74VHC244TTR Overview

It utilizes a neat 20-TSSOP (0.173, 4.40mm Width) package. A logical driver like this one is packaged using an external packaging called Tape & Reel (TR). You can find this bus transceiver in the Surface Mount mounting format. Typical Buffer, Non-Inverting logic integrated circuits with a broad application range. An operating voltage of 2V~5.5V is applied to the ethernet transceiver, and it is powered by that voltage. A voltage buffer of this type operates at -40°C~85°C TA ambient temperature. There are 8mA 8mA logic state output currents of it in the high and low logic states. The outputs can be grouped into 3-State. It uses all 2 elements. 74VHC series transceivers are part of this device. 20 terminations are provided by this buffer. Supply voltage must be 3.3V. There is a AHC/VHC family part that is attached to this electronic component. With the electrical component, there are 20 pins. In total, it can be used for Surface Mount different purposes. The cable has 20 pins. Transceiver with 2 ports. Each element utilizes 4 bits. Other related electrical parts can also be found on 74VHC244. It's a type of Bus Driver/Transceivers, specifically. Electronic part 4?A is used in a quiescent stateA TAPE AND REEL package is usually sold with it. Depending on the transceiver, a voltage of 2V is required to supply the device with electricity. It is capable of producing 3 signal lines at a time. There are 8 inputs on it. Buffer ICs are controlled by ENABLE LOW control technology during startup.
