1MS2516, SMJ251616,384-B11 ERASABLE PROGRAMMABLE READ-ONLY. MEMORIESThe TMS2516s are offered in a dual-in-line cerpak package (JL suffix), rated for operation form ooe to 70oe. TheSMJ' devices are offered in a 24-pin dual-in-line ceramic package (J) and in a 32-pad lead less ceramic chip carrier(FG). The J package is designed for insertion in mounting-hole rows on 600-mil (15,2 mm) centers, whereas the FGpackage is intended for surface mounting on solder pads on 0.050-inch (1,27 mm) centers. The FG package offersa three layer rectangular chip carrier with dimensions 0.450 x 0.550 x 0.1 00 (11,42 x 13,97 x 2,54).Since these EPROMs operate from a single + 5 V supply (in the read mode), they are ideal for use in microprocessorsystems. One other ( + 25 V) supply is needed for programming but all programming signals are TTL level, requiringa single 10-ms pulse. For programming outside of the system, existing EPROM programmers can be used. Locationsmay be programmed singly, in blocks, or at random. Total programming time for all bits is 20 seconds.operationMODEFUNCTIONOutput Start Inhibit Program(PINS) Read Power DownDisable Programming Programming VerificationPD/PGM Don't Pulsed VIL(18)VILCareVIHto VIHVILVILSDon't(20)VIL VIHCareVIH VIH VILVpp+25 V+5 V +5 V +5V +25 V +25 V(21) (or +5 VIVCC(24)Q+5 V +5 V+5 V +5 V +5 V +5 V(9 to 11, Q HI-Z HI-Z D HI-Z Q13 to 17)m"'0::Dos:cCD
