The DM7427N is an IC (Integrated Circuit) component commonly used in digital circuits for its functional capabilities. It is a quad 2-input NAND gate with open collector outputs. Here are some of its key features and an overview of its functionality:
1. Integrated Circuit Type: DM7427N belongs to the DM74xx series, which are high-speed, low-power TTL (Transistor-Transistor Logic) integrated circuits.
2. Quad 2-Input NAND Gate: It consists of four separate NAND gates, each having two input terminals that can accept binary inputs (0 or 1). The NAND operation outputs a logical 0 if both inputs are logical 1; otherwise, it outputs a logical 1.
3. Open Collector Outputs: The DM7427N has open collector outputs, meaning that it can only sink current and cannot actively drive outputs high. It requires an external pull-up resistor to provide a logical 1 output level.
4. Pin Configuration: The IC is housed in a 14-pin dual in-line package (DIP). The pins are labeled as inputs (A, B, C, D), outputs (Y), and power supply (VCC and GND).
5. Operating Voltage Range: It operates within a VCC voltage range of 4.75V to 5.25V, making it suitable for use in 5V systems
