ข้อมูลจําเพาะ
- 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 ata high logic level. To ensure the high-impedance state during power up or power down, (G\) should be tied to VCC through a pullup resistor; The minimum value of the resistor is determined by the current-sinking capability of the driver. Wide Operating Voltage Range of 2 V to 6 VHigh-Current Inverting Outputs Drive up to 15 LSTTL LoadsLow Power Consumption, 80-μA Max ICC'HC257 ...Typical tpd = 9 ns'HC258 ...Typical tpd = 12 ns±6-mA Output Drive at 5 VLow Input Current of 1 μA MaxProvides Bus Interface from Multiple Sources in High-Performance Systems
