10-Bit Low Power
Bus Exchange
The ON Semiconductor 74FST3383 is a 10−bit low power bus
exchange. The device is CMOS TTL compatible when operating
between 4 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
4 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 QS3383, FST3383, CBT3383
• All Popular Packages: SOIC−24, TSSOP−24, QSOP−24
• All Devices in Package TSSOP are Inherently Pb−Free*
