FSTD16211 24-Bit Bus Switch with Level Shifting
General Description
The Fairchild Switch FSTD16211 provides 24-bits of highspeed CMOS TTL-patible 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. When OE1/2 is HIGH, a high impedance state exists between the A and B Ports.
Features s 4Ω switch connection between two ports. s Minimal propagation delay through the switch. s Low l CC. s Zero bounce in flow-through mode. s Control inputs patible with TTL level.
