SN74LVTH18514DGGR

Overview

The SN74LVTH18514DGGR is a 3.3-V ABT scan test device featuring a 20-bit universal bus transceiver, manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 3.6 V and supports LVTTL input and output levels. The component provides a low-level output current of 64 mA and a high-level output current of -32 mA, with a propagation delay of 6.8 ns. It is housed in a 64-pin TSSOP package and functions as a non-inverting, three-state bus transceiver suitable for surface-mount installation.

Feature Summary

• Integrates a 20-bit universal bus transceiver designed specifically for scan test applications
• Supports LVTTL logic levels with three-state outputs for efficient bus management
• Utilizes BiCMOS technology to deliver high drive capability and fast switching speeds

Applications
