74LVC1G123GF,115

Overview

The Nexperia 74LVC1G123GF,115 is a single retriggerable monostable multivibrator featuring Schmitt trigger inputs. It operates within a supply voltage range of 1.65 V to 5.5 V and supports an output drive of ±24 mA at 3.0 V. The device provides high noise immunity and low power consumption. It includes IOFF circuitry for partial power-down applications to prevent backflow current. The component is specified for ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Retriggerable operation allows extension of the output pulse width up to a 100% duty factor via active HIGH or LOW edge inputs.
• Schmitt trigger action on all inputs ensures tolerance to slower input rise and fall times.
• IOFF circuitry disables outputs during power-down to prevent damaging backflow currents.
• Direct reset input terminates the output pulse immediately.

Applications

• Pulse generation and timing circuits
• Debouncing switches and contacts
• Frequency division
• Timing delays

Procurement Notes

Verify the specific package designation GF corresponds to the required footprint and thermal characteristics. Confirm that the ordering suffix matches the intended tape and reel configuration. Ensure the selected variant meets the required operating temperature range and electrical specifications for the target application environment.

Selection Notes

Select this component when a single-channel monostable multivibrator with Schmitt triggers is required. Consider the wide supply voltage compatibility for mixed 3.3 V and 5 V logic environments. Evaluate the external resistor and capacitor requirements for desired pulse widths. Verify package availability against board space constraints.

Part Context

This part belongs to the 74LVC1G123 family of single retriggerable monostable multivibrators. The family offers multiple package options including TSSOP, VSSOP, and XSON variants. All versions share identical functional characteristics and electrical parameters defined in the product data sheet.

Replacement Considerations

Cross-reference other 74LVC1G123 variants such as 74LVC1G123DP or 74LVC1G123GS if package differences are acceptable. Ensure pinout compatibility and verify that alternative packages meet the same thermal and mechanical requirements.
