74V2T08STR
The internal circuit is composed of 2 stages
including buffer output, which provide high noise
immunity and stable output.
Power down protection is provided on all inputs
and outputs and 0 to 7V can be accepted on
inputs with no regard to the supply voltage.
This device can be used to interface 5V to 3V.

1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
load. (Refer to Test Circuit). Average current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/2
