FUNCTION

CBTS3306Dual bus switch with Schottky diode clamping

FEA TURES

•5 Ω switch connection between two ports

•TTL-compatible input levels

•Package options include plastic small outline (SO) and

thin shrink small outline (TSSOP)

•Latch-up protection exceeds 100 mA per JESD78

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

1000 V CDM per JESD22-C101

DESCRIPTION

The CBTS3306 Dual FET Bus Switch features independent line
switches with Schottky diodes on the I/OS to clamp undershoot.
Each switch is disabled with the associated Output Enable (OE
input is high.

The CBTS3306 is characterized for operation from –40 to +85 °C.

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 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.
