FST16213

24-Bit Bus Exchange Switch

General Description

The Fairchild Switch FST16213 provides 24-bits of high-

speed CMOS TTL-compatible bus switching or exchang-

ing. 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 operates as a 24-bit bus switch or a 12-bit bus

exchanger, which allows data exchange between the four

signal ports via the data-select terminals.

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.
