20-BIT FET BUS SWITCH

2.5-V/3.3-V LOW-VOLTAGE BUS SWITCH WITH 5-V-TOLERANT LEVEL SHIFTER

SCDS156A – OCTOBER 2003 – REVISED MARCH 2005

The SN74CB3T16210 is organized as two 10-bit bus switches with separate ouput-enable (1OE, 2OE) inputs. It

can be used as two 10-bit bus switches or as one 20-bit bus switch. When OE is low, the associated 10-bit bus

switch is ON, and the A port is connected to the B port, allowing bidirectional data flow between ports. When OE

is high, the associated 10-bit bus switch is OFF, and a high-impedance state exists between the A and B ports.

current will not backflow through the device when it is powered down. The device has isolation during power off.

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
