LTC-5337G

The LTC-5337G is a display module equipped with seven segmented alphanumeric characters as well as LED indicators. It is manufactured by Linear Technology and is primarily used for inventory management and data logging tasks, in which seven characters need to be displayed at a time. The module is embedded in an 18-pin DIP package and produces four digits of LED characters divided into two sections.The module is powered by a single 5 V supply and operates at a temperature range of -20 °C to +70 °C. The on-board current sink drivers allow up to 7.5 mA per segment and 7 bits of hexadecimal data are required to drive each segment of the displayed character. With this module, it is also possible to regulate the brightness of the display by varying the duty cycle of the display segments.The input of the LTC-5337G is composed of two sections: the four HEX input bits and the three decimal point input bits. The four HEX inputs control the display of each segment, while the three decimal point input bits indicate bit 3 position, bit 0 position and the ODP (Overall Display Option) bit, respectively. The ODP bit allows for multiple display applications, such as the simultaneous display of multiple alphanumeric characters, symbols, or from a single seven segmented character.The output is formed of 16 LEDs, which are divided into two segments separated by two LEDs for the two decimal points. The first two LEDs are used to display the four bit data, while the remaining LEDs are used to display the three bit data.The basic working principle of the LTC-5337G module is quite simple. The input hexadecimal data is given to the module which then determines the segments of the character to be displayed. The output of the module is then the LEDs that are activated that yield the specified character.To sum up, the LTC-5337G is an advanced display module ideal for applications that require data logging and inventory management. The module features an easy to understand working principle, short setup time, efficient power usage and long operational life. It is an advanced LED character and numeric display module that provides reliable and cost effective results.
