SN74CBT16214C
12BIT 1OF3 FET MULTIPLEXER/DEMULTIPLEXER
5V BUS SWITCH WITH 2V UNDERSHOOT PROTECTION

POST OFFICE BOX 655303
DALLAS, TEXAS 75265
description/ordering information (continued)
The SN74CBT16214C is a high-speed TTL-compatible FET multiplexer/demultiplexer with low ON-state
resistance (ron), allowing for minimal propagation delay. Active Undershoot-Protection Circuitry on the A and
B ports of the SN74CBT16214C provides protection for undershoot up to 2 V by sensing an undershoot event
and ensuring that the switch remains in the proper OFF state.
The SN74CBT16214C is a 12-bit 1-of-3 multiplexer/demultiplexer. The select (S0, S1, S2) inputs control the
data path of each multiplexer/demultiplexer. When the multiplexer/demultiplexer is enabled, the A port is
connected to the B port, allowing bidirectional data flow between ports. When the multiplexer/demultiplexer is
disabled, a high-impedance state exists between the A and B ports.
This device is fully specified for partial-power-down applications using Ioff. The Ioff feature ensures that
damaging current will not backflow through the device when it is powered down. The device has isolation during
power off.
To ensure the high-impedance state during power up or power down, each select input should be tied to GND
through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability
of the driver.
