FST3126 General Description

The Fairchild Switch FST3126 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 device 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.

FST3126 Maximum Ratings

Supply Voltage (VCC)................................................ −0.5V to +7.0V
DC Switch Voltage (VS)............................................. −0.5V to +7.0V
DC Input Voltage (VIN) (Note 2)............................... −0.5V to +7.0V
DC Input Diode Current (lIK) VIN<0V .....................................−50mA
DC Output (IOUT) Sink Current ..............................................128mA
DC VCC/GND Current (ICC/IGND) ......................................+/− 100mA
Storage Temperature Range (TSTG) ..................−65°C to +150 °C

FST3126 Features

•4Ω switch connection between two ports.
•Minimal propagation delay through the switch.
•Low lCC.
•Zero bounce in flow-through mode.
•Control inputs compatible with TTL level.
