74AC245TTR Overview

Buffer uses a neat 20-TSSOP (0.173, 4.40mm Width) package. This logic IC uses the Tape & Reel (TR) external packaging. This digital buffer is available in the Surface Mount mount. This is a typical Transceiver, Non-Inverting logic integrated circuit that sees a broad field of applications. This network transceiver is fed with a supply voltage of 2V~6V. This automotive buffer is qualified to operate within the ambient temperature of -55°C~125°C TA. The high and low logic state output current of It is 24mA 24mA. Digital buffer can deal with 3-State output (s). All of the 1 elements are put into use. It is one of the 74AC series transceivers. 20 terminations with different functions. It reuqires a supply voltage of 3.3V. This electronic component belongs to the AC family. 20 pins are set with the electrical part. It is suitable for Surface Mount applications. It has 20 pins. Enhanced with 2 ports. You can search 74AC245 for other related electronic component. Specifically, It is a kind of Bus Driver/Transceivers. It is recommended to use a 3.3/5V power supply. It is generally sold in TAPE AND REEL package. To supply the digital buffer, a minimum voltage of 2V is a must. 8 efficient bits are included within the network transceiver. This network transceiver has 8 channels for high quality communication. COMMON CONTROL control technology starts up the logical driver.
