Specifications subject to change without notice.
Temperature range as follows: K, L Versions = 0°C to +70°C; B, C Versions = –25°C to +85°C; T, U Versions = –55°C to +125°C.
Sample tested to ensure compliance.
DB0–DB11 = 0 V to V
Feedthrough can be further reduced by connecting the metal lid on the ceramic package to DGND.
Logic inputs are MOS gates. Typical input current (+25°C) is less than 1 nA.
