SN74LS640DBR Overview
Logical driver uses a neat 20-SSOP (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 4.75V~5.25V. Qualified to operate within 0°C~70°C TA. The high and low logic state output current of logical driver is 15mA 24mA. Logical driver can deal with 3-State output (s). All of the 1 elements are put into use. Digital buffer is one of the 74LS series devices. 28 terminations with different functions. Buffer IC reuqires a supply voltage of 5V. This electronic part belongs to the LS family of parts. 28 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 "74LS640" for other related electrical components. The digital buffer starts up under COMMON CONTROL control technology. It is generally sold in TR package. To run the part safely and stably in a circuit, 5V recommends users apply 5V on the logical driver.
