74LCXH16244MTD

Overview

The 74LCXH16244MTD is a low-voltage 16-bit buffer and line driver manufactured by onsemi. It operates within a supply voltage range of 2 V to 3.6 V, supporting 1.8 V, 2.5 V, and 3.3 V systems. The device features 3-state outputs and includes active bus hold circuitry to maintain valid logic states for unused or floating inputs. It provides high drive capability with ±24 mA output current at 3.0 V and ±18 mA at 2.3 V. The component supports live insertion and withdrawal and offers ESD protection exceeding 2000 V via the human body model.

Feature Summary

• Active bus hold functionality prevents undefined states in floating inputs
• Supports live insertion and withdrawal operations
• High drive strength with ±24 mA output current capability
• Low static supply current reduces overall system power consumption

Applications

• High-speed data buffering in low-voltage digital systems
• Line driving for memory and storage interfaces
• Bus holding applications requiring stable input states
• Live hot-swap signal conditioning circuits

Procurement Notes

Verify the specific suffix MTD corresponds to the TSSOP-48 package configuration required for your design. Confirm RoHS compliance status and lead-free characteristics against the latest manufacturer datasheet revision. Ensure voltage levels match the 2 V to 3.6 V operating range. Check for any obsolescence notices or lifecycle changes directly from onsemi before finalizing procurement plans.

Selection Notes

Select this component when designing 16-bit wide buffers requiring low-voltage operation between 2 V and 3.6 V. It is suitable for applications needing high drive current and protection against floating inputs via bus hold. Consider alternatives if higher voltage tolerance beyond 3.6 V is required or if different pin counts are necessary. Verify thermal performance requirements for the TSSOP-48 package in your specific layout.

Part Context

This part belongs to the LCXH family of low-voltage CMOS logic devices from onsemi. It serves as a non-inverting buffer designed for high-speed, low-power applications. The LCXH series typically targets modern portable and battery-operated equipment where reduced supply voltages are standard. It complements other bus transceivers and drivers within the same logical product line.

Replacement Considerations

The 74VCXH16244 is a documented similar part number offering comparable low-voltage 16-bit buffering functions. Verify pinout compatibility and electrical specifications such as propagation delay and drive current before substitution. Ensure the replacement supports the same voltage ranges and package types.
