Product details
Overview
TC7SZ07FU,LJ(CT from Toshiba Electronic Devices & Storage Corporation is a single-channel CMOS non-inverting buffer with open-drain output, designed for level-shifting and wired-OR logic applications in automotive and industrial systems. It operates from 1.65 V to 5.5 V, delivers ±24 mA output drive at 3.0 V, achieves 2.3 ns typical propagation delay at 5.0 V/50 pF, and supports AEC-Q100 Grade 1 qualification (–40 °C to +125 °C).
For engineers reviewing the TC7SZ07FU,LJ(CT datasheet, TC7SZ07FU,LJ(CT pinout, TC7SZ07FU,LJ(CT application, or TC7SZ07FU,LJ(CT equivalent, this device is selected for high-speed open-drain interface design requiring 5.5 V-tolerant inputs, power-down protection, and robust operation across extended temperature ranges in automotive body control modules and industrial I/O subsystems.
Technical Context
The TC7SZ07FU,LJ(CT implements a single-stage CMOS non-inverter with open-drain N-channel MOSFET output, enabling pull-up–based logic combining and voltage-level translation between disparate supply domains. Its input structure tolerates up to 5.5 V regardless of VCC, and its output remains high-impedance during power-down to prevent back-driving.
It features active-low 3-state control via input logic state only - no separate enable pin - and maintains <±10 µA input leakage over –40 °C to +85 °C and <±20 µA up to +125 °C. The device matches TC74LCX-series AC performance at 3.3 V while supporting broader VCC range and enhanced thermal reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Single non-inverting buffer with open-drain output - enables wired-OR bus structures and level translation without external logic. |
| Supply Voltage Range | 1.65 V to 5.5 V - supports mixed-voltage system interfacing (e.g., 1.8 V MCU driving 5 V bus). |
| Input Voltage Tolerance | –0.5 V to 6.0 V - allows safe connection to higher-voltage signals without clamping diodes or level shifters. |
| Output Drive Strength | ±24 mA min at VCC = 3.0 V - drives standard TTL loads and multiple CMOS inputs directly. |
| Propagation Delay | 2.3 ns typ. at VCC = 5.0 V, CL = 50 pF - enables use in sub-200 MHz digital timing paths. |
| Operating Temperature | –40 °C to +125 °C - qualified per AEC-Q100 Rev. H for under-hood automotive applications. |
| Power-Down Protection | 5.5 V tolerant output in high-impedance state - prevents current injection during VCC ramp-down or loss. |
Pinout & Package
TC7SZ07FU,LJ(CT is housed in a 5-pin USV package (JEDEC SOT-353), measuring 2.0 × 1.25 × 0.9 mm with 0.65 mm lead pitch. The package is halogen-free, RoHS-compliant, and optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (A) | CMOS-compatible digital input; accepts 0–5.5 V logic levels independent of VCC. |
| 2 | GND | Ground reference for all internal circuitry and output discharge path. |
| 3 | Output (Y) | Open-drain N-channel output; requires external pull-up to define high level and sink current. |
| 4 | VCC | Positive supply rail (1.65–5.5 V); powers internal logic and defines output low threshold. |
| 5 | N/C | No internal connection - left unconnected; not electrically tied to any internal node. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 compliance | Validated for automotive use at –40 °C to +125 °C ambient, including temperature cycling and HTOL stress. |
| 5.5 V-tolerant inputs | Enables direct interface to legacy 5 V logic or sensor outputs without level-shifting circuitry. |
| High-speed propagation | 2.3 ns typical tPZL at 5 V ensures minimal timing skew in clock distribution or data strobe paths. |
| Power-down output isolation | Output enters high-Z state when VCC = 0 V, preventing back-current into powered subsystems. |
| Low quiescent current | ICC ≤ 1 µA max at VCC = 5.5 V - suitable for always-on monitoring circuits with battery backup. |
Applications
| Automotive Body Control Unit | Industrial Digital I/O Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DBVR | Same SOT-23-5 package; 1.65–5.5 V VCC; 32 mA sink at 3.3 V; AEC-Q100 not specified. | Rated for –40 °C to +125 °C but lacks formal AEC-Q100 certification; lower propagation delay (1.5 ns typ. at 3.3 V). | Select when AEC-Q100 is not required and higher sink current or faster speed is prioritized. |
| 74AUP1G07GW,125 | Smaller XSON-6 package; 0.8–3.6 V VCC only; 4 mA sink at 3.0 V; ultra-low ICC (0.1 µA max). | Not suitable for 5 V systems or automotive under-hood use; optimized for battery-powered portable devices. | Select for space-constrained, low-power 1.8/3.3 V applications where 5 V tolerance and high drive are unnecessary. |
Compared with SN74LVC1G07DBVR and 74AUP1G07GW,125, the TC7SZ07FU,LJ(CT uniquely combines AEC-Q100 Grade 1 qualification, 5.5 V input tolerance, and ±24 mA drive in a USV package - making it the only choice for automotive-grade open-drain buffering where voltage interoperability and thermal robustness are mandatory.

FAQ
What is the maximum operating temperature for TC7SZ07FU,LJ(CT?
The TC7SZ07FU,LJ(CT is rated for operation from –40 °C to +125 °C and is AEC-Q100 Rev. H Grade 1 qualified. This rating applies specifically to devices with ordering part number ending in "J(CT", as confirmed in the manufacturer's datasheet revision 2.0.B.
Does TC7SZ07FU,LJ(CT support 5 V logic inputs while powered from 1.8 V?
Yes, TC7SZ07FU,LJ(CT supports 5.5 V-tolerant inputs regardless of VCC voltage. When powered from 1.8 V, it safely accepts 0–5.5 V input signals - a key feature enabling level translation without external components.
What is the output configuration of TC7SZ07FU,LJ(CT and how should it be used?
The TC7SZ07FU,LJ(CT has an open-drain N-channel output (pin 3) that sinks current only. It requires an external pull-up resistor to define the high logic level. This configuration supports wired-OR bus architectures and bidirectional signal conditioning in I²C-like interfaces.
Is TC7SZ07FU,LJ(CT pin-compatible with other TC7SZ-series buffers?
No - TC7SZ07FU,LJ(CT uses a 5-pin USV (SOT-353) package with pin 5 designated N/C. Other TC7SZ variants like TC7SZ14 (Schmitt-trigger inverter) or TC7SZ17 (buffer with Schmitt input) share the same footprint but differ in function and internal topology; pin compatibility does not imply functional interchangeability.
What is the minimum supply voltage required for TC7SZ07FU,LJ(CT to meet its specified output drive?
The TC7SZ07FU,LJ(CT guarantees ±24 mA output sink/source capability at VCC = 3.0 V. At lower voltages (e.g., 1.8 V), output drive drops to ≥4 mA (IOL = 4 mA typ.), as specified in DC characteristics tables for VCC = 1.65–1.95 V range.
