SN74LVTH18646APM Description

Short technical summary and product information.

The SN74LVTH18646APM from Texas Instruments is an 18-bit scan test device featuring transceivers and registers. This specialty logic IC is part of the Texas Instruments SCOPE and Widebus families, designed for testability and mixed-signal operation.

Key electrical characteristics include a supply voltage range of 2.7V to 3.6V, supporting unregulated battery operation down to 2.7V. The device operates across a temperature range of -40°C to 85°C, making it suitable for various environmental conditions.

This device supports IEEE Std 1149.1-1990 (JTAG) boundary scan architecture. It includes D-type flip-flops and control circuitry for multiplexed transmission of stored and real-time data. Bus hold on data inputs eliminates the need for external pullup/pulldown resistors. The B-port outputs have equivalent 25-series resistors, negating the need for external resistors.

The SN74LVTH18646APM is packaged in a 64-pin LQFP (10x10 mm) and is designed for surface mount applications. The standard package quantity is 160 units, supplied in a JEDEC TRAY.
