74LVTH16244MEA

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74LVTH16244MEA is a low-voltage 16-bit buffer and line driver featuring 3-STATE outputs, housed in a 48-lead Small Shrink Outline Package (SSOP). Designed for 3.3V VCC applications with TTL interface capability to 5V environments, it utilizes advanced BiCMOS technology for high-speed operation and low power dissipation. The device includes bushold data inputs to eliminate external pull-up resistors for unused lines. It supports live insertion/extraction and provides glitch-free bus loading during power up/down cycles.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs
• Supports live insertion and extraction operations
• Provides glitch-free bus loading through power up/down high impedance states
• Interfaces directly between 3.3V systems and 5V environments

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address drivers
• Clock drivers
• Bus-oriented transmitter/receiver circuits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches the 48-lead SSOP designation MS48A. Ensure compatibility with existing board designs regarding voltage levels and pin configurations before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit buffering with 3-STATE control in a compact SSOP footprint. It is suitable for applications needing direct interfacing between 3.3V logic and 5V tolerant environments without additional level shifting components.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74LVT16244/LVTH16244 family of low-voltage 16-bit buffers. While functionally similar to other 74-series logic devices, it is specifically optimized for low-voltage operation with enhanced drive capabilities and specific input features like bushold found in the LVTH variant.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct functional substitutes include the 74LVT16244MEA (without bushold) and 74LVTH16244MTD (TSSOP package). Verify pinout compatibility and electrical characteristics before substitution.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the difference between 74LVT16244 and 74LVTH16244?
