DESCRIPTION
The 74V1T70 is an advanced high-speed CMOS
SINGLE BUFFER 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.

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
