• Latch-up performance: ±300 mA

• ESD performance: Machine model ≥ ±200 V

Human body model ≥ ±2000 V

• Ultra-small package: VQON16

• Low current consumption: Using the new circuit significantly reduces current consumption when OE = “H”.

Suitable for battery-driven applications such as PDAs and cellular phones.

• Floating A-bus and B-bus are permitted. (when OE = “H”)

3.6-V tolerant function and power-down protection provided on all inputs and outputs.
