Product Summary

The FST3253MTCX is a dual 4:1 high-speed CMOS TTL-compatible multiplexer/demultiplexer bus switch. The low on resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. When OE is LOW, S0 and S1 connect the A Port to the selected B Port output. When OE is HIGH, the FST3253MTCX is OPEN and a high-impedance state exists between the two ports.

Parametrics

FST3253MTCX absolute maximum ratings: (1)Supply Voltage (VCC): -0.5V to +7.0V; (2)DC Switch Voltage (VS): -0.5V to +7.0V; (3)DC Input Voltage (VIN): -0.5V to +7.0V; (4)DC Input Diode Current (lIK) VIN<0V: -50mA; (5)DC Output (IOUT) Sink Current: 128mA; (6)DC VCC/GND Current (ICC/IGND): +/- 100mA; (7)Storage Temperature Range (TSTG): -65℃ to +150℃.

Features

FST3253MTCX features: (1)4Ω switch connection between two ports; (2)Minimal propagation delay through the switch; (3)Low lCC; (4)Zero bounce in flow-through mode; (5)Control inputs compatible with TTL level.
