74LS12規(guī)格書詳情
These dc triggered multivibrators feature pulse width control by three methods. The basic pulse width is programmed by selection of external resistance and capacitance values. The LS122 has an internal timing resistor that allows the circuits to be used with only an external capacitor. Once triggered, the basic pulse width may be extended by retriggering the gated low-level-active (A) or high-level-active (B) inputs, or be reduced by use of the overriding clear.
? Overriding Clear Terminates Output Pulse
? Compensated for VCC and Temperature Variations
? DC Triggered from Active-High or Active-Low Gated Logic Inputs
? Retriggerable for Very Long Output Pulses, up to 100 Duty Cycle
? Internal Timing Resistors on LS122
