The CBT3251 is a 1-of-8 high-speed TTL-compatible FET multiplexer/demultiplexer. The low on resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise.
The document describes the Philips CBT3251, an integrated circuit designed as a 1-of-8 high-speed TTL-compatible FET multiplexer/demultiplexer. Key features include minimal propagation delay through the switch and ESD protection exceeding 2000 V HBM per JESD22-A114.
The datasheet provides detailed information on absolute maximum ratings, recommended operating conditions (from -40 to +85 °C), DC electrical characteristics such as input clamp voltage and pass voltage, AC characteristics including propagation delay, pin configuration descriptions, logic diagrams, function tables, and mechanical outline dimensions for various package types including SOIC, SSOP, TSSOP, and QSOP.
