12-bit 1-of-2 multiplexer/demultiplexer with internal pulldown resistors

FEA TURES

•6 Ω switch connection between two ports

•TTL compatible control input levels

•Break-before-make feature

•Internal 500 Ω pulldown resistors to ground

•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 CBT16292 is a 12-bit 1-of-2 high-speed TTL-compatible multiplexer/demultiplexer. The low on-state resistance of the switch of the switch allows connections to be made with minimal propagation delay.

When the select (S) input is low, port A is connected to port B1 and R

is connected to port B2. When S is high, port A is connected to

INT

port B2 and R The CBT162292 is characterized for operation from –40°C to +85°C.

is connected to port B1.

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 ju nction 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.
