853-2310 27452
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
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.

2. This is the increase in supply current for each input that is at the specified TTL voltage level rather than V
CC
or GND.
3. Measured by the voltage drop between the A and the B terminals at the indicated current through the switch. On-state resistance is
determined by the lower of the voltages of the two (A or B) terminals.

Short-form specification -- The data in a short-form specification is extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition -- Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 60134). Stress above one
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or
at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended
periods may affect device reliability.
