74LCX16244MEA

Overview

The onsemi 74LCX16244MEA is a low-voltage 16-bit buffer and line driver featuring non-inverting logic with three-state outputs. Designed for memory address driving, clock distribution, and bus-oriented transmitter/receiver applications, it operates within a supply voltage range of 2.3V to 3.6V. The device incorporates 5V tolerant inputs and outputs, allowing safe interfacing with 5V systems while powered by lower voltages. It supports live insertion and withdrawal, ensuring system reliability during hot-swapping operations.

Feature Summary

• Provides sixteen non-inverting buffers with independent three-state control for each nibble
• Features 5V tolerant inputs and outputs for seamless compatibility with 5V TTL logic devices
• Supports live insertion and withdrawal capabilities to facilitate real-time hardware maintenance

Applications

• Memory address drivers in computer systems
• Clock signal distribution networks
• Bus-oriented transmitter and receiver circuits

Procurement Notes

Verify the specific suffix 'MEA' against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your manufacturing process. Cross-reference the datasheet revision date to confirm electrical characteristics match your design constraints before finalizing procurement orders.

Selection Notes

Select this component when designing low-voltage systems requiring high-speed data buffering with 5V interface compatibility. The 16-bit configuration reduces board space compared to multiple 8-bit alternatives. Consider the three-state output capability for managing shared bus architectures where multiple devices must drive the same lines without contention.

Part Context

This part belongs to the LCX family of low-voltage CMOS logic devices from onsemi. The LCX series is engineered for high performance at reduced supply voltages, offering faster switching speeds and lower power consumption compared to older LVX or LVC families. It serves as a standard solution for modern digital interfaces requiring robust signal integrity.

Replacement Considerations

Compatible substitutes include the Fairchild/ON Semiconductor 74LCX16244G and National Semiconductor 54LCX16244. Verify pinout compatibility and electrical parameters such as propagation delay and output drive current before substituting.
