Product details
Overview
TC7WH125FU,LJ(CT) from Toshiba Electronic Devices & Storage Corporation is a dual-channel CMOS bus buffer with 3-state outputs, designed for bidirectional data routing in low-voltage digital systems. It operates across 2.0–5.5 V supply, delivers 3.8 ns typical propagation delay at 5.0 V/15 pF, supports 5.5 V-tolerant inputs, and functions over –40°C to +125°C - ideal for automotive body control modules requiring robust signal isolation and voltage-level flexibility.
For engineers reviewing the TC7WH125FU,LJ(CT) datasheet, TC7WH125FU,LJ(CT) pinout, TC7WH125FU,LJ(CT) application, or TC7WH125FU,LJ(CT) equivalent, this page provides verified functional identity, temperature-grade validation (–40°C to +125°C), SM8 package mapping, confirmed 3-state dual-buffer architecture, and two validated alternative parts with documented electrical and thermal differences.
Technical Context
The TC7WH125FU,LJ(CT) implements two independent non-inverting buffers, each with active-low 3-state enable control (G1, G2), enabling bidirectional bus sharing without contention. Its input structure accepts voltages up to 5.5 V regardless of VCC, supporting mixed-voltage interfacing between 3.3 V and 5 V domains.
It features rail-to-rail output swing, low dynamic noise (VOLP ≤ 0.8 V max), and high noise immunity (VIH/VIL thresholds defined as 70%/30% of VCC), ensuring reliable operation in electrically noisy automotive and industrial environments where signal integrity is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Dual non-inverting 3-state bus buffer - enables time-multiplexed bidirectional data transfer on shared lines |
| Supply Voltage Range | 2.0 V to 5.5 V - supports direct interface with 2.5 V, 3.3 V, and 5 V logic families |
| Propagation Delay | 3.8 ns typ. at VCC = 5.0 V, CL = 15 pF - ensures sub-5 ns timing margin for 100 MHz bus cycles |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive applications per AEC-Q100 stress requirements |
| Input Tolerance | 5.5 V tolerant inputs - allows safe connection to higher-voltage peripherals without level shifters |
| Quiescent Current | 2.0 µA max at TA = 25°C - minimizes standby power in always-on vehicle subsystems |
| Output Drive | ±8 mA drive capability - sufficient to drive 15 pF loads across PCB traces and multiple gate inputs |
Pinout & Package
TC7WH125FU,LJ(CT) is housed in the SM8 package (JEDEC SOT-505), an 8-pin ultra-thin leadless plastic package measuring 2.0 × 2.5 mm with 0.5 mm pitch and 21 mg typical weight - optimized for space-constrained automotive ECUs and portable industrial controllers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G1) | Channel 1 Output Enable (active-low) | Asserting low enables Y1 output; high places Y1 in high-impedance state - isolates Channel 1 from bus |
| 2 (A1) | Channel 1 Input | Non-inverting input for first buffer; accepts 0–5.5 V signals independent of VCC |
| 3 (Y1) | Channel 1 Output | 3-state buffered output; drives bus when G1 = L, high-Z when G1 = H |
| 4 (GND) | Ground Reference | Common return path for all internal circuitry and I/O; must be low-impedance for noise suppression |
| 5 (Y2) | Channel 2 Output | 3-state buffered output; driven by A2 when G2 = L, high-Z otherwise |
| 6 (A2) | Channel 2 Input | Non-inverting input for second buffer; electrically identical to A1 |
| 7 (G2) | Channel 2 Output Enable (active-low) | Independent control of Y2; enables concurrent or staggered bus access for dual-channel arbitration |
| 8 (VCC) | Positive Supply | Power rail for internal logic and output drivers; decoupling capacitor required within 1 cm |
Key Features
| Feature | Design Value |
|---|---|
| Wide temperature range | –40°C to +125°C operation - meets automotive under-hood thermal requirements without derating |
| 5.5 V tolerant inputs | Eliminates need for external level translators when interfacing with legacy 5 V microcontrollers or sensors |
| Low dynamic noise | VOLP ≤ 0.8 V max - reduces crosstalk-induced glitches on adjacent high-speed signal lines |
| High noise immunity | VNIH/VNIL ≥ 28% VCC - rejects EMI transients common in motor-driven vehicle subsystems |
| Low quiescent current | ICC ≤ 2.0 µA max - extends battery life in always-on telematics and gateway modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G125DCKR | –40°C to +85°C rating; 3.3 V only VCC range (1.65–5.5 V); 3.7 ns tPD at 3.3 V | Not qualified for under-hood automotive use; suitable for consumer-grade portable instruments | Select when cost sensitivity outweighs extended temperature requirement and 5.5 V input tolerance is unnecessary |
| 74LVC2T45DP,122 | Bidirectional auto-direction sensing; no separate enable pins; 3.5 ns tPD at 3.3 V; same –40°C to +125°C range | Eliminates need for external direction-control logic but lacks independent channel enables | Select when bus arbitration uses automatic direction detection rather than explicit G1/G2 control signals |

The TC7WH125FU,LJ(CT) is rated for continuous operation from –40°C to +125°C, as confirmed in Section 2 (Features) and Section 8 (Operating Ranges) of its official datasheet. This specification applies specifically to devices with ordering part number ending in J(CT), distinguishing it from standard-grade variants limited to 85°C.
Does TC7WH125FU,LJ(CT) support 5 V inputs when powered from 3.3 V?
Yes, TC7WH125FU,LJ(CT) features 5.5 V tolerant inputs, meaning it safely accepts input voltages up to 5.5 V regardless of VCC setting (2.0–5.5 V). This capability is explicitly stated in Feature (5) and validated in Absolute Maximum Ratings (VIN = –0.5 to 7.0 V), enabling direct interfacing with 5 V peripherals without level-shifting circuitry.
What package type is used for TC7WH125FU,LJ(CT)?
TC7WH125FU,LJ(CT) uses the SM8 package, also known as JEDEC SOT-505 - an 8-pin, 2.0 × 2.5 mm leadless plastic package with 0.5 mm pitch and 21 mg typical weight. Package dimensions and mechanical data are provided on page 7 of the official Toshiba datasheet Rev.5.0.A.
How many independent 3-state buffers does TC7WH125FU,LJ(CT) contain?
The TC7WH125FU,LJ(CT) integrates two completely independent non-inverting 3-state buffers. Each has its own input (A1/A2), output (Y1/Y2), and active-low enable (G1/G2), allowing fully asynchronous control of bus access - confirmed in Functional Description, Truth Table, and Pin Assignment sections of the datasheet.
What is the typical propagation delay of TC7WH125FU,LJ(CT) at 5.0 V?
The typical propagation delay (tPLH/tPHL) of TC7WH125FU,LJ(CT) is 3.8 ns when operated at VCC = 5.0 V with CL = 15 pF, as specified in Feature (2) and AC Characteristics Table 9.4.
