SN74AS640DW Overview
Logical driver uses a neat 20-SOIC (0.295, 7.50mm Width) package. Tube external packaging. Available in Surface Mount. Voltage buffer adopts Transceiver, 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 64mA. 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. 20 terminations with different functions. Buffer IC reuqires a supply voltage of 5V. AS family part. 20 pins are set with the electric part. Buffer IC is suitable for Surface Mount applications. Logical driver has 20 pins. Enhanced with 2 ports. The bus transceiver employs 8 bits for each element. You can search "74AS640" 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. It is recommended to use a 5V power supply. To supply the device, a minimum voltage of 4.5V is a must. Logical driver features WITH DIRECTION CONTROL to better serve the need.
