FSTUD16211 24-Bit Bus Switch with −2V Undershoot Protection and Level Shifting
General Description
The Fairchild Switch FSTUD16211 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 additional ground bounce noise. A diode to VCC has been 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. When OE1 is LOW, the switch is ON and Port 1A is connected to Port 1B. When OE2 is LOW, Port 2A is connected to Port 2B.
