FST34X2245

32-Bit Bus Switch with 25: Series Resistors in Outputs

General Description

The Fairchild Switch FST34X2245 provides 32-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.

The device is organized as a 32-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.

The FST34X2245 has equivalent 25

reduce signal-reflection noise, eliminating the need for

external terminating resistors.

Ordering Code:

Note 1: “_NL” indicates Pb-Free product (per JEDEC J-STD-020B). Device is available in Tape and Reel only.
