FST3345QSC - 8-Bit Bus Switch

Download the FST3345QSC datasheet PDF. This datasheet also covers the FST variant, as both devices belong to the same 8-bit bus switch family and are provided as variant models within a single manufacturer datasheet.

Description

The Fairchild Switch FST3345 provides 8-bits of highspeed CMOS TTL-compatible bus switching.

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 4: 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 FST3345WM FST3345QSC FST3345MTC FST3345MTCX_NL (Note 1) Package Number M20B MQA20 MTC20 MTC20 Package.

FST3345 8-Bit Bus Switch June 1997 Revised March 2005 FST3345 8-Bit Bus Switch General Description The Fairchild Switch FST3345 provides 8-bits of highspeed CMOS TTL-compatible bus switching. 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 an 8-bit switch bank with dual output enable inputs (OE and OE). When OE is LOW or OE is HIGH, the switch is ON and Port A is connected to Port B. When OE is HIGH and OE is LOW, the switch is OPEN and a high-impedance state exists between the two ports. Features s 4: switch connection between two ports. s Minimal propagation delay through the switch. s Low lCC. s Zero bounce in flow-through mode.
