FST3245
Octal Bus Switch
General Description
The Fairchild Switch FST3245 provides 8-bits of high-
speed CMOS TTL-compatible bus switching in a standard
’245 pin-out. The low on resistance of the switch allows
inputs to be connected to outputs without adding propaga-
tion delay or generating additional ground bounce noise.
The device is organized as an 8-bit switch. When OE is
LOW, the switch is ON and Port A is connected to Port B.
When OE is HIGH, the switch is OPEN and a high-imped-
ance state exists between the two ports.
Features
s 4Ω switch connection between two ports.
s Minimal propagation delay through the switch.
s Low lCC.
s Zero bounce in flow-through mode.
s Control inputs compatible with TTL level.
