The FST3244 is an 8-bit bus switch with features such as 4Ω switch connection, minimal propagation delay, low ICC, and zero bounce in flow-through mode.
The FST3244 is an 8-bit bus switch organized as two four-bit switches with separate /OE inputs. It provides high-speed, CMOS, TTL-compatible bus switching in a standard '244 pin-out. The device features low on-resistance, allowing inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. It operates in a flow-through mode where the switch is ON when /OE is LOW, connecting Port A to Port B, and OPEN (high-impedance) when /OE is HIGH.
