概述

Description

SN74LVC1G66DSFR is TI’s ultra‑small, single 2→1 data multiplexer. It has two data inputs (D0, D1), one select input (S), and one output (Y). Operation: Y = D0 when S = 0; Y = D1 when S = 1 (non‑inverting). It runs from 1.65 V to 3.6 V, making it suitable for mixed‑voltage, portable electronics.
Package/variant: DSFR denotes a tiny 6‑pin package (SC‑70/SOT‑23‑6 style) with Pb‑free/RoHS compliance.
Key features: low power consumption, fast propagation, and Ioff support for partial‑power‑down devices. Suitable for signal routing, level shifting, or simple data selection between two sources in MCU/SoC designs.
Pinout (typical): Vcc, GND, D0, D1, S, Y. For exact electrical specs (propagation delay, input/output characteristics, and recommended operating conditions) consult the TI datasheet.

Features

Here are the key features of SN74LVC1G66DSFR:
- Single 2:1 multiplexer (two data inputs A, B; one select input S; one output Y)
- Supply voltage: 1.65 V to 5.5 V (LVC family)
- Very small 6-pin DSFR package (SC-70/SOT-353 family footprint)
- Low static and dynamic power; CMOS technology
- Wide operating temperature range (-40°C to 125°C)
- TTL/CMOS input thresholds compatible with the Vcc range
- Lead-free, RoHS-compliant package
- ESD protection suitable for typical handling in logic circuits
- Suitable for compact data-routing and signal-selection applications
Note: For exact electrical specs (propagation delay, input/output characteristics, and exact ESD ratings), consult the TI datasheet.

Package

SC-70-6 (6-pin) package.

Pinout

Pin count: 6 pins (SOT-23-6/SC-70 package).
Function: SN74LVC1G66DSFR is a single 2-input multiplexer (2:1 data selector). It selects between inputs A and B based on the select input S to produce output Y, with VCC and GND pins included.

Manufacturer

Manufacturer: Texas Instruments (TI). TI is an American multinational semiconductor company that designs and manufactures analog and digital integrated circuits and embedded processing products.

Application

Single 2:1 multiplexer. Applications: data-path routing and bus multiplexing in microcontrollers, DSPs, and FPGA interfaces; voltage-domain bridging in mixed-supply designs (1.65–3.6 V); compact, low-power signal selection for portable devices; sensor/ADC/DAC signal routing and communication buses; suitable for automotive and industrial systems requiring a small package.
