Technical Specifications

The KM68V1002AJ-12 operates on a single 5V power supply and has a typical operating current of around 90mA. The standby current is significantly lower, typically around 10mA, further reducing power consumption when the device is not actively being accessed. It uses standard TTL logic levels for its inputs and outputs. The device is available in both DIP (Dual In-line Package) and SOJ (Small Outline J-lead) packages for flexible mounting options.

The address inputs, data inputs/outputs, and control signals are all designed to be fully TTL compatible, ensuring easy integration with other digital logic devices. The chip's high speed and low power consumption make it suitable for a wide range of applications where performance and energy efficiency are critical.
