概述

Description

TMUX1248DCKR is a Texas Instruments TMUX family device: a 12-channel analog multiplexer/demultiplexer. It has one common output and 12 selectable inputs, chosen by a 4‑bit address (A0–A3). It’s typically a single-supply, CMOS analog switch with low on-resistance, low leakage, and break-before-make behavior to avoid shorting channels. Common uses include multiplexing signals from several sensors to one ADC or routing signals in test/measurement hardware. The DCKR suffix designates the packaging variant (e.g., Tape & Reel). How to use: provide VCC and GND, connect the 12 inputs to your signals, connect the common output to the next stage (e.g., an ADC), and drive the select pins to choose which input is connected. Consider source impedance, switching time, charge injection, and leakage for your signal. For exact electrical specs, pinout, and timing, consult the TMUX1248 datasheet on TI’s site.

Features

TMUX1248DCKR features (concise):
- 8-channel, 1-of-8 analog multiplexer/demultiplexer (one common port connected to any one of eight inputs)
- Control via 3 address lines plus an enable (break-before-make switching)
- Wide, single-supply operation with rail-to-rail analog I/O
- Low on-resistance and low leakage with low charge injection
- Suitable for signal routing in data acquisition, instrumentation, and test apps
- DCKR package (tape-and-reel) for automated assembly
Note: Exact electrical specs (RON, leakage, voltage range) are device datasheet dependent.

Package

TMUX1248DCKR uses TI’s DCK package, i.e., a TSSOP-16 package, in a reel (R = Tape & Reel).

Pinout

Pin count: 16 pins (DCKR package).
Function: TMUX1248DCKR is an 8-channel analog multiplexer/demultiplexer (8:1) with a single common I/O, controlled by three select lines (A, B, C) and an enable.

Manufacturer

The TMUX1248DCKR is manufactured by Texas Instruments (TI). TI is an American multinational technology company that designs and manufactures semiconductors and related components, specializing in analog and embedded processing devices.
