74F189 64-Bit Random Access Memory with 3-STATE Outputs April 1988 Revised July 1999 74F189 64-Bit Random Access Memory with 3-STATE Outputs General Description The F189 is a high-speed 64-bit RAM organized as a 16word by 4-bit array. Address inputs are buffered to minimize loading and are fully decoded on-chip. The outputs are 3-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 and the output data is the complement of the stored data. Features s 3-STATE outputs for data bus applications s Buffered inputs minimize loading s Address decoding on-chip s Diode clamped inputs minimize ringing Ordering Code: Order Number 74F189SC 74F189SJ 74F189PC Package Number M16B M16D N16E Package Description 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300” Wide 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300” Wide Devices also available in Tape and Reel.
