DESCRIPTION
The CBT6832 is a 16-bit 1-of-2 multiplexer/demultiplexer with precharged outputs and charge pump undershoot protection for live insertion. Advantages of the CBT6832 include a propagation delay of 250 ps, resulting from 5 Ω channel resistance, and low I/O capacitance. A port demultiplexes to either 1B and 2B, or to both. The switch is bi-directional.

FEATURES
• 5 Ω typical ron
• Pull-up on B port
• Undershoot protection on A port only: –1.5 V
• Near zero propagation delay
• Controlled enable rate
• VCC operating range: +4.5 V to +5.5 V
• > 100 MHz bandwidth (or clock rate) at 20 pF load capacitance
• 56-pin TSSOP package
• Bias voltage pre-charges the B output when the channel is disabled
• Latch-up protection exceeds 100 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

APPLICATION
• Provides PCI hot-plugging
