With the explosive growth of the global commercial space industry and low Earth orbit (LEO) satellite constellations, the demand for radiation-hardened, highly reliable aerospace-grade components is becoming increasingly urgent. As a seasoned player in the electronic components supply chain, Shenzhen Mingjiada Electronics Co., Ltd. now supplies and purchases STMicroelectronics’ flagship radiation-hardened product—the LEOAC14PT-D—globally. This article will provide a detailed overview of the features of this chip, which is specifically designed for harsh space environments, and explain how Mingjiada offers you a one-stop service ranging from supply to inventory buyback.
Core Product Overview: Radiation-Hardened Six-Inverter Designed for LEO Satellites
The LEOAC14PT-D is a radiation-hardened, plastic-packaged six-inverter device launched by STMicroelectronics. Its core advantage lies in the integration of Schmitt trigger inputs, which can condition slowly changing or noise-affected input signals into clear, steep-rising output signals—a critical feature for signal integrity in satellite attitude control, onboard computers, and communication payloads.
This device strictly adheres to the ST-LEO specification—a quality assurance system based on the AEC-Q100 standard and tailored specifically for space applications. While ensuring radiation resistance, it significantly reduces the bill of materials (BOM) cost and footprint for space projects. Its specific technical parameters are shown in the table below:
Key Parameters
Logic Function: Six-inverter (with Schmitt trigger inputs)
Operating Voltage: 2 V to 6 V (Absolute Maximum: 7 V)
Radiation Tolerance (TID): 50 krad (Si) Total Ionizing Dose
Single-Event Locking (SEL): Immune up to 62.5 MeV·cm²/mg
Operating Temperature: -40°C to +125°C (Meets extreme temperature ranges in space)
Package Type: Plastic TSSOP-20 (Thin Shrink Small Outline Package)
Special Process: Gold wire bonding + NiPdAu plating (whisker-resistant, high reliability)
Weight: Only 80 mg (lightweight design)
Applications: Where is interference immunity and high reliability required?
The LEOAC14PT-D is not only suitable for low Earth orbit (LEO) satellite platforms; its AEC-Q100 automotive-grade certification also enables it to perform exceptionally well in high-reliability ground equipment:
Satellite platforms and payloads: Serves as the digital logic interface for on-board computers, processing slowly changing signals from attitude sensors (such as star trackers and sun sensors).
Space Power Management: Used in power control units to generate clean enable signals and status indications.
Aerospace-Grade Communication Systems: Ensures digital signal integrity between the RF front end and the baseband processing unit.
Automotive and High-End Industrial Applications: Suitable for autonomous driving domain controllers requiring electromagnetic interference (EMI) immunity or harsh industrial environments.
