The LB-302 series were designed to meet the need for multi-digit numeric displays. These two-digit LED numeric displays have a character height of 7.62 mm. The LB-302 series were designed to meet the ...

Eight-pin microcontrollers offer numerous peripheral features. However, the maximum number of I/O pins available is often limited to six, since two pins would be required for the chip's power supply.

This circuit uses two National Semiconductor LM3914 dot/bar-display-driver ICs to implement a two-digit, 0 to 5V LED voltmeter that mimics a subranging flash ADC. An LED bar graph comprising five LEDs ...

The Soviet-era 490IP1 LED. The digit is a mere 2.5 mm in height. Pictured with the Texas Instruments TIL306. [image: industrialalchemy.org] It’s easy to assume that older components will be less ...
