Product data
CBT3257
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.
