Assignment, Top View).
Is the TC7SET125F,LJ(CT pin-compatible with other Toshiba TC7SET variants?
Yes - all TC7SET-series single-gate buffers in SOT-25 (SMV) package share identical pinout, including TC7SET00, TC7SET02, TC7SET04, and TC7SET125. Function differs per part number, but PCB layout and footprint are interchangeable.
What does the "J(CT" suffix indicate in TC7SET125F,LJ(CT?
The "J(CT" suffix denotes tape-and-reel packaging (CT) and the high-temperature grade (J) qualifying the device for -40 to +125 °C operation per AEC-Q100 Rev. H. This distinguishes it from standard-grade variants rated only to +85 °C.
