Product Overview: NXP 74HCT4514D

The NXP 74HCT4514D is a high-performance integrated circuit that belongs to the 74HCT family, known for its compatibility with TTL (Transistor-Transistor Logic). This particular chip is a 4-to-16 line decoder/demultiplexer with input latches. It features a 16-bit memory that is ideal for applications requiring the selection or activation of multiple outputs.

Key Features

• Logic Type: Decoder / Demultiplexer
• Input Type: Latched
• Output Current: 25 mA
• Propagation Delay Time: 19 ns
• Supply Voltage Range: 4.5V to 5.5V
• Operating Temperature Range: -40°C to +125°C
• Mounting Type: Surface Mount
• Package / Case: SOIC-24

Functional Description

The 74HCT4514D is designed with 4 binary input lines that are latched on the positive-going edge of the latch enable (LE) signal. The device converts the 4-bit input to one of 16 mutually exclusive outputs when the enable (E) input is LOW. The demultiplexing function is performed by using the E input as data input and the 4-bit select input as addressing which then determines which one of the 16 outputs will carry a HIGH level.

Applications

This versatile decoder/demultiplexer can be used in a wide range of applications, including:

• Memory address decoding
• Data routing
• Control signal generation
• PLD programming
• LED display driving
