20-Bit Bus Switch

General Description

Features

The Fairchild Switch FST16861 provides 20-Bits of high-

speed 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.

■ 4Ω switch connection between two ports.

■ Minimal propagation delay through the switch.

■ Low l_CC

■ Zero bounce in flow-through mode.

■ Control inputs compatible with TTL level.

The device is organized as a 10-bit or 20-Bit bus switch.

When OE₁is LOW, the switch is ON and Port 1A is con-

nected to Port 1B. When OE₂is LOW, Port 2A is connected

to Port 2B. When OE_Xis HIGH, a high impedance state

exists between the A and B Ports.
