DUAL Transceiver, Non-Inverting 4.5V~5.5V 3-State Buffers 74HCT Series 74HCT645 20 Pins 8 Bit per Element 6mA 6mA 20-SOIC (0.209, 5.30mm Width)
SN74HCT645NSRE4 Overview
20-SOIC (0.209, 5.30mm Width) packages are used to implement buffer. It is packaged in the Tape & Reel (TR) external packaging type for this voltage buffer. This digital buffer is available in the Surface Mount mount. There are a variety of applications for Transceiver, Non-Inverting logic integrated circuits. The logic IC is powered by 4.5V~5.5V. An ambient temperature of -40°C~85°C TA is suitable for this logical driver. There is a 6mA 6mA output current in the high and low logic states. 3-State outputs are supported. Transceiver uses all 1 elements. This is a network transceiver from the 74HCT series. 20 terminations are present in this ethernet transceiver, each of which serves a different purpose. A supply voltage of 5V is required. In the HCT family, the electric component belongs. The electric component includes 20 pins. There are Surface Mount applications for it. There are 20 pins on it. 2 ports have been added to this bus transceiver. Each element is represented by 8 bits. 74HCT645 has other related electronic components that you can search for. The power supply should be 5V . TAPE AND REEL packages are generally used. There must be a minimum voltage of 4.5V in order to supply the digital buffer. To better serve the needs, it features WITH DIRECTION CONTROL. Logical drivers powered by COMMON CONTROL control technology start up automatically.
