74HC123PW,112

Overview

The Nexperia 74HC123PW,112 is a dual retriggerable monostable multivibrator housed in a 16-lead TSSOP package. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device features Schmitt-trigger inputs for noise immunity and includes direct reset functionality. Propagation delay typically reaches 65 ns at 5 V, with static current consumption as low as 8 µA.

Feature Summary

• Dual retriggerable monostable multivibrator architecture
• Schmitt-trigger action on trigger inputs for slow signal tolerance
• Direct reset input capability to terminate output pulses
• CMOS low power dissipation with high noise immunity

Applications

• Timing pulse generation
• Frequency division
• Waveform shaping
• Delay line circuits

Procurement Notes

Verify the specific ordering suffix '112' against the manufacturer's latest documentation to confirm the exact tape-and-reel packaging configuration. Confirm RoHS compliance status and ensure the component meets the required JEDEC standards for your specific application environment before finalizing procurement.

Selection Notes

Select this component when a dual-channel monostable solution is required with Schmitt-trigger inputs. Ensure the external timing components (REXT and CEXT) are chosen to meet the desired pulse width specifications. Verify that the operating voltage falls within the 2.0 V to 6.0 V range and that the thermal requirements are met by the TSSOP16 package.

Part Context

This part belongs to the Nexperia 74HC/HCT123 family of dual retriggerable monostable multivibrators. The 'HC' designation indicates CMOS logic levels, while the 'PW' suffix specifies the TSSOP16 plastic thin shrink small outline package. It is designed for general-purpose timing applications requiring robust noise immunity and flexible triggering options.

Replacement Considerations

The 74HCT123PW,118 is a TTL-level compatible alternative within the same package. For HC-series replacements, verify pin compatibility and electrical characteristics. Note that the 74HC123D variant uses an SO16 package, which may require PCB layout adjustments.
