Product details
Overview
TC7WZ125FK,LJ(CT) from Toshiba Electronic Devices & Storage Corporation is a dual-channel CMOS bus buffer with 3-state outputs, designed for high-speed bidirectional data routing in low-voltage digital systems. It operates across 1.65–5.5 V supply, delivers ±24 mA output drive at 3.0 V, achieves 2.6 ns typical propagation delay at 5.0 V/50 pF, and supports automotive-grade temperature range (−40 to +125 °C) per AEC-Q100 Rev. H.
For engineers reviewing the TC7WZ125FK,LJ(CT) datasheet, TC7WZ125FK,LJ(CT) pinout, TC7WZ125FK,LJ(CT) application, or TC7WZ125FK,LJ(CT) equivalent, this device is selected for level-shifting I/O expansion, hot-swap-capable bus isolation, and noise-immune signal buffering where 5.5 V-tolerant inputs and power-down protection are required.
Technical Context
The TC7WZ125FK,LJ(CT) integrates two independent non-inverting buffers, each with active-low 3-state enable control (G), enabling precise bus arbitration and dynamic load management. Its input structure accepts 5.5 V logic regardless of VCC, while its output stage provides 5.5 V power-down protection-ensuring safe high-impedance state during VCC = 0 V conditions.
This device implements ultra-high-speed TTL-compatible switching with tPLH/tPHL ≤ 2.6 ns (typ.) at 5.0 V and CL = 50 pF, and maintains consistent timing performance across 1.65–5.5 V operation. Its design targets compatibility with TC74LCX-series timing at 3.3 V while extending voltage range and thermal robustness for automotive and industrial control subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.65–5.5 V - enables single-supply interoperability across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains. |
| Propagation Delay | 2.6 ns (typ.) at VCC = 5.0 V, CL = 50 pF - supports >300 MHz data rates in short-bus configurations. |
| Output Drive | ±24 mA (min.) at VCC = 3.0 V - drives 50 Ω transmission lines or multiple CMOS loads without external buffering. |
| Input Tolerance | 5.5 V tolerant - allows interfacing with higher-voltage peripherals without level shifters. |
| Operating Temp | −40 to +125 °C - qualified per AEC-Q100 Rev. H for under-hood automotive ECUs and industrial motor controllers. |
| Power-Down Protection | 5.5 V output protection at VCC = 0 V - prevents back-driving and latch-up during power sequencing. |
| 3-State Leakage | ≤0.1 µA (max.) at VCC = 5.5 V - minimizes standby current in multiplexed bus architectures. |
Pinout & Package
TC7WZ125FK,LJ(CT) uses the US8 (JEDEC SOT-765) 8-pin ultra-thin shrink small-outline package (2.1 × 2.0 × 0.55 mm), optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Channel 1 Input | Non-inverting data input for first buffer; 5.5 V tolerant, compatible with mixed-voltage signaling. |
| 2 (G1) | Channel 1 Output Enable (Active Low) | Asserting low enables Y1 output; high forces Y1 into high-impedance state for bus sharing. |
| 3 (Y1) | Channel 1 Output | 3-state buffered output with ±24 mA drive capability and 5.5 V power-down protection. |
| 4 (GND) | Ground | Reference return path for all signals and supply currents; must be low-inductance connection. |
| 5 (Y2) | Channel 2 Output | Independent 3-state output mirroring Y1 functionality; electrically isolated from Y1. |
| 6 (G2) | Channel 2 Output Enable (Active Low) | Separate control for second buffer; enables independent channel gating without cross-talk. |
| 7 (A2) | Channel 2 Input | Second non-inverting input; identical electrical specs to A1, supporting dual-bus topology. |
| 8 (VCC) | Positive Supply | Single supply rail powering both channels; decoupling capacitor required within 1 cm. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified | Meets Rev. H stress test requirements for automotive electronics, including temperature cycling and HTOL. |
| Wide VCC range | Operates from 1.65 V to 5.5 V - eliminates need for separate voltage translators in multi-rail systems. |
| 5.5 V-tolerant inputs | Accepts 0–5.5 V input signals regardless of VCC setting - simplifies interface to legacy 5 V peripherals. |
| Power-down protection | Outputs remain high-impedance and non-destructive when VCC = 0 V - prevents back-powering downstream circuits. |
| Ultra-fast propagation | 2.6 ns typical tPD at 5 V enables use in DDR clock distribution, FPGA I/O expansion, and real-time control loops. |
| Low quiescent current | ICC ≤ 1 µA (max.) at VCC = 5.5 V - reduces system-level standby power in always-on 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 |
|---|---|---|---|
| SN74LVC2G125DPWR | Lower max VCC (3.6 V), no AEC-Q100 qualification, 3.7 ns tPD at 3.3 V. | Restricted to commercial-temp industrial or consumer gear; unsuitable for under-hood automotive use. | Select when cost sensitivity outweighs automotive qualification and 5 V tolerance is unnecessary. |
| 74AUP2G125GW,125 | Wider temp range (−40 to +125 °C), but only 1.8–3.6 V VCC, 3.8 ns tPD at 3.3 V, no 5.5 V input tolerance. | Applicable in battery-powered IoT edge nodes requiring ultra-low ICC (0.5 µA typ.), but not for mixed-voltage bus bridging. | Prefer for energy-constrained portable devices where 5 V interface compatibility is absent. |

FAQ
What is the maximum operating temperature range for TC7WZ125FK,LJ(CT)?
The TC7WZ125FK,LJ(CT) is rated for −40 to +125 °C operation and qualified per AEC-Q100 Rev. H, making it suitable for under-hood automotive environments and high-temperature industrial enclosures. This rating applies specifically to the J(CT suffix variant, as confirmed in Section 2 Note 2 and Section 8 of the datasheet.
Does TC7WZ125FK,LJ(CT) support 5 V logic inputs when powered from 3.3 V?
Yes, TC7WZ125FK,LJ(CT) features 5.5 V-tolerant inputs, allowing it to accept 0–5.5 V signals regardless of VCC setting-including when VCC = 3.3 V. This eliminates external level shifters in mixed-voltage systems, as explicitly stated in Feature (6) of the datasheet.
What is the typical propagation delay of TC7WZ125FK,LJ(CT) at 3.3 V supply?
At VCC = 3.3 V and CL = 50 pF, the typical propagation delay (tPLH/tPHL) of TC7WZ125FK,LJ(CT) is 2.9 ns, as specified in Table 9.4 AC Characteristics (VCC = 3.3 ± 0.3 V row, Typ. column). This value is measured under standard load and input transition conditions defined in Section 9.7.
How does the power-down protection feature work in TC7WZ125FK,LJ(CT)?
TC7WZ125FK,LJ(CT) provides 5.5 V power-down protection on outputs: when VCC = 0 V, the outputs remain in high-impedance state and tolerate up to 5.5 V without damage or back-current flow. This behavior is guaranteed per Absolute Maximum Ratings (Section 7) and Operating Ranges (Section 8 Note 2).
Is TC7WZ125FK,LJ(CT) pin-compatible with other Toshiba dual buffer variants like TC7WZ07?
No, TC7WZ125FK,LJ(CT) is not pin-compatible with TC7WZ07. The TC7WZ125FK,LJ(CT) uses an active-low 3-state enable (G) per channel and non-inverting logic, whereas TC7WZ07 is a dual non-inverting buffer without 3-state control. Pin assignments differ fundamentally-confirmed by comparing Section 4 Pin Assignment and functional descriptions in respective datasheets.
