Description:	The 1702 is the static version of the 1701 (and 1601) The 1602A and 1702A are 256 word by 8-bit electrically programmable ROMs ideally suited for uses where fast turn-around and pattern experimentation are important. The 1602A and 1702A undergo complete programming and function testing on each bit position prior to shipment, thus insuring 100% programmability. The 1602A and 1702A use identical chips. The 1702A is packaged in a 24-pin dual in-line package with a transparent lid. The transparent lid allows the user to expose the chip to ultraviolet light to erase the bit pattern. A new pattern can then be written into the device. The 1602A is packaged in a 24-pin dual in-line package with a metal lid and is not erasable.
