CXK3864 SONY 8K-Word X 8 bit Mask Programmable ROM Description Package Outline The CXK3864 is a CMOS mask-programmable ROM organized as 8.192 words by 8 bits. The Chip Enable input deselects the outputs and puts the chip in a power down mode. The active level of the Output Enable is defined by the customer. Unit: mm 28 pin DIP (P typel Features • Fast access time: 200 ns Max • Automatic power down • Fully static operation. .. No clock or timing strobe required • Pin compatible with EPROM i2764 • Directly TTL compatible: All inputs and outputs • Three state output • Single +5V supply • Low power dissipation 165 mW maximum (active. unloaded. 200 ns cycle rate) 16.5 mW maximum (standby. TTL inputs) 165 p.W maximum (standby. full rail inputs) Structure Silicon gate CMOS IC Function 8.192-word X 8 bit mask-programmable ROM - 91 - 28 pin MFP (M type' 18.4 MAX 2.7 MAX I SONY.
