DESCRIPTION

The 74V1G126 is an advanced high-speed CMOS SINGLE BUS BUFFER fabricated with sub-micron silicon gate and double-layer metal wiring C 2MOS technology. 3-STATE control input 1G has to be set LOW to place the output into the high impedance state. 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. 74V1G126 SINGLE BUS BUFFER (3-STATE) PIN CONNECTION AND IEC LOGIC SYMBOLS ORDER CODES PACKAGE T & R SOT23-5L 74V1G126STR SOT323-5L 74V1G126CTR SOT323-5LSOT23-5L

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.
