    Products Detail

    Dual monostable multivibrators with reset. External resistor (RX) and capacitor (CX) control timing and accuracy. Adjustment of RX and CX provides a wide range of output pulse widths from the Q and Q terminals. Triggering on the B input occurs at a particular voltage level and is not related to the rise and fall time of the trigger pulse. Once triggered, the outputs are independent of further trigger inputs on A and B. The output pulse can be terminated by a LOW level on the Reset (R) pin. Trailing edge triggering (A) and leading-edge triggering (B) inputs are provided for triggering from either edge of the input pulse. On power up, the IC is reset.

    Key Features

    • Overriding RESET Terminates Output Pulse
    • Triggering from the Leading or Trailing Edge
    • Q and Q Buffered Outputs
    • Separate Resets
    • Wide Range of Output-Pulse Widths
    • Schmitt Trigger on B Inputs
    • Fanout (Over Temperature Range): Standard Outputs: 10 LSTTL Loads, Bus Driver Outputs: 15 LSTTL Loads
    • Wide Operating Temperature Range: -55°C to 125°C
    • Balanced Propagation Delay and Transition Times
    • Significant Power Reduction Compared to LSTTL
    • HC Types: 2V to 6V Operation, High Noise Immunity: NIL = 30%, NIH = 30% of VCC
    • HCT Types: 4.5V to 5.5V Operation, Direct LSTTL Input Logic Compatibility, CMOS Input Compatibility
