LOW POWER SCHOTTKY Quad 2-Input Multiplexer with 3-State Outputs The LSTTL/MSI SN74LS257B and the SN74LS258B are Quad 2-Input Multiplexers with 3-state outputs. Four bits of data from two sources can be selected using a Common Data Select input. The four outputs present the selected data in true (non-inverted) | ONSEMI 安森美半导体 |   | ||
3-STATE Quad 2-Data Selectors/Multiplexers General Description These Schottky-clamped high-performance multiplexers feature 3-STATE outputs that can interface directly with data lines of bus-organized systems. With all but one of the common outputs disabled (at a high impedance state), the low impedance of the single enabled output will d | FairchildFairchild Semiconductor 仙童半导体飞兆/仙童半导体公司 | | ||
