74HCT123PW,118

Multivibrators Overview

The Nexperia 74HCT123PW,118 is a dual retriggerable monostable multivibrator with reset housed in a 16-TSSOP package. 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 two independent circuits with propagation delays up to 77 ns at 4.5 V. Output currents are rated at 4 mA for both high and low states.

Multivibrators Feature Summary

• Dual retriggerable monostable multivibrator architecture with direct reset functionality
• TTL-compatible input levels ensuring compatibility with standard logic families
• Schmitt-trigger action on trigger inputs for tolerance to slow rise and fall times
• Integrated clamp diodes on inputs allowing interface to voltages exceeding VCC

Multivibrators Applications

• Timing pulse generation and shaping
• Debouncing of mechanical switches
• Frequency division and pulse width modulation

Multivibrators Procurement Notes

Verify the specific ordering suffix ',118' corresponds to the TSSOP16 (SOT403-1) package variant. Confirm that the TTL input level requirements align with the system's logic voltage standards. Ensure the design accounts for the specified operating temperature range and power dissipation derating characteristics for the selected package.

Multivibrators Selection Notes

Select this component when TTL-level triggering is required for monostable applications. The HCT series provides CMOS low power dissipation while maintaining TTL input thresholds. Consider the 16-TSSOP package dimensions if space constraints require a thin shrink small outline form factor compared to standard SOIC packages.

Multivibrators Part Context

This part belongs to the Nexperia 74HCT123 family, which includes variants such as the 74HC123 and 74AHCT123. These devices share the same functional description but differ in electrical specifications and input/output drive capabilities. The PW suffix specifically denotes the plastic thin shrink small outline package configuration.

Multivibrators Replacement Considerations

The 74HCT123DB,112 is listed as a similar replacement option, though it utilizes a different SSOP package format.
