CD74HC646M Overview
Logical driver uses a neat 24-SOIC (0.295, 7.50mm Width) package. Tube external packaging. Available in Surface Mount. Voltage buffer adopts Transceiver, Non-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. 24 terminations with different functions. Buffer IC reuqires a supply voltage of 4.5V. Transceiver shares the HC/UH family's comprehensive benefits and features. 24 pins are set with the electric part. Buffer IC is suitable for Surface Mount applications. Logical driver has 24 pins. Enhanced with 2 ports. You can search "74HC646" for other related electrical components. Specifically, digital transciever is a kind of Bus Driver/Transceivers. The digital buffer starts up under INDEPENDENT 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. The fundamental operation of logical driver is based on 8 circuits. Logical driver adapts POSITIVE EDGE trigger.
