CMOS MASK ROM  
64M-Bit (4Mx16) CMOS MASK ROM  
FEATURES  
GENERAL DESCRIPTION  
· 4,194,304 x 16 bit organization  
· Fast access time : 100ns(Max.)  
· Supply voltage : single +5V  
· Current consumption  
Operating : 70mA(Max.)  
· Fully static operation  
· All inputs and outputs TTL compatible  
· Three state outputs  
· Package  
The KM23C64000B is a fully static mask programmable ROM  
organized 4,194,304 x 16 bit. It is fabricated using silicon-gate  
CMOS process technology.  
This device operates with a 5V single power supply, and all  
inputs and outputs are TTL compatible.  
Because of its asynchronous operation, it requires no external  
clock assuring extremely easy operation.  
It is suitable for use in program memory of microprocessor and  
data memory, character generator.  
-. KM23C64000B : 42-DIP-600  
The KM23C64000B is packaged in a 42-DIP.

NOTE : Minimum DC Voltage(VIL) is -0.3V an input pins. During transitions, this level may undershoot to -2.0V for periods <20ns.  
Maximum DC voltage on input pins(VIH) is VCC+0.3V which, during transitions, may overshoot to VCC+2.0V for periods <20ns.
