74ACT520SJ

The 74ACT520SJ is a high-speed TTL compatible CMOS logic device. It consists of two 1-of-4 multiplexers and one quad 2-input NAND gate. The device is a 5-V only part and is designed for compatibility with standard TTL logic families. The device has low power consumption, and is available in 20-pin packages.

The 74ACT520SJ is primarily used in applications such as digital multiplexing, data communication systems and telecommunications. The device is also suitable for other comparator and logic applications.

The 74ACT520SJ multiplexers have four select inputs, four data inputs, one control input and one data output. The multiplexers select one of the four data inputs depending on the combination of the select inputs. The multiplexers operate in a synchronous mode and the control input is used to enable or disable the multiplexers. The output of the multiplexers is the selected data input.

The quad 2-input NAND gate has two inputs and one output. The output of the NAND gate is the opposite logic level of the input. The NAND gate can be used for various logic operations such as AND, OR, NOT, etc.

The 74ACT520SJ is characterized for operation over the full military temperature range of -55°C to 125°C. The device is specified for a supply voltage of 4.5 V to 5.5 V and a standby power consumption of less than 5 µW.

The 74ACT520SJ is a cost effective solution for applications such as multiplexers and logic in telecommunications, data communication systems, and digital multiplexing. The device offers a high speed, low power consumption, and is available in 20-pin packages.
