Overview
The 74LVC374AE4Q is an octal D-type flip-flop with 3-state outputs manufactured by IDT. It operates within a voltage range of 1.65V to 3.6V and features 5V tolerant inputs. The device utilizes advanced CMOS technology for high-speed performance, offering symmetrical output impedance and power-down protection on all inputs and outputs. It ensures balanced propagation delays and provides ESD immunity exceeding 2000V per MIL-STD-883. The component is designed for applications requiring reliable data storage and bus interfacing in low-voltage systems.
Feature Summary
- Octal D-type flip-flop architecture with 3-state outputs
- 5V tolerant inputs compatible with standard logic levels
- Power-down protection on all I/O pins
- High ESD immunity exceeding 2000V HBM
Applications
- Parallel data storage in digital systems
- Bus interface circuits for memory mapping
- Clocked data registration in communication modules
- Level shifting between 3.3V and 5V domains
Procurement Notes
Verify the specific suffix 'E4Q' against official IDT documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints, as packaging variations may exist within the 74LVC series. Confirm RoHS status and moisture sensitivity level requirements for your assembly process before ordering.
Selection Notes
Select this component when an octal register with tri-state capability is required in low-voltage designs. Its 5V tolerance makes it suitable for mixed-voltage environments without additional level shifters. Consider the operating voltage range and speed requirements relative to system clock frequencies to ensure timing margins are met.
Part Context
This part belongs to the 74LVC family of advanced high-speed CMOS logic devices. It is functionally equivalent to other manufacturers' 74LVC374 variants but carries IDT's specific manufacturing specifications. The 'AE4Q' designation typically indicates a specific package configuration and quality tier defined by Integrated Device Technology.
Replacement Considerations
Cross-reference with NXP or ON Semiconductor 74LVC374 parts for pin-compatible alternatives. Verify that substitute components match the 1.65V-3.6V operating range and 5V input tolerance specifications to maintain system integrity.
