SN74LS645-1NE4 Product Details

SN74LS645-1NE4 Overview


Using a neat PDIP package, it works well. A total of 1 elements are used. A logic device such as this has 20 terminations with different functions. Supply voltage is 5V. Family LS includes the buffer IC . There are 20 pins set with the electric component. Through Hole applications are possible with digital buffer. The connector has 20 pins. A total of 2 ports are available on this bus transceiver. It is recommended to use a power supply that has 5V volts. The TUBE package is generally sold. This electronic part should be operated safely and steadily in a circuit by applying 5V supply voltage. A total of 8 efficient bits are included as part of this electronic component. Featuring WITH DIRECTION CONTROL, automotive buffer better serves the needs of users. 8 channels ensure high-quality communication with this logic IC. As low as 0°C can be used to operate itTemperatures above 70°C are not recommended for it to operate. Low-level output mode produces 15mA. Electronic parts operating in high-level output mode may conduct -15mA of current. This buffer should be run at a minimum voltage of 4.75V if it is to function properly. With respect to its maximum supply voltage, it is rated at 5.25V. This bus transceiver is referred to as BUS TRANSCEIVER logic. A COMMON CONTROL-control voltage buffer starts up.
