NLV14538BDWG

The operating temperature range for the MC14538B is -55 to +125 °C .

The duration and accuracy of the output pulse are determined by the external timing components, specifically the capacitor (CX) and resistor (RX) values used in the circuit. The output pulse width (T) is calculated using the formula T = RX * CX, where RX is the resistor value in ohms and CX is the capacitor value in farads .

The purpose of the MC14538B is to function as a dual, retriggerable, resettable monostable multivibrator. It can be triggered from either edge of an input pulse and produces an accurate output pulse over a wide range of widths, with the duration and accuracy determined by external timing components, C X and R X. The output pulse width is calculated using the formula T = R X / C X . The operation of the MC14538B involves trigger operation where the monostable is in a quiescent state before an input trigger occurs. When a valid trigger is recognized, the capacitor C X rapidly discharges and then charges through the timing resistor R X, resulting in the generation of an output pulse. The output latch is set via the input trigger, independent of the capacitor voltage, ensuring a consistent propagation delay from trigger to Q . In summary, the MC14538B serves as a versatile dual monostable multivibrator with retriggerable and resettable capabilities, providing accurate output pulses based on external timing components and offering various features for flexible operation .
