The DM74LS245N is a 3-state octal bus transceiver designed for asynchronous two-way communication between data buses. It features bi-directional data transmission, allowing data to flow from the A Bus to the B Bus or vice versa, controlled by the direction control (DIR) input. The device can be disabled via the enable input (G), effectively isolating the buses. This transceiver is housed in a 20-lead plastic dual-in-line package (PDIP) and operates with a supply voltage of 4.75V to 5.25V. It has a typical propagation delay of 8 ns and enable/disable times of 17 ns. The output can sink up to 24 mA and source up to -15 mA, making it suitable for driving bus lines directly. The input hysteresis improves noise margins, enhancing reliability in data transmission. The operating temperature range is from 0°C to +70°C, with a storage temperature range of -65°C to +150°C. This product is appropriate for applications requiring efficient data bus management and isolation.
