74FST3861
10−Bit Bus Switch
The ON Semiconductor 74FST3861 is a 10−bit, high performance
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 QS3861, FST3861, CBT3861
• All Popular Packages: SOIC−24, TSSOP−24, QSOP−24
• All Devices in Package TSSOP are Inherently Pb−Free*
