FSTD16244

  The Fairchild Switch FSTD16244 provides 16-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 V_CC has been integrated into the circuit to allow for level shifting between 5V inputs and 3.3V outputs.

  The FSTD16244 is organized as a 16-bit switch. There are four 4-bit switches with separate output enable inputs. When OE is LOW, the switch in ON and Port A is connected to Port B. When OE is HIGH, the switch OFF and a high impedance state exists between the A and B Ports.
