20-Bit Bus Switch with −2V Undershoot Protection

General Description

Features

The Fairchild Switch FSTU16861 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.

■ Undershoot hardened to −2V (A and B Ports)

■ 4Ω switch connection between two ports

■ Minimal propagation delay through the switch

■ Low l_CC

■ Zero bounce in flow-through mode

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-

■ Control inputs compatible with TTL level

■ See Application Note AN-5008 for details

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. The A and B Ports are

protected against undershoot to support an extended

range to 2.0V below ground. Fairchild’s integrated Under-

shoot Hardened Circuit (UHC ) senses undershoot at the

I/O and responds by preventing voltage differentials from

developing and turning the switch on. When OE is HIGH,

the switch is OPEN and a high-impedance state exists

between the two ports.
