DESCRIPTIONThe 74V1T32 is an advanced high-speed CMOS
SINGLE 2-INPUT OR GATE fabricated with
sub-micron silicon gate and double-layer metal
wiring C2 MOS technology.
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 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.

ABSOLUTE MAXIMUM RATINGS Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these conditions is
not implied
RECOMMENDED OPERATING CONDITIONS 1) VIN from 0.8V to 2V

DC SPECIFICATIONS
AC ELECTRICAL CHARACTERISTICS (Input tr = tf = 3ns) (*) Voltage range is 5.0V ± 0.5V
CAPACITIVE CHARACTERISTICS 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 operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC
