Product Summary
The FST3126MTCX is a quad bus switch. It provides four high-speed CMOS TTL-compatible bus switches. The low on resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. The FST3126MTCX is organized as four 1-bit switches with separate OE inputs. When OE is HIGH, the switch is ON and Port A is connected to Port B. When OE is LOW, the switch is OPEN and a high-impedance state exists between the two ports.
Parametrics
FST3126MTCX 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)(Note 2): -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°C to +150 °C.
Features
FST3126MTCX 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.
