CBT3257A Quad 1-of-2 multiplexer/demultiplexer Rev. 04 -- 19 March 2009 Product data sheet 1. General description The CBT3257A is a quad 1-of-2 high-speed TTL-compatible 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. Output enable (OE) and select-control (S) inputs select the appropriate nB1 and nB2 outputs for the nA input data. The CBT3257A is characterized for operation from -40 C to +85 C. 2. Features 5 switch connection between two ports TTL-compatible input levels Minimal propagation delay through the switch Latch-up protection exceeds 500 mA per JEDEC standard JESD78 class II level A ESD protection: u HBM JESD22-A114E exceeds 2000 V u MM JESD22-A115-A exceeds 200 V u CDM JESD22-C101C exceeds 1000 V n Multiple package options n Specified from -40 C to +85 C n n n n n 3.
