FST3244WM - Octal Bus Switch

Download the FST3244WM datasheet PDF. This datasheet also covers the FST variant, as both devices belong to the same octal bus switch family and are provided as variant models within a single manufacturer datasheet.

General Description

The Fairchild Switch FST3244 provides 8-bits of highspeed CMOS TTL-compatible bus switching in a standard ’244 pin-out.

The low on resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise.

Key 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 FST3244WM FST3244QSC FST3244MTC Package Number M20B MQA20 MTC20 Package.

FST3244 Octal Bus Switch June 1997 Revised December 1999 FST3244 Octal Bus Switch General Description The Fairchild Switch FST3244 provides 8-bits of highspeed CMOS TTL-compatible bus switching in a standard ’244 pin-out. 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 two 4-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.
