DESCRIPTION

The 74V2T07 is an advanced high-speed CMOS TRIPLE BUFFER (OPEN DRAIN) fabricated with sub-micron silicon gate and double-layer metal wiring C 2MOS 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 i n t e r f a c e5 Vt o3 V . 74V2T07 TRIPLE BUFFER (OPEN DRAIN) PIN CONNECTION AND IEC LOGIC SYMBOLS ORDER CODES PACKAGE T & R SOT23-8L 74V2T07STR SOT23-8L

AC ELECTRICAL CHARACTERISTICS (Input tr=tf=3 n s ) (*) 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.
