The DM74LS245N from ON Semiconductor is an octal bus transceiver designed for asynchronous two-way communication between data buses. This device features 3-STATE outputs that can drive bus lines directly and PNP inputs that reduce DC loading. Hysteresis at the bus inputs improves noise margins.
Key electrical characteristics include a supply voltage range of 4.75V to 5.25V, with typical propagation delay times of 8 ns and enable/disable times of 17 ns. It supports sink current of 24 mA and source current of -15 mA. The operating temperature range is from 0°C to 70°C (TA).
The DM74LS245N is housed in a 20-lead PDIP package, suitable for through-hole mounting. The device allows data transmission from the A Bus to the B Bus or vice versa, controlled by the DIR input. The enable input (G) can be used to disable the device, effectively isolating the buses.
This transceiver is suitable for applications requiring bidirectional data transfer between two buses where control over data flow and isolation is necessary.
