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