Overview
The Nexperia 74HC123PW,118 is a dual retriggerable monostable multivibrator with reset housed in a 16-lead TSSOP package. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features Schmitt-trigger inputs for noise immunity and includes clamp diodes for high-voltage interfacing. Propagation delay typically reaches 65 ns at 6.0 V, with output currents up to 5.2 mA.
Feature Summary
- Dual independent monostable circuits with direct reset functionality
- Schmitt-trigger action on trigger inputs for slow signal tolerance
- Wide operating voltage range supporting CMOS and TTL logic levels
- High ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)
Applications
- Pulse width generation and timing control
- Frequency division and pulse stretching
- Debouncing switches or mechanical contacts
Procurement Notes
Verify the specific ordering suffix matches the required package variant. Confirm RoHS compliance status against current manufacturing data sheets. Ensure the temperature grade aligns with system requirements. Validate pinout compatibility during PCB layout finalization. Cross-reference datasheet revision history for any recent specification updates.
Selection Notes
Select this component when dual independent timing channels are required in a compact surface-mount footprint. The TSSOP16 package offers thermal performance suitable for dense layouts. Verify that external timing components meet the specified resistance and capacitance ranges for accurate pulse width calculation.
Part Context
This part belongs to the 74HC/HCT logic family, providing standard digital interface compatibility. It serves as a replacement for legacy SSOP variants like the 74HCT123DB. The PW suffix specifically denotes the thin shrink small outline plastic package configuration used in modern electronics assembly.
Replacement Considerations
The discontinued 74HCT123DB is a confirmed substitute offering identical logical functionality in an SSOP16 package.
