SN74LS244DWRE4 Product Details

SN74LS244DWRE4 Overview


An interesting SOIC package is used. The 2 elements all play a role. Logic device with 20 different terminations. There is a requirement for 5V of supply voltage. This electronic part belongs to the LS family of parts. This electric component comes with 20 pins. Surface Mount applications can be used with digital buffer. A 20-pin connector is used. An enhanced bus transceiver with 2 ports is available. Each element employs 4 bits. An example of a Bus Driver/Transceivers type is this. It uses 27mA when quiescent. An electrical supply with 5V is recommended. There is usually a TR package available. As low as 0°C is not a problem for it to operate. An ambient temperature of no more than 70°C should be used. The low-level output mode outputs 15mA. It is possible that the electronic part may conduct 24mA current in high-level output mode. It is strongly recommended that you use at least a voltage of 4.75V when operating this buffer. There is a maximum supply voltage rating of 5.25V. As a result of its 8 line level input capability, the buffer IC is more cost-effective for the transmission of signals. The BUS DRIVER logic bus transceiver is known as such. Voltage buffers using ENABLE LOW control start up automatically.
