74FST3253
Dual 4:1 Multiplexer/
Demultiplexer Bus Switch
The ON Semiconductor 74FST3253 is a dual 4:1, high performance
multiplexer/demultiplexer bus switch. The device is CMOS TTL
compatible when operating between 4 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 QS3253, FST3253, CBT3253
All Popular Packages: QSOP−16, TSSOP−16, SOIC−16
