74HC244N,652 Overview
Logical driver uses a neat 20-DIP (0.300, 7.62mm) package. Tube external packaging. Available in Through Hole. Voltage buffer adopts Buffer, Non-Inverting logic prototype. Buffer IC is fed with a voltage of 2V~6V. Qualified to operate within -40°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 2 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 5V. This logical driver is a member of the HC/UH family. 20 pins are set with the electric part. Enhanced with 2 ports. The bus transceiver employs 4 bits for each element. You can search "74HC244" for other related electrical components. Specifically, digital transciever is a kind of Bus Driver/Transceivers. The digital buffer starts up under ENABLE LOW control technology. It is generally sold in BULK PACK package. To supply the device, a minimum voltage of 2V is a must.
