CM1234-08DE Description

Short technical summary and product information.

The CM1234-08DE from On Semiconductor is an 8-channel ESD clamp array designed for protecting high-speed data lines such as HDMI and DVI ports. It provides ESD protection per IEC 61000-4-2 Level 4 with ±15 kV contact discharge and ±20 kV air discharge. Each I/O pin can withstand over 1000 ESD strikes at ±8 kV contact.

 

The device features a pass-through impedance matched clamp architecture with 100 Ω differential impedance per paired channel and channel-to-channel matching of 2% maximum deviation. This ensures minimal signal skew and high signal integrity for high-speed interfaces.

 

The CM1234-08DE is housed in a 16-WDFN exposed pad package (6x4 mm) and supports surface mount assembly. It operates over a temperature range of -40°C to 85°C. The device is RoHS compliant and lead-free.
