74FST6800
10−Bit Bus Switch with
Precharged Outputs
The ON Semiconductor 74FST6800 is a 10−bit bus switch with
precharged outputs. The device is CMOS TTL compatible when
operating between 4.0 and 5.5 Volts. The device exhibits extremely
low R_ON and adds nearly zero propagation delay. The device adds no
noise or ground bounce to the system.
Features
• R_ON t 4 W Typical
• Less Than 0.25 ns−Max Delay Through Switch
• Nearly Zero Standby Current
• No Circuit Bounce
• Control Inputs are TTL/CMOS Compatible
• Pin−For−Pin Compatible With QS6800, FST6800, CBT6800
• All Popular Packages: SOIC−24, TSSOP−24, QSOP−24
• All Devices in Package TSSOP are Inherently Pb−Free*
