64-Bit Random Access Memory with 3-STATE Outputs General Description The 74F219 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 3-STATE and are in the high-impedance state whenever the Chip Select (CS) input is HIGH. The outputs are | Fairchild 仙童半导体 | |||
64-bit TTL bipolar RAM, non-inverting 3-State DESCRIPTION The 74F219A 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 in high impedance state whenever the chip enable (CE) is high. The outputs are active only in the READ mode (WE | Philips 飞利浦 | |||
