74HCT123D-Q100,115

Overview

The Nexperia 74HCT123D-Q100,115 is a dual retriggerable monostable multivibrator with reset, manufactured by Nexperia USA Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features Schmitt-trigger inputs for noise immunity and includes clamp diodes for overvoltage tolerance. It is qualified to AEC-Q100 Grade 1 standards for automotive applications.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 (Grade 1)
• Dual retriggerable monostable multivibrator with direct reset functionality
• Schmitt-trigger action on nA and nB inputs for slow signal tolerance
• Inputs include clamp diodes for interfacing with voltages exceeding VCC

Applications

• Automotive electronic systems requiring pulse generation or timing control
• Timing delay circuits utilizing external resistor and capacitor components
• Pulse width modulation and frequency division applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and availability. Confirm that the component meets the required AEC-Q100 Grade 1 qualification level for your specific application environment. Ensure compatibility with the intended operating temperature range and supply voltage specifications before finalizing procurement.

Selection Notes

Select this component when TTL-compatible logic levels are required for triggering inputs. Choose this part for designs needing dual independent monostable channels within a single package. Consider the SO16 plastic small outline package for standard surface-mount assembly processes. Verify that the external timing components can support the desired pulse width calculations based on the datasheet formulas.

Part Context

This device belongs to the Nexperia 74HCT123-Q100 series, which includes variants such as the 74HC123-Q100 and other package options like TSSOP16 and DHVQFN16. The HCT series specifically ensures compatibility with Low-power Schottky TTL (LSTTL) logic families while maintaining CMOS low power dissipation characteristics.

Replacement Considerations

The 74HCT123D-Q100 is functionally compatible with other 74HCT123 variants in the same family. Check the datasheet for alternative package versions such as the 74HCT123PW-Q100 if different footprint dimensions are required.
