General Description

The HT6116-70 is a 16384-bit static random access memory. It is organized with 2048 words of 8 bits in length, and operates with a single 5V power supply. The IC is built with a high performance CMOS 0.8µm process in order to obtain a low standby current and high reliability.

The IC contains six-transistor full CMOS memory cells and TTL compatible inputs and outputs, which are easily interface with common system bus structures. The Data bus of the HT6116-70 is designed as a tri-state type. The IC is in the standby mode if the CS pin is set to “high”.
