74FST3400
4−Bit, 4−Port Bus Exchange
Switch
The ON Semiconductor 74FST3400 is a 4−bit, 4−port bus exchange
switch. The device is CMOS TTL compatible when operating between
4.0 and 5.5 Volts. The device exhibits extremely low RON and adds
nearly zero propagation delay. The device adds no noise or ground
bounce to the system.
Features
RON 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 QS3400, FST3400, CBT3400
All Popular Packages: SOIC−24, TSSOP−24, QSOP−24
All Devices in Package TSSOP are Inherently Pb−Free*
