  • PCA9519 4channel level transla

    The PCA9519 is a 4-channel level translating I2C-bus/SMBus repeater that enables theprocessor low voltage 2-wire serial bus to interface with standard I2C-bus or SMBus I/O.While retaining all the operating modes and features of the I2C-bus system during thelevel shifts, it also permits extension of ...

  • Replacement of NXP PCA9518 wit

    The outputs of the PCA9518 are immediately available as soon as there is a voltage present on thesupply >~1V and behave as described above. The power-on reset of the PCA9518A keeps the outputsturned off during power-up and maintains the high impedance of the outputs throughout the power-upcycle. The ...

  • DUAL RS-232 DRIVER RECEIVER WI

    The TRS232E is a dual driver/receiver that includes a capacitive voltage generator to supply TIA/RS-232-Fvoltage levels from a single 5-V supply. Each receiver converts TIA/RS-232-F inputs to 5-V TTL/CMOS levels.This receiver has a typical threshold of 1.3 V, a typical hysteresis of 0.5 V, and can a ...

  • DUAL DIGITAL ISOLATORS

    The ISO7220 and ISO7221 are dual-channel digital isolators. To facilitate PCB layout, the channels are orientedin the same direction in the ISO7220 and in opposite directions in the ISO7221. These devices have a logic inputand output buffer separated by TI’s silicon-dioxide (SiO2) isolation barrier ...

  • PCA954X家庭的I C SMBus多路复用器与开关

    The Philips family of Multiplexers and Switches consists of bi-directional translating switches controlled via the I2C or SMBus to fan out an upstream SCL/SDA pair to 2, 4 or 8 downstream channels of SCx/SDx pairs. The Multiplexers allow only one downstream channel to be selected at a time, while th ...

  • Input Signal Rise and Fall Tim

    All inputs of the C16x family have Schmitt-Trigger input characteristics. These Schmitt-Triggers are intended to always provide proper internal low and high levels, even if anundefined voltage level (between TTL-VIL and TTL-VIH) is externally applied to the pin.The hysteresis of these inputs, howeve ...
