DESCRIPTION
The LVQ240 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. It has better speed performance at 3.3V than 5V LSTTL family combined with the true CMOS low power consumption. 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.
