16-bit 1-of-2 multiplexer/demultiplexer with precharged
outputs and Schottky undershoot protection for live insertion

FEA TURES

•5 Ω typical r

on

•Pull-up on B ports

•Undershoot protection on A port only: –1.5 V

•Near zero propagation delay

•Controlled enable rate

•V

operating range: +4.5 V to +5.5 V

CC

•> 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 Ω channel resistance, and low I/O capacitance. A
port demultiplexes to either 1B and 2B, or to both. The switch is
bi-directional.

NOTES:

1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability .

2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.

3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
