Overview
The Fairchild Semiconductor 74VCX162374MTD is a low-voltage, 16-bit D-type flip-flop featuring 3-state outputs. It operates within a supply voltage range of 1.65V to 3.6V and utilizes TSSOP-48 packaging. The device provides high-speed performance with a propagation delay of 9.6 ns and supports output currents up to ±12 mA at 3.0V. Designed for surface-mount applications, it functions reliably across an industrial temperature range of -40°C to +85°C.
Feature Summary
- Supports bidirectional data transfer via 3-state outputs
- Enables direct interface between 1.8V and 3.3V logic systems
- Provides latchup protection exceeding 300 mA
Applications
- Asynchronous communication interfaces
- Data bus buffering
- Memory address latching
Procurement Notes
Verify the specific suffix 'MTD' against current manufacturer documentation to confirm package type and availability status. Cross-reference the component with onsemi resources as Fairchild Semiconductor operations have been acquired. Ensure that the requested quantity aligns with current production lifecycles and lead times provided by authorized distributors.
Selection Notes
Select this component when designing systems requiring translation between different voltage domains without external level shifters. Consider the 16-bit width for parallel data paths and the 3-state capability for bus sharing. Evaluate the TSSOP-48 footprint against PCB space constraints and thermal requirements compared to alternative packages like FBGA.
Part Context
This part belongs to the VCX series of low-voltage logic devices designed for portable and battery-operated applications. It complements other translators and buffers in the family, offering high integration density. The series is characterized by reduced power consumption and compatibility with standard CMOS logic levels.
Replacement Considerations
Check for functional equivalents such as the 74VCXH162374 or 74VCX16245 from onsemi/Fairchild. Verify pinout compatibility and electrical specifications before substitution.
