• Reduced Component Count: Integrated decoder/demultiplexer function reduces the number of discrete components required.

Additional Details

The HD14514BP decodes a 4-bit binary input address into one of 16 mutually exclusive output lines. The device includes input latches to store the address data. The latches are enabled by a latch enable (LE) input. When LE is high, the outputs follow the input address. When LE is low, the address data is latched and the outputs remain stable. The device is housed in a standard 24-pin DIP package. The operating temperature range is typically -40°C to +85°C.
