74V2T07
TRIPLE BUFFER (OPEN DRAIN)
s HIGH SPEED: tPD = 4.3ns (TYP.) at VCC = 5V
s LOW POWER DISSIPATION:
ICC = 1µA(MAX.) at TA = 25°C
s COMPATIBLE WITH TTL OUTPUTS:
VIH = 2V (MIN), VIL = 0.8V (MAX)
s POWER DOWN PROTECTION ON INPUT
s OPERATING VOLTAGE RANGE:
VCC(OPR) = 4.5V to 5.5V
s IMPROVED LATCH-UP IMMUNITY
DESCRIPTION
The 74V2T07 is an advanced high-speed CMOS
TRIPLE BUFFER (OPEN DRAIN) fabricated with
sub-micron silicon gate and double-layer metal
wiring C2MOS 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 input and 0
to 7V can be accepted on input 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 operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/3
