74FST3384
10−Bit Low Power
Bus Switch
The ON Semiconductor 74FST3384 is a 10−bit low power bus
switch. 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 QS3384, FST3384, CBT3384
• All Popular Packages: SOIC−24, TSSOP−24, QSOP−24
• All Devices in Package TSSOP are Inherently Pb−Free*
