This device isfabricated using N-channel silicon-gate technology for highspeedand simple interface with MOS and bipolar circuits.All inputs (including program data inputs) can be driven bySeries 54/74 TTL circuits without the use of externalresistors. The data outputs are three-state for connectingmUltiple devices to a common bus.The TMS2564 is offered in a dual-in-line ceramic package(JL or JDL suffix) rated for operation from OOC to 70 0 C.The SMJ2564 is offered in a 28-pin dual-in-line ceramicpackage (J) and a leadless ceramic chip carrier (FE), ratedfor operation from - 55°C to 125°C. The J package isdesigned for insertion in mounting-hole rows on 600-mil(15,2 mm) centers, whereas the FE package is intended forsurface mounting on solder pads on 0.050-inch (1,27 mm)centers. The FE package offers a three-layer rectangularchip carrier with dimensions 0.450 x 0.550 x 0.1 00(11,43 x 13,97 x 2.54 mm).TMS2564 ... JL OR JDL PACKAGESMJ2564 ...
