Configurable 4-Bit to 20-Bit Bus Switch with

-2V Undershoot Protection and Selectable Level Shifting

General Description

Features

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

The Fairchild Universal Bus Switch FSTUD16450 provides

4-bit, 5-bit, 8-bit, 10-bit, 16-bit, 20-bit 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.

■ Voltage level shifting

■ 4Ω switch connection between two ports

■ Minimal propagation delay through the switch

■ Low l_CC

The FSTUD16450 is designed to allow “customer” configu-

ration control of the enable connections. The device is

organized as either a 4-bit, 5-bit, 10-bit or 20-bit bus switch.

8-bit and 16-bit configurations are also achievable (see

Functional Description). The device's bit configuration is

chosen through select pin logic. (see Truth Table). When

OE_xis LOW, Port A_xis connected to Port B_x. When OE_xis

■ Zero bounce in flow-through mode

■ Control inputs compatible with TTL level

■ See Applications Note AN-5008 for details

■ Also packaged in plastic Fine-Pitch Ball Grid Array

(FBGA) (Preliminary)

Applications Note

Select pins S₀, S₁, S₂are intended to be used as static

user configurable control pins. The AC performance of

these pins has not been characterized or tested. Switching

of these select pins during system operation may tempo-

rarily disrupt output logic states and/or enable pin controls.

HIGH, the switch is OPEN.

The A and B Ports are “undershoot hardened” with UHC

protection to support an extended range to 2.0V below

ground. Fairchild's integrated “Undershoot Hardened

Circuit” (UHC) senses undershoot at the I/O's, and

responds by preventing voltage differentials from develop-

ing and turning on the switch.

Another key device feature is the addition of a level shifting

select pin, “S₂”. When S₂is LOW, the device behaves as a

standard N-MOS switch. When S₂is HIGH, a diode to V_CC

is integrated into the circuit allowing for level shifting

between 5V inputs and 3.3V outputs.
