16-Bit Bus Switch

General Description

Features

■ 4Ω switch connection between two ports

■ Minimal propagation delay through the switch

■ Low l_CC

The Fairchild Switch FST32X245 provides 16-bits of high

speed CMOS TTL-compatible bus switching in a standard

flow-through mode. The low On Resistance of the switch

allows inputs to be connected to outputs without adding

propagation delay or generating additional ground bounce

noise.

■ Zero bounce in flow-through mode

■ Control inputs compatible with TTL level

■ 16-bit version of FST3245

The device is organized as a 16-bit switch. 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-imped-

ance state exists between the two ports.
