Description for the TIC12400

The TIC12400 is an advanced Multiple Switch Detection Interface (MSDI) device designed to detect external switch statuses. The TIC12400 supports 24 direct inputs, with 10 inputs configurable to monitor digital I/O switches. 6 wetting current settings can be programmed for each input to support different application scenarios. The TIC12400 features an integrated 10-bit ADC to monitor multi-position analog switches and a comparator to monitor digital switches independently of the MCU. The device supports wake-up operation on all switch inputs to eliminate the need to keep the MCU active continuously, thus reducing power consumption of the system. The TIC12400 supports 2 modes of operations: continuous and polling mode. In continuous mode, wetting current is supplied continuously. In polling mode, wetting current is turned on periodically to sample the input status based on a programmable timer, thus the system power consumption is significantly reduced. The TIC12400 also offers various fault detection and diagnostic features for improved system robustness.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
