CD74HC640E Overview
Logical driver uses a neat 20-DIP (0.300, 7.62mm) package. Tube external packaging. Available in Through Hole. Voltage buffer adopts Transceiver, Inverting logic prototype. Buffer IC is fed with a voltage of 2V~6V. Qualified to operate within -55°C~125°C TA. The high and low logic state output current of logical driver is 7.8mA 7.8mA. Logical driver can deal with 3-State output (s). All of the 1 elements are put into use. Digital buffer is one of the 74HC series devices. 20 terminations with different functions. Buffer IC reuqires a supply voltage of 4.5V. This buffer driver is part of the HC/UH family of parts. 20 pins are set with the electric part. Buffer IC is suitable for Through Hole applications. Logical driver has 20 pins. Enhanced with 2 ports. You can search "74HC640" for other related electrical components. Specifically, digital transciever is a kind of Bus Driver/Transceivers. The digital buffer starts up under COMMON CONTROL control technology. In quiescent state, the electronic part uses 8μA. It is recommended to use a 2/6V power supply. To supply the device, a minimum voltage of 2V is a must. 8 bits are included within the electrical component. Logical driver features WITH DIRECTION CONTROL to better serve the need. 8 channels for high quality communication.
