SN74HC257

具有三态输出的四路 2 线路到 1 线路数据选择器/多路复用器

These devices are designed to multiplex signals from 4-bit data sources to 4-output data lines in bus-organized systems. The 3-state outputs do not load the data lines when the output-enable (G\\) input is at a high logic level.\n\n To ensure the high-impedance state during power up or power down, ( • Wide Operating Voltage Range of 2 V to 6 V\n• High-Current Inverting Outputs Drive up to 15 LSTTL Loads\n• Low Power Consumption, 80-µA Max ICC\n• ’HC257 ...Typical tpd = 9 ns\n• ’HC258 ...Typical tpd = 12 ns\n• ±6-mA Output Drive at 5 V\n• Low Input Current of 1 µA Max\n• Provides Bus Interface f;
