www.DataSheet4U.com HEF4952B 8-channel analog multiplexer/demultiplexer Rev. 01 — 20 March 2006 Product data sheet 1. General description The HEF4952B is a small signal switch providing a dual 5-channel analog multiplexer/demultiplexer with common select logic. Each multiplexer has four independent inputs/outputs (pins nY0 to nY3) and a common input/output (pin nZ). Via one channel, channel nY2 and nY3 can be connected to VSS. VSS and VDD are the supply voltage pins for the digital control inputs (pins A0 to A2). 2. Features s Schmitt-trigger action at control inputs s Small signal switch s Specified from −40 °C to +85 °C 3. Applications s Analog multiplexing and demultiplexing s Digital multiplexing and demultiplexing s Signal gating 4. Ordering information Table 1.
