74LVTH16245MTDX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74LVTH16245MTDX is a low-voltage 16-bit bidirectional transceiver with 3-STATE outputs, designed for bus-oriented applications. It features byte-controlled operation with separate control inputs for each byte, which can be shorted for full 16-bit functionality. The device utilizes an advanced BiCMOS technology to achieve high-speed operation similar to 5V ABT while maintaining low power dissipation. It supports live insertion/extraction and provides glitch-free bus loading during power-up/down transitions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs
• Input and output interface capability to systems at 5V VCC
• Power Up/Down high impedance provides glitch-free bus loading
• Outputs source/sink ±16mA/±24mA

Buffers, Drivers, Receivers, Transceivers Applications

• Bus oriented applications
• Systems requiring 3.3V VCC with TTL interface to 5V environment
• Live insertion/extraction scenarios

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering code suffix 'X' indicates Tape and Reel packaging as per datasheet notes. Confirm package type matches MTD48 (48-Lead Thin Shrink Small Outline Package). Check RoHS compliance status in official documentation. Ensure ESD handling procedures are followed due to charged-device model sensitivity.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit bidirectional transceiver with bushold feature is required for 3.3V systems interfacing with 5V environments. Consider the TSSOP-48 package for surface mount applications. Verify compatibility with existing logic families and ensure adequate power supply decoupling for high-speed operation.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74LVT/LVTH series of low-voltage transceivers. It is functionally compatible with the 74 series 16245 but optimized for lower voltage operation. The LVTH variant specifically includes bushold inputs, distinguishing it from the standard LVT version. Manufactured using BiCMOS technology for performance and efficiency.
