Part Details:

SN54/74LS122SN54/74LS123 RETRIGGERABLE MONOSTABLEMULTIVIBRATORS These dc triggered multivibrators feature pulse width control by three meth- RETRIGGERABLE MONOSTABLE ods. The basic pulse width is programmed by selection of external resistance MULTIVIBRATORS and capacitance values. The LS122 has an internal timing resistor that allowsthe circuits to be used with only an external capacitor. Once triggered, the ba- LOW POWER SCHOTTKY sic 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 J SUFFIX · CERAMIC Internal Timing Resistors on LS122 CASE 620-09 16 1 SN54 / 74LS123 (TOP VIEW) (SEE NOTES 1 THRU 4) N SUFFIX 1 Rext/ 1 2 PLASTIC V C C CC ext ext 1Q 2Q CLR 2B 2A CASE 648-08 16 16 15 14 13 12 11 10 9 1 Q CLR Q D SUFFIX SOIC Q CLR
