2 / 11 page Philips Semiconductors Product data CBT3257 Quad 1-of-2 multiplexer/demultiplexer 2 2002 Dec 13 FEATURES • 5 Ω switch connection between two ports • TTL-compatible input levels • Minimal propagation delay through the switch • Latch-up protection exceeds 500 mA per JESD78 • ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101 DESCRIPTION The CBT3257 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 B1 and B2 outputs for the A-input data. The CBT3257 is characterized for operation from -40 to +85 °C.
