คุณลักษณะ

• Standard Logic 74LS Series BCD to 7 segment decoder/driver.
• When a 7 segment LED indicator is connected to the output, numbers up to 0~9 corresponding to 4 bit 10 digit input (0000~1001) are displayed.
• It also responds to the input of 10 or more 10 digits (1010 ~1111 in 4 bits), but does not display as 16 digits of A to F.
• Since this is an active low open collector output, it is compatible with an anode common type indicator that lights up when a segment is connected to ground.
• The output current is also large and can usually drive the LED display directly, but a current limiting resistor is required between each segment and the open collector output.
• The current limiting resistor cannot be shared on the common terminal side.
