74LS45 DIP BCD to Decimal Decoder Driver IC (16-Pin TTL Logic IC)

The 74LS45 DIP BCD to Decimal Decoder Driver IC is a TTL logic integrated circuit that converts a 4-bit Binary Coded Decimal (BCD) input into one of ten active-low decimal outputs with open collector driver capability. Housed in a 16-pin Dual Inline Package (DIP), it is built using Low Power Schottky (LS) TTL technology for high-speed operation and low power consumption.

The open collector outputs provide high current sinking capability and require external pull-up resistors for proper operation. The 74LS45 is widely used in decimal decoding, LED and lamp driving, indicator panels, industrial control systems, digital displays, and embedded electronics.
