FST3244WM - Fairchild Semiconductor

FST3244WM Octal Bus Switch

The Fairchild Switch FST3244 provides 8-bits of highspeed CMOS TTL-compatible bus switching in a standard ’244 pin-out. 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 two 4-bit switches with separate OE inputs. When OE is LO.
