SN74ALS638A-1NSR Overview
Logical driver uses a neat 20-SOIC (0.209, 5.30mm Width) package. Tape & Reel (TR) 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 - 24mA; 15mA 24mA. 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 74ALS series devices. 20 terminations with different functions. Buffer IC reuqires a supply voltage of 5V. This logical driver is a member of the ALS family. 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. You can search "74ALS638" 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. It is generally sold in TAPE AND REEL package. 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. The fundamental operation of logical driver is based on 8 circuits.
