CD74HCT221

具有复位功能的高速 CMOS 逻辑双路单稳态多谐振荡器

The ’HC221 and CD74HCT221 are dual monostable multivibrators with reset. An external resistor (RX) and an external capacitor (CX) control the timing and the accuracy for the circuit. Adjustment of RX and CX provides a wide range of output pulse widths from the Q and Q\\ terminals. Pulse triggering o; • Overriding RESET Terminates Output Pulse\n• Triggering from the Leading or Trailing Edge\n• Q and Q\\ Buffered Outputs\n• Separate Resets\n• Wide Range of Output-Pulse Widths\n• Schmitt Trigger on B Inputs\n• Fanout (Over Temperature Range) \n• Standard Outputs . . . . 10 LSTTL Loads\n• Bus Driver;
