7.3 Feature Description

The SN74CB3Q3253 device has a high-bandwidth data path (up to 500MHz) and has 5V tolerant I/Os with the device powered up or powered down. The device also has low and flat ON-state resistance (ron) characteristics over operating range (ron = 4Ω Typical)

This device also has rail-to-rail switching on data I/O ports for 0- to 5V switching with 3.3V VCCand 0- to 3.3V switching with 2.5V VCCas well as bidirectional data flow with near-zero propagation delay and low input and output capacitance that minimizes loading and signal distortion (Cio(OFF) = 3.5pF Typical)

The SN74CB3Q3253 also provides a fast switching frequency (fOE = 20MHz Maximum) with data and control inputs that provide undershoot clamp diodes as well as low power consumption (ICC = 0.6mA Typical)

The VCC operating range is from 2.3V to 3.6V and the data I/Os support 0V to 5V signal levels of (0.8V, 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5V)

The control inputs can be driven by TTL or 5V and 3.3V CMOS outputs as well as Ioff Supports Partial-Power-Down Mode Operation
