37916

The Fairchild Switch 37916 provides 20-bits of highspeed 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 37916 is organized as a 10-bit or 20-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 OEX is HIGH, a high impedance state exists between the A and B Ports. The FSTD162861 has equivalent 25 series resistors to reduce signal-reflection noise, eliminating the need for external terminating resistors.
