FST3125 - Quad Bus Switch

Description

The Fairchild Switch FST3125 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.

Features

  • s 4Ω switch connection between two ports. s Minimal propagation delay through the switch. s Low lCC. s Zero bounce in flow-through mode. s Control inputs compatible with TTL level. Ordering Code: Order Number FST3125M FST3125QSC FST3125MTC Package Number M14A MQA16 MTC14 Package.

FST3125 Quad Bus Switch August 1997 Revised December 1999 FST3125 Quad Bus Switch General Description The Fairchild Switch FST3125 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 LOW, the switch is ON and Port A is connected to Port B. When OE is HIGH, the switch is OPEN and a high-impedance state exists between the two ports. Features s 4Ω switch connection between two ports. s Minimal propagation delay through the switch. s Low lCC. s Zero bounce in flow-through mode. s Control inputs compatible with TTL level.
