Product details
Overview
TC7SH126F,LJ(CT) from Toshiba Electronic Devices & Storage Corporation is a single-channel CMOS bus buffer with 3-state output, designed for bidirectional data path control in low-voltage digital systems. It operates across VCC = 2.0–5.5 V, delivers tPD = 3.8 ns (typ.) at 5.0 V/15 pF, and supports automotive-grade reliability per AEC-Q100 Rev. H - used in engine control unit signal conditioning and CAN transceiver interface buffering.
For engineers reviewing the TC7SH126F,LJ(CT) datasheet, TC7SH126F,LJ(CT) pinout, TC7SH126F,LJ(CT) application, or TC7SH126F,LJ(CT) equivalent, key selection criteria include its -40 to 85 °C operating range (per J(CT suffix), 5.5 V tolerant inputs, sub-2 µA quiescent current, and SOT-25 (SMV) package compatibility with space-constrained PCB layouts.
Technical Context
The TC7SH126F,LJ(CT) implements a non-inverting 3-state buffer with active-high output enable (G). Its logic function enables/disables signal pass-through between input A and output Y, placing Y in high-impedance state when G = L - critical for shared-bus arbitration. Input thresholds are ratio-based (VIH ≥ 0.7×VCC, VIL ≤ 0.3×VCC), ensuring noise immunity of ≥28% VCC.
It features rail-to-rail output swing, 5.5 V tolerant inputs independent of VCC, and guaranteed DC performance over -40 to 85 °C. AC timing includes tPZL/tPZH ≤ 5.5 ns and tPLZ/tPHZ ≤ 7.1 ns (5.0 V, CL = 15 pF), supporting reliable operation in 25 MHz+ digital interfaces with controlled rise/fall times.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0–5.5 V - supports mixed-voltage system interfacing (e.g., 3.3 V MCU to 5 V peripheral) |
| tpd (max) | 5.5 ns @ 5.0 V, CL = 15 pF - enables reliable timing in 180+ MHz data strobes |
| ICC (max) | 20.0 µA @ Ta = -40 to 85 °C - ensures ultra-low static power in always-on automotive modules |
| Input Tolerance | 5.5 V absolute max on inputs - allows safe interfacing with higher-voltage logic without level shifters |
| Operating Temp | -40 to +85 °C - qualified for passenger compartment electronics (non-engine bay) |
| IOZ (max) | ±0.25 µA @ VOUT = VCC/GND - guarantees minimal leakage during 3-state hold in battery-powered sleep modes |
| VNIH/VNIL | ≥28% VCC - provides robust noise margin against EMI in automotive harness environments |
Pinout & Package
TC7SH126F,LJ(CT) uses the JEDEC-standard SOT-25 (SMV) package: 5-pin, surface-mount, 1.6 × 2.8 × 1.1 mm, 14 mg typical weight. Pin 1 marked via dot; top-view orientation follows standard semiconductor convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Buffer Input | Non-inverting data input; accepts 0–5.5 V signals regardless of VCC level |
| 2 (G) | Output Enable | Active-high control: G = H enables Y = A; G = L forces Y into high-impedance state |
| 3 (GND) | Ground Reference | Primary return path for supply and signal currents; must be low-impedance connection |
| 4 (Y) | Buffer Output | 3-state output with rail-to-rail swing; drives up to ±8 mA (VOL ≤ 0.1 V @ IOL = 4 mA) |
| 5 (VCC) | Supply Voltage | Power rail for internal logic; decoupling capacitor (0.1 µF) required within 3 mm of this pin |
Key Features
| Feature | Design Value |

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 SOT-25 package; wider temp range (-40 to 125 °C); slightly higher ICC (10 µA max) | Preferred for engine bay applications requiring extended temperature rating | Select SN74LVC1G125DBVR only if 125 °C operation is mandatory; otherwise TC7SH126F,LJ(CT) offers lower standby current and AEC-Q100 documentation traceability |
| 74LVC1G126GW,125 | NXP part in SC-70-5; identical logic function; 3.6 V max VCC (no 5.5 V tolerance) | Not suitable for mixed 5 V/3.3 V systems due to input voltage limitation | Choose 74LVC1G126GW,125 only in pure 3.3 V designs where footprint compatibility is secondary to cost |
Compared with SN74LVC1G125DBVR and 74LVC1G126GW,125, the TC7SH126F,LJ(CT) uniquely combines AEC-Q100 Rev. H certification, 5.5 V input tolerance, and sub-20 µA max ICC at 85 °C - making it optimal for cost-sensitive, thermally constrained automotive body electronics where reliability documentation and low-power sleep modes are prioritized.
