64M-Bit (4Mx16) CMOS MASK ROM
FEATURES
CMOS MASK ROM
GENERAL DESCRIPTION
· 4,194,304 x 16 bit organization
· Fast access time : 120ns(Max.)
· Supply voltage : single +5V
· Current consumption
Operating : 70mA(Max.)
· Fully static operation
· All inputs and outputs TTL compatible
· Three state outputs
· Package
The K3N7C4000M-DC is a fully static mask programmable
ROM organized 4,194,304 x 16 bit. It is fabricated using sili-
con-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.
-. K3N7C4000M-DC : 42-DIP-600
The K3N7C4000M-DC 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.
