74LVQ240集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF中文资料

DESCRIPTION

The 74LVQ240 is a low voltage CMOS OCTAL BUS BUFFER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power and low noise 3.3V applications. G output control governs four BUS BUFFERs. This device is designed to be used with 3 state memory address drivers, etc. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
