16-Bit Bus Switch
General Description
The Fairchild Switch FST16245 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.
The device is organized as a 16-bit switch. There are two
8-bit switches with separate output enable inputs. When
OE is LOW, the switch is ON and Port a is connected to
Port B. When OE is HIGH, the switch is OFF and a high
impedance state exists between the A and B Ports.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
