Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to 74HC245. 74HC 245 is a eight (8) bit transceiver. It has three (3) output states. 74HC-245 is designed for a-synchronous transfer of data between different data buses. The external timing requirement can be reduced by the implementation of control function. You should also have a look at Introduction to 74HC595. There are two internal amplifiers in 74HS 245. They are named as A and B. Data is transferred from A amplifier to B amplifier and vice versa. Hence two way communication is done in 74HC-245. This communication depends upon the logic level on the direction control input (DIR). Out enable pin (OE) is used to enable and disable the device depending upon the requirements of the task. 74HC-245 has several amazing features e.g. low input current, large input voltage ranges, low power consumption etc. A lot of real life applications are associated with 74HC-245, a few of which are servers, electronic points of sale, telecom infrastructures, network switches, personal computers, notebooks, wearable health devices etc. The further detail about 74HC-245 will be given later in this article.

Introduction to 74HC245

74HC245 is basically and 8-bit transceiver. It has 3 output states. The data can be transferred in both directions depending upon the logic level at direction control (DIR). You can enable and disable the device from the output enable (OE) pin. low power consumption, wide voltage range, low input current are the major features associated with 74HC-245. 74HC 245 is mostly used in personal computers, servers, wearable health devices, fitness devices, network switches, electronic points of sale etc. 74HC 245 is shown in the figure given below.
