The is a quad 1-of-2 high-speed TTL-compatible multiplexer/demultiplexer. The low ON-state 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 to +85 �C.
5 switch connection between two ports TTL-compatible input levels Minimal propagation delay through the switch ESD protection exceeds 2000 V HBM per V MM per JESD22-A115 and 1000 V CDM per JESD22-C101 s Latch-up testing is done to JEDEC standard JESD78 which exceeds 100 mA
