to 2.5-V, 1.8-V to 3.3-V or 2.5 V to 3.3-V system.
High-speed operation : t
Output current : I
Latch-up performance: -300 mA
ESD performance: Machine model ≥ ±200 V
Ultra-small package: CSON8(CST8), SSOP8(US8)
Low current consumption : Using the new circuit significantly reduces current consumption when OE = “H”.
3.6-V tolerant function and power-down protection provided on all inputs and outputs.
Note: Do not apply a signal to any bus pins when it is in the output mode. Damage may result.
