Product details
Overview
TC7SH125FU,LJ(CT from Toshiba Electronic Devices & Storage Corporation is a single-channel CMOS bus buffer with 3-state output, designed for signal routing and bus isolation in low-voltage digital systems. It operates from 2.0 V to 5.5 V, delivers 3.8 ns typical propagation delay at 5.0 V/15 pF, supports AEC-Q100 Grade 2 qualification, and features 5.5 V tolerant inputs - enabling interoperability with mixed-voltage logic domains in automotive body control modules.
For engineers reviewing the TC7SH125FU,LJ(CT datasheet, TC7SH125FU,LJ(CT pinout, TC7SH125FU,LJ(CT application, or TC7SH125FU,LJ(CT equivalent, key selection criteria include its -40 °C to 125 °C operating range, ultra-low 2.0 µA max ICC quiescent current, high noise immunity (28% VCC), and USV (SOT-353) 5-pin package for space-constrained PCB layouts.
Technical Context
The TC7SH125FU,LJ(CT implements a non-inverting 3-state buffer with active-high output enable (OE), where input signals pass through to the output only when OE is high; otherwise, the output enters high-impedance state. Its design targets bidirectional bus arbitration and load isolation in compact embedded systems requiring rail-to-rail input tolerance and minimal power overhead.
It uses Toshiba's advanced CMOS process to achieve simultaneous low static current (≤40 µA over full temperature range), fast switching (≤11.0 ns max tPLH/tPHL at -40 °C to 125 °C), and robust ESD protection - all within a 1.25 mm × 1.25 mm USV footprint compatible with automated SMT assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| 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 without level shifters. |
| Propagation Delay | 3.8 ns (typ.) at VCC = 5.0 V, CL = 15 pF - enables timing-critical data path buffering in sub-10 ns clock domains. |
| Quiescent Supply Current | 2.0 µA (max) at TA = 25 °C - reduces standby power in always-on automotive modules like door ECUs. |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Rev. H for under-hood and cabin electronics applications. |
| Input Voltage Tolerance | 5.5 V tolerant inputs - allows safe connection to higher-voltage peripherals without external clamping diodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | Same 5-pin SOT-23 package; slightly higher ICC (10 µA typ.); no AEC-Q100 qualification. | Limited to industrial/commercial temp range (-40 °C to +85 °C); not approved for automotive under-hood use. | Select when AEC-Q100 compliance is unnecessary and cost sensitivity outweighs extended temperature support. |
| 74LVC1G125GW,125 | SC-70-5 package (same footprint as USV); identical electrical specs but lower production volume and longer lead times. | Approved for automotive use per AEC-Q100 but lacks full traceability documentation for Tier-1 OEM programs. | Choose for prototyping or low-volume projects where supply chain flexibility is prioritized over full automotive audit readiness. |
Compared with SN74LVC1G125DBVR and 74LVC1G125GW,125, the TC7SH125FU,LJ(CT offers guaranteed AEC-Q100 Grade 2 qualification, tighter ICC max specification (2.0 µA vs. 10 µA), and documented 125 °C operation - making it the preferred choice for production automotive ECUs requiring long-term reliability and regulatory compliance.

FAQ
What is the maximum operating temperature for the TC7SH125FU,LJ(CT?
The TC7SH125FU,LJ(CT is rated for continuous operation from -40 °C to +125 °C, validated per AEC-Q100 Rev. H for automotive Grade 2 applications. This rating applies specifically to units with the "J(CT" suffix, distinguishing them from standard-temperature variants limited to 85 °C.
Does the TC7SH125FU,LJ(CT require external pull-up or pull-down resistors on its inputs?
No, the TC7SH125FU,LJ(CT does not require external biasing resistors on its inputs. Its VIH and VIL thresholds are internally defined as percentages of VCC (70% and 30%, respectively), and unused inputs must be tied to either VCC or GND per datasheet guidance to prevent floating states and ensure predictable 3-state behavior.
Can the TC7SH125FU,LJ(CT safely interface with 5 V logic while powered from a 3.3 V supply?
Yes, the TC7SH125FU,LJ(CT supports 5.5 V tolerant inputs, allowing direct connection of 5 V signals to pin 1 (A) and pin 5 (OE) even when VCC = 3.3 V. This eliminates level-shifting components and simplifies interconnection between legacy 5 V peripherals and modern 3.3 V microcontrollers.
What is the output drive capability of the TC7SH125FU,LJ(CT at 2.5 V supply?
At VCC = 2.5 V, the TC7SH125FU,LJ(CT delivers ±4 mA output drive (IOL/IOH) into resistive loads, sufficient to drive standard CMOS inputs and moderate capacitive loads up to ~20 pF. Full drive strength is specified down to 2.0 V, supporting ultra-low-voltage operation in energy-sensitive applications.
Is the TC7SH125FU,LJ(CT pin-compatible with other members of the TC7SH family?
No, the TC7SH125FU,LJ(CT is not universally pin-compatible across the TC7SH family. While it shares the USV 5-pin package with other single-gate variants (e.g., TC7SH00, TC7SH04), pin assignments differ by function - for example, TC7SH00 uses pin 1 as input A and pin 2 as input B, whereas TC7SH125FU,LJ(CT uses pin 2 as GND. Always verify pinout per device datasheet before substitution.
