10139
DESCRIPTION
The 10139 is an ECl 256-Bit Read Only Memory organized as 32 words with 8 bits per word. The words are selected by five binary address lines; full word decoding is incorporated on the chip. A chip enable input is provided for additional decoding flexibility, which causes all eight outputs to go to low state when the chip enable input is high. This device is fully patible with all of Signetics series 10,000 products. Address to output access time is 15 ns typical. Power dissipation is 580 milliwatts typical with separate internal bond wires and metal systems for VCC1 and VCC2. The 10139 may be programmed to any desired pattern by the user. The 10139 is suitable for use in high performance ECl systems. A Truth Table/Order Blank is attached.
