SN74LS245N Description

Short technical summary and product information.

The SN74LS245N is an 8-bit (octal) bus transceiver designed for bidirectional asynchronous communication between data buses. Manufactured by Texas Instruments, this logic IC features non-inverting outputs with 3-state control, allowing multiple outputs to share a common bus line. It operates over a supply voltage range of 4.75V to 5.25V and can sink or source up to 24mA (per output). The typical propagation delay from port to port is 8ns, making it suitable for high-speed data transfer in TTL logic systems. The device is housed in a 20-pin DIP (0.300" width) package with through-hole mounting, ideal for prototyping and legacy system designs. The SN74LS245N is rated for commercial temperature range (0°C to 70°C). It is part of the 74LS logic family, known for its low-power Schottky TTL technology.
