54F/74F219 64-Bit Random Access Memory with TRI-STATEÉ Outputs General Description Features The ’F219 is a high-speed 64-bit RAM organized as a 16-word by 4-bit array. Address inputs are buffered to minimize loading and are fully decoded on-chip. The outputs are TRI-STATE and are in the high-impedance state whenever the Chip Select (CS) input is HIGH. The outputs are active only in the Read mode. This device is similar to the ’F189 but features non-inverting, rather than inverting, data outputs. Y Commercial Y Y Y Y TRI-STATE outputs for data bus applications Buffered inputs minimize loading Address decoding on-chip Diode clamped inputs minimize ringing Available in SOIC (300 mil only) Package Number Military Package Description N16E 16-Lead (0.300× Wide) Molded Dual-In-Line J16A 16-Lead Ceramic Dual-In-Line 74F219SC (Note 1) M16B 16-Lead (0.300× Wide) Molded Small Outline, JEDEC 74F219SJ (Note 1) M16D 16-Lead (0.300× Wide) Molded Small Outline, EIAJ 54F219FL (Note 2) W16A 16-Lead Cerpack 54F219LL (Note 2) E20A 20-Lead Ceramic Leadless Chip Carrier, Type C 74F219PC 54F219DL (Note 2) Note 1: Devices also available in 13× reel.
