DESCRIPTION

The 74V2T08 is an advanced high-speed CMOS
DUAL 2-INPUT AND GATE fabricated with
sub-micron silicon gate and double-layer metal
wiring C2 MOS tecnology.
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.

AC ELECTRICAL CHARACTERISTICS (Input tr = tf = 3ns)

(*) Voltage range is 3.3V ± 0.3V
(**) Voltage range is 5.0V ± 0.5V
CAPACITANCE CHARACTERISTICS

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