SN74CB3Q16244
16-BIT FET BUS SWITCH
2.5-V/3.3-V LOW-VOLTAGE HIGH-BANDWIDTH BUS SWITCH
SCDS168 – MAY 2004 – REVISED MARCH 2005
DESCRIPTION/ORDERING INFORMATION
The SN74CB3Q16244 is a high-bandwidth FET bus switch utilizing a charge pump to elevate the gate voltage of
the pass transistor, providing a low and flat ON-state resistance (r
for minimal propagation delay and supports rail-to-rail switching on the data input/output (I/O) ports. The device
also features low data I/O capacitance to minimize capacitive loading and signal distortion on the data bus.
Specifically designed to support high-bandwidth applications, the SN74CB3Q16244 provides an optimized
interface solution ideally suited for broadband communications, networking, and data-intensive computing
systems.
The SN74CB3Q16244 is organized as four 4-bit bus switches with separate output-enable (1OE, 2OE, 3OE,
4OE) inputs. It can be used as four 4-bit bus switches, two 8-bit bus switches, or one 16-bit bus switch. When
OE is low, the associated 4-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 4-bit bus switch is OFF, and a high-impedance state
exists between the A and B ports.
This device is fully specified for partial-power-down applications using I
current backflow through the device when it is powered down. The device has isolation during power off.
To ensure the high-impedance state during power up or power down, OE should be tied to V
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
