SN74AS638AN 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 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 - 64mA; 15mA 64mA. Logical driver can deal with Open Collector, Push-Pull 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. Electronic parts from the AS family are used in this part. 20 pins are set with the electric part. Enhanced with 2 ports. The bus transceiver employs 8 bits for each element. To supply the device, a minimum voltage of 4.5V is a must. Logical driver features WITH DIRECTION CONTROL to better serve the need.
