Mingjiada Electronics: Specializing in Supply and Procurement—Aerospace-Grade Radiation-Hardened NAND Gate ICs for Aerospace and Low Earth Orbit Applications: LEOAC00PT-D

LEOAC00PT-D Product Overview

In the design of aerospace and high-reliability electronic systems, the radiation hardiness and reliability of logic devices are of critical importance. The LEOAC00PT-D is a radiation-hardened, plastic-encapsulated, four-channel, 2-input NAND gate developed by STMicroelectronics, specifically designed for Low Earth Orbit (LEO) space applications.

Manufactured using an advanced CMOS process, this device delivers stable logic functionality while maintaining low power consumption, making it a core building block for signal processing and control logic in aerospace electronic systems. Mingjiada Electronics maintains a long-term supply of genuine, in-stock LEOAC00PT-D devices and actively sources this model globally to provide customers with comprehensive supply chain support.

Technical Specifications and Features

The LEOAC00PT-D integrates four independent 2-input NAND gates in a compact TSSOP-20 package. Its key technical specifications are as follows:

Manufacturer: STMicroelectronics

Package Type: TSSOP-20 (Thin Shrink Small Outline Package)

Operating Voltage: 2V ~ 6V

Absolute Maximum Voltage: 7V

Propagation Delay: 8 ns @ 4.5V, 50 pF

Output Current: ±24 mA (High/Low)

Quiescent Current (Max) 40 µA

Operating Temperature Range -40°C to +125°C

Logic Level - Low 0.9 V to 1.65 V

Logic Level - High 2.1 V to 3.85 V

Radiation Resistance

The core advantage of the LEOAC00PT-D lies in its radiation resistance, which has been specifically optimized for space environments:

Total Ionizing Dose (TID): 50 krad(Si), capable of withstanding the cumulative radiation dose in low Earth orbit

Single-Event Latch-Up Immunity (SEL-free): LET resistance up to 62.5 MeV·cm²/mg, effectively preventing device latch-up caused by single-event effects

Low Outgassing Characteristics: RML <1%, CVCM <0.1%, meeting the stringent outgassing requirements for spacecraft materials

Anti-Whisker Design: Features nickel/palladium/gold (NiPdAu) lead plating and gold wire bonding to prevent short-circuit risks caused by tin whisker growth
