ATIC55D5-3 High-Reliability 5V CMOS Inverter for Airbag ECU, Radiation-Tolerant Automotive Power IC
The ATIC55D5-3 is a high-reliability, radiation-hardened 5V CMOS inverter specifically engineered for critical automotive safety systems, particularly airbag electronic control units (ECUs) and communication power management modules.
This device operates within a standard supply voltage range of 4.5V to 5.5V, ensuring seamless integration into existing 5V automotive architectures.
With a typical propagation delay of just 7 nanoseconds, it delivers the high-speed signal processing essential for real-time crash detection and airbag deployment timing.
The ATIC55D5-3 is built to withstand extreme environmental conditions, featuring an ambient operating temperature range spanning from -55°C to +125°C, making it suitable for both under-hood and cabin safety applications.
Its robust design includes a remarkable total ionizing dose (TID) radiation tolerance of up to 100 krad(Si), ensuring consistent performance even in high-reliability scenarios.
The chip offers a maximum power dissipation of 1000 mW and provides a minimum output high current of -4 mA and output low current of 4 mA, supporting direct interfacing with various automotive microcontrollers and logic circuits.
ESD protection is rated at 2000V (Human Body Model), providing enhanced durability during manufacturing and assembly processes.
This component is ideal for designers seeking a reliable, high-speed inverting buffer solution for automotive safety systems, powertrain control, and industrial applications where voltage level shifting and signal integrity are critical.
The ATIC55D5-3 comes in a standard Ceramic DIP-8 package and maintains strict input leakage current limits of ±1 μA to ensure system power efficiency.
Its wide storage temperature range (-65°C to +150°C) further guarantees long-term reliability under harsh logistics and operational environments.
