DESCRIPTION

The CBT6832D is a 16-bit controlled enable rate 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: –2.0 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-X hot-plugging
