CBT3126Quadruple FET bus switch

DESCRIPTION

The CBT3126 quadruple FET bus switch features independent line
switches. Each switch is disabled when the associated Output
Enable (OE) input is LOW.

FEATURES

•Standard ’126-type pinout (D, DB, and PW packages)

•5 Ω switch connection between two ports

•TTL-compatible input levels

•Latch-up testing is done to JESDEC Standard JESD78 which

exceeds 500 mA

•ESD protection exceeds 2000 V HBM per JESD22-A114,

200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101

NOTES:

1. Stresses beyond those listed under “absolute maximum ratings” 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 input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.

3. The package thermal impedance is calculated in accordance with JESD 51-7.
