DESCRIPTION

· The 74LV123 is a dual retriggerable monostable multivibrator with reset.

· The output pulse width is programmable via external components (R EXT and C EXT).

· The pulse width can be extended by retriggering edge-triggered inputs (nA or nB).

· Output delay can be terminated by a LOW-going edge on input nRD.

· Features Schmitt-trigger action on nA and nB inputs for tolerance to slower input rise and fall times.

FEATURES

· Wide supply voltage range: 1.0 V to 5.5 V.

· CMOS low power dissipation.

· Latch-up performance exceeds 100 mA per JESD 78 Class II Level B.

· Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V.

· Retriggerable for long pulses up to 100% duty factor.

· Direct reset terminates output pulses.

· Schmitt-trigger action on all inputs except reset.

· ESD protection: HBM exceeds 2000 V, CDM exceeds 1000 V.

· Specified from -40 °C to +125 °C.

APPLICATIONS

· Suitable for low-voltage applications: 1.0 V to 3.6 V.

· Ideal for systems requiring precise timing control.

· Used in environments requiring robust ESD protection.

· Applicable in circuits needing retriggerable monostable multivibrators.

· Suitable for use in industrial temperature ranges.
