8.3 Feature Description

The SN74CB3Q3257 device has a high-bandwidth data path (up to 500 MHz) and has 5-V tolerant I/Os with the device powered up or powered down. It also has low and flat ON-state resistance (ron) characteristics over operating range (ron = 4 Ω Typical).

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

The SN74CB3Q3257 also provides a fast switching frequency (fOE = 20 MHz Max) with data and control inputs that provide undershoot clamp diodes as well as low power consumption (ICC = 0.6 mA Typical).

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

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