概述

Description

TMUX1308BQBR is a Texas Instruments 8-channel analog multiplexer/demultiplexer. It lets you route one of eight analog inputs to a single common output (or vice versa) under control of a 3-bit select input. This is useful for multiplexing sensors to one ADC or routing a signal to multiple destinations in a compact form.
Key points:
- Single-supply operation: typically 1.65 V to 5.5 V
- Low on-resistance path and low leakage when off
- Break-before-make switching to avoid shorting signals
- Suitable for data acquisition, sensor multiplexing, audio routing, and portable devices
BQBR indicates RoHS-compliant, lead-free, and tape-and-reel packaging; exact package and pinout depend on the specific option—check the datasheet for electrical specs, pinout, and packaging details. For precise figures, refer to the TMUX1308 datasheet.

Features

Here are the typical features of the TMUX1308BQBR (8-channel analog multiplexer):
- 8-channel analog multiplexer/demultiplexer (1-of-8) with a common I/O
- Enable input to disconnect all channels (high-impedance when disabled)
- 3-bit select address (S0–S2) for channel selection
- Break-before-make switching to reduce glitches
- Single-supply operation (generally 1.65 V to 5.5 V, rail-to-rail I/O)
- Low on-resistance (RON) and low leakage (high off-isolation)
- Fast switching with low charge injection
- Small 8-pin package (BQBR) with robust ESD/overvoltage characteristics
Note: Refer to the exact datasheet for precise voltage ranges, RON, leakage, and timing specs for your specific operating conditions.

Package

TMUX1308BQBR comes in an 8-pin VSSOP (Very Small Outline Package).

Pinout

- Pin count: 16 pins (TSSOP-16/VSSOP-16 style package).
- Function: 8-channel analog multiplexer/demultiplexer. Routes one of I0–I7 to a common output (COM) under control of a 3-bit select (S0–S2); includes an enable to tri-state all switches when asserted. Power pins (VCC, GND) plus any NCs as per package.

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: Texas Instruments is an American multinational technology company that designs and manufactures semiconductors and integrated circuits, including analog, digital, microcontrollers, sensors, and wireless products. It is one of the world's largest semiconductor companies.
