Overview
The 74LV74N,112 is a dual D-type flip-flop manufactured by NXP USA Inc. It operates within a supply voltage range of 1.0V to 5.5V and supports TTL input levels between VCC = 2.7V and VCC = 3.6V. The device features positive-edge triggering with set and reset inputs. It is housed in a 14-DIP package and functions as a low-voltage Si-gate CMOS device compatible with 74HC/HCT74 standards.
Feature Summary
- Dual D-type flip-flop architecture with positive-edge triggering
- Wide operating voltage range from 1.0V to 5.5V
- TTL input level acceptance at specific supply voltages
- Pin and function compatibility with 74HC/HCT74 series
Applications
- Low voltage digital logic applications
- Data storage and transfer registers
- Timing and control circuits
- General purpose sequential logic systems
Procurement Notes
Verify the exact suffix '112' against official Nexperia/NXP documentation to confirm package type and manufacturing origin. Confirm RoHS compliance status for the specific batch. Check for end-of-life notices or obsolescence warnings prior to procurement. Ensure the DIP-14 package matches the target PCB footprint requirements.
Selection Notes
Select this component when dual D-type flip-flops are required with wide voltage flexibility. It serves as a drop-in replacement for 74HC/HCT74 devices in designs needing 1.0V to 5.5V operation. Consider the DIP-14 package for through-hole mounting needs. Verify input threshold compatibility if interfacing with TTL logic sources.
Part Context
This part belongs to the 74LV (Low Voltage) logic family produced by NXP Semiconductors. It is designed for applications requiring operation across a broad voltage spectrum while maintaining compatibility with standard logic interfaces. The device is widely used in consumer electronics and industrial control systems where voltage translation and reliable data storage are necessary.
Replacement Considerations
Public confirmed substitutes include 74LV74D and 74LV74-Q100 from Nexperia. Texas Instruments offers the SN74LV74A as a functional equivalent. Verify pinout and electrical specifications before substitution.
