Product Description

The SN74CB3Q3257PWR is a high-bandwidth FET Bus Switch utilizes a charge pump to elevate the gate voltage of the pass transistor, providing a low and flat ON-state resistance (ron). The low and flat ON-state resistance allows 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 SN74CB3Q3257 device provides an optimized interface solution ideally suited for broadband communications, networking and data-intensive computing systems. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry prevents damaging current backflow through the device when it is powered down. The device has isolation during power off.
Low and flat ON-state resistance (ron) characteristics over operating range (ron= 4R typical)
Rail-to-rail switching on data I/O ports
Bidirectional data flow with near-zero propagation delay
Low input and output capacitance minimizes loading and signal distortion
Fast switching frequency (f OE = 20MHz maximum)
Data and control inputs provide undershoot clamp diodes
low power consumption
Control inputs can be driven by TTL or 5/3.3V CMOS outputs
Ioff Supports partial-power-down mode operation
5V Tolerant I/Os with device powered up or powered down
Green product and no Sb/Br
