74V2G126CTR

双总线缓冲器（三态） DUAL BUS BUFFER 3-STATE

DESCRIPTION

The 74V2G126 is an advanced high-speed CMOS DUAL BUS BUFFER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.3-STATE control input nG has to be set LOW to place the output into the high impedance state. Power down protection is provided on all inputs and outputs and 0 to 7V can be accepted oninputs with no regard to the supply voltage. This device can be used to interface 5V to 3V systems and it is ideal for portable applications like

personal digital assistant, camcorder and all battery-powered equipment.
