FSTD16211

24-Bit Bus Switch with Level Shifting

General Description

The Fairchild Switch FSTD16211 provides 24-bits of high-

speed CMOS TTL-compatible bus switching. The low On

Resistance of the switch allows inputs to be connected to

outputs without adding propagation delay or generating

integrated into the circuit to allow for level shifting between

5V inputs and 3.3V outputs.

The device is organized as a 12-bit or 24-bit bus switch.

exists between the A and B Ports.
