Product details
Overview
TC7SET126F,LJ(CT from Toshiba Electronic Devices & Storage Corporation is a single-channel 3-state bus buffer IC with TTL-compatible inputs, 5.5 V tolerant inputs, and AEC-Q100 qualified operation for automotive applications. It delivers 3.7 ns typical propagation delay at 5.0 V/15 pF, supports -40 to 85 °C operating temperature, and draws only 2.0 µA max quiescent current.
For engineers reviewing the TC7SET126F,LJ(CT datasheet, TC7SET126F,LJ(CT pinout, TC7SET126F,LJ(CT application, or TC7SET126F,LJ(CT equivalent, this page provides verified functional identity, validated pin assignment, confirmed automotive-grade thermal and reliability specs, and real-world interface use cases in CAN/LIN subsystems, sensor signal conditioning, and microcontroller I/O expansion.
Technical Context
The TC7SET126F,LJ(CT implements a non-inverting 3-state buffer with active-high output enable (G). Its input stage accepts TTL-level signals and tolerates up to 5.5 V regardless of VCC, enabling mixed-voltage interfacing. The output drives CMOS loads with VOH ≥ 4.4 V (min) at VCC = 4.5 V and IOL = 8 mA.
It operates within 4.5–5.5 V supply range and features high-impedance OFF-state leakage ≤ 0.1 µA at -40 to 85 °C. Propagation delay remains ≤ 6.9 ns (max) across full temperature and load conditions, supporting reliable timing in noise-sensitive automotive control modules.
Key Specifications

FAQ
What is the operating temperature range for TC7SET126F,LJ(CT?
The TC7SET126F,LJ(CT is rated for -40 to +85 °C operation, as confirmed by Toshiba's datasheet Note 2 and Operating Ranges section (Section 8). This range applies specifically to parts with the J(CT suffix and aligns with passenger compartment and under-dash ECU requirements.
Does TC7SET126F,LJ(CT support 3.3 V logic interfacing?
Yes - the TC7SET126F,LJ(CT accepts 3.3 V logic inputs reliably due to its VIH(min) = 2.0 V and VIL(max) = 0.8 V, which meet TTL thresholds. Its 5.5 V input tolerance further ensures compatibility with 3.3 V outputs even when VCC = 5.0 V, eliminating need for external level shifters.
Is TC7SET126F,LJ(CT pin-compatible with other TC7SET-series buffers?
No - the TC7SET126F,LJ(CT uses the SOT-25 (SMV) 5-pin package with unique pinout (A-G-GND-Y-VCC). Other TC7SET variants like TC7SET04 or TC7SET08 have different functions and pin assignments; direct substitution requires verification of both logic function and physical layout.
What is the maximum output drive capability of TC7SET126F,LJ(CT?
The TC7SET126F,LJ(CT delivers ±8 mA output current per channel, as specified in DC Characteristics Table 9.1 (IOL = 8 mA, IOH = -8 mA at VCC = 4.5 V). This supports driving multiple CMOS inputs or short PCB traces without external buffering.
How does the AEC-Q100 qualification of TC7SET126F,LJ(CT impact design validation?
The AEC-Q100 Rev. H qualification of TC7SET126F,LJ(CT means it has passed accelerated stress tests including HTOL, temperature cycling, and ESD - reducing need for redundant qualification at system level. Designers can rely on its documented failure rates and derating guidance from Toshiba's Reliability Handbook when deploying TC7SET126F,LJ(CT in automotive ECUs.
