FEATURES

•5 Ω switch connection between two ports

•TTL-compatible input levels

•Schottky diodes on I/O clamp undershoot

•Minimal propagation delay through the switch

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

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

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

exceeds 100 mA

DESCRIPTION

The CBTS3253 is a dual 1-of-4 high-speed TTL-compatible FET
multiplexer/demultiplexer. The low on resistance of the switch allows
inputs to be connected to outputs without adding propagation delay
or generating additional ground bounce noise.

1OE

, 2OE, S0, and S1 select the appropriate B output for the

A-input data.
Internal Schottky diode provides I/O undershoot protection
The CBTS3253 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 51-7.

2. This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC 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 lowest voltage of the two (A or B) terminals.
