Product details
Overview
TC7SET126FU,LJ(CT) from Toshiba Electronic Devices & Storage Corporation is a single-bit 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°C to +125°C operating temperature, and draws only 2.0 µA max quiescent current.
For engineers reviewing the TC7SET126FU,LJ(CT) datasheet, TC7SET126FU,LJ(CT) pinout, TC7SET126FU,LJ(CT) application, or TC7SET126FU,LJ(CT) equivalent, key selection criteria include 3-state output control timing (tPZL/tPLZ), input voltage tolerance, AEC-Q100 qualification scope, and USV package thermal performance in space-constrained automotive modules.
Technical Context
The TC7SET126FU,LJ(CT) implements a non-inverting 3-state buffer with active-high output enable (G). Its logic function is defined by truth table entries where G = L forces high-impedance output (Z), while G = H passes A to Y. Input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) ensure robust interfacing with legacy TTL and mixed-voltage CMOS systems.
Designed for bus isolation in automotive control units, it features 5.5 V tolerant inputs independent of VCC (4.5–5.5 V), enabling safe level-shifting from higher-voltage sensors or microcontrollers. All DC and AC specifications-including tPLH/tPHL, tPZL/tPLZ, and IOZ leakage-are validated across -40°C to +125°C per AEC-Q100 Rev. H requirements for the (CT) variant.

FAQ
What is the maximum input voltage rating for TC7SET126FU,LJ(CT)?
The TC7SET126FU,LJ(CT) supports input voltages up to 5.5 V regardless of VCC level-a key feature enabling direct interfacing with 5 V peripherals without external level shifters. This rating is specified in Absolute Maximum Ratings and confirmed across all operating temperature ranges, including -40°C to +125°C.
Does TC7SET126FU,LJ(CT) meet AEC-Q100 requirements for automotive use?
Yes, the TC7SET126FU,LJ(CT) is explicitly qualified to AEC-Q100 Rev. H standards for Grade 1 operation (-40°C to +125°C). This includes stress testing for high-temperature operating life, temperature cycling, and ESD robustness-documented in Toshiba's reliability reports for this specific part number and (CT) suffix variant.
What is the typical propagation delay of TC7SET126FU,LJ(CT) under standard conditions?
The TC7SET126FU,LJ(CT) exhibits a typical propagation delay (tPLH/tPHL) of 3.7 ns when operated at VCC = 5.0 V ± 0.5 V with a 15 pF load. This value is measured at Ta = 25°C and is guaranteed to remain ≤ 6.0 ns across the full -40°C to +125°C operating range per AC Characteristics Table 9.4 and 9.6.
How does the 3-state output control work on TC7SET126FU,LJ(CT)?
The TC7SET126FU,LJ(CT) uses pin 2 (G) as an active-high output enable. When G = L, the output Y enters high-impedance (Z) state with leakage current ≤ ±0.25 µA. When G = H, Y follows input A with non-inverting logic. Truth table and timing parameters (tPZL/tPLZ) define precise enable/disable behavior critical for bus arbitration.
