SN74AS646DW 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 4.5V~5.5V. Qualified to operate within 0°C~70°C TA. The high and low logic state output current of logical driver is 15mA 48mA. Logical driver can deal with 3-State output (s). All of the 1 elements are put into use. Digital buffer is one of the 74AS series devices. 24 terminations with different functions. Buffer IC reuqires a supply voltage of 5V. Family AS includes the buffer IC . 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 "74AS646" 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. It is recommended to use a 5V power supply. To run the part safely and stably in a circuit, 5V recommends users apply 5V on the logical driver. 8 bits are included within the electrical component. Logical driver features DIRECTION CONTROL; SELECT INPUT FOR MULTIPLEXED TRANSMISSION OF REGISTERED OR REAL TIME DATA to better serve the need. 8 channels for high quality communication. Logical driver adapts POSITIVE EDGE trigger.
