DESCRIPTION
The 74V1G70 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 no ise
immunity and stable output.
Power down protection is provided on inpu t an d 0
to 7V can be acce pted on inp ut with no rega rd to
the supply voltage. This device can be used to
interface 5V to 3V.

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. (R ef er to Test Circui t ). Average ope rating curre nt can be obtained by the follow i ng equation. I
