Product Summary
The FSTU3257QSCX is a quad 2:1 high-speed CMOS TTL-compatible multiplexer/demultiplexer bus switch. The low on resistance of the FSTU3257QSCX allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. When OE is LOW, the select pin connects the A Port to the selected B Port output. The A and B Ports are “undershoot hardened” with UHC protection to support an extended range of 2.0V below ground.
Parametrics
FSTU3257QSCX absolute maximum ratings: (1)Supply Voltage (VCC): -0.5V to +7.0V; (2)DC, Switch Voltage (VS): -2.0V to +7.0V; (3)DC, Input Control Pin Voltage (VIN): -0.5V to +7.0V; (4)DC, Input Diode Current (lIK) VIN<0V: -50mA; (5)DC, Output (IOUT): 128mA; (6)DC, VCC/GND Current (ICC/IGND): +/-100mA; (7)Storage Temperature Range (TSTG): -65℃ to +150℃.
Features
FSTU3257QSCX features: (1)Undershoot hardened to .2V (A and B Ports); (2)Soft enable turn-on to minimize bus to bus charge sharing during enable; (3)4Ω switch connection between two ports; (4)Minimal propagation delay through the switch; (5)Low lCC; (6)Zero bounce in flow-through mode; (7)Control inputs compatible with TTL level; (8)See Applications Note AN-5008 for details.
