SN74LVTH18504APMR Description

Short technical summary and product information.

The SN74LVTH18504APMR is a 20-bit universal bus transceiver from Texas Instruments, part of their SCOPE and Widebus families. This device utilizes a state-of-the-art 3.3-V ABT design, supporting mixed-mode signal operation with 5-V input and output voltages while operating at a 3.3-V VCC. It can also support unregulated battery operation down to 2.7 V.

This transceiver combines D-type latches and D-type flip-flops for flexible operation in transparent, latched, or clocked modes. It features bus hold on data inputs, eliminating the need for external pullup or pulldown resistors. The B-port outputs have equivalent 25-series resistors, removing the need for external resistors. The device is compatible with the IEEE Std 1149.1-1990 (JTAG) test access port and boundary-scan architecture.

Packaged in a 64-pin Plastic Thin Quad Flat (LQFP) package with a 0.5-mm center-to-center pitch, the SN74LVTH18504APMR is designed for surface mounting. It operates within a temperature range of -40°C to 85°C and is supplied in a standard package quantity of 1000 units on tape and reel.
