Overview
The 74HC221DB,112 is a dual non-retriggerable monostable multivibrator manufactured by Nexperia. It operates within a supply voltage range of 2 V to 6 V and features an operating temperature range from -40 °C to +125 °C. The device utilizes a 16-pin SSOP package and provides standard output capability. Key electrical characteristics include a propagation delay of 10 ns and output currents of 5.2 mA for both high and low states.
Feature Summary
- Dual non-retriggerable monostable multivibrator configuration
- Active LOW-going edge input (nA) and active HIGH-going edge input (nB)
- Overriding reset function terminates output pulse
- Pin-out identical to the 74HC123 series
Applications
- Pulse generation circuits
- Timing delays
- Debouncing switches
- Frequency division
Procurement Notes
Verify component authenticity through official Nexperia channels or authorized distributors. Confirm RoHS compliance status as specified in the datasheet. Ensure the SSOP-16 package matches your PCB footprint requirements. Check for end-of-life notices regarding this specific part number before finalizing procurement plans.
Selection Notes
Select this component when a dual monostable multivibrator with overriding reset is required. It serves as a direct pin-compatible replacement for the 74HC123. Consider the 2 V to 6 V supply voltage range and -40 °C to +125 °C operating temperature for industrial applications. Verify compatibility with LSTTL logic levels if interfacing with legacy systems.
Part Context
This device belongs to the 74HC/HCT/HCU/HCMOS logic family, designed for high-speed silicon-gate CMOS technology. It is compliant with JEDEC standard no. 7A and offers pin compatibility with low-power Schottky TTL (LSTTL) series components. The family is known for low power consumption and high noise immunity.
Replacement Considerations
The 74HC221DB,112 is pin-compatible with the 74HC123. Other valid substitutes include the 74HCT221D and 74LV423. Verify logic family voltage compatibility when selecting alternatives.
