CD74HC257

具有同向三态输出的高速 CMOS 逻辑四路 2 输入多路复用器

The ’HC257 and ’HCT257 are quad 2-input multiplexers which select four bits of data from two sources under the control of a common Select Input (S). The Output Enable input (OE\\) is active LOW. When OE\\ is HIGH, all of the outputs (1Y-4Y) are in the high impedance state regardless of all other inp • Buffered Inputs• Typical Propagation Delay (In to Output) = 12ns at VCC = 5V, CL = 15pF, TA = 25°C\n• Bus Driver Outputs...15 LSTTL Loads\n• Balanced Propagation Delay and Transition Times\n• HC Types \n• High Noise Immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V\n• Direct LSTTL Input Lo;
