The KS74HCTLS245N is an octal bus transceiver with 3-state outputs from Samsung Semiconductor. This device is designed for asynchronous two-way communication between data buses. It features a direction control input (DIR) that determines the direction of data flow, and an output enable input (OE) that controls whether the outputs are enabled or in a high-impedance state. The 'HCTLS245 combines the high speed of the HCT family with the low power consumption of CMOS technology.

Applications

Additional Details

The KS74HCTLS245N consists of eight transceivers with inverting outputs. When the output enable (OE) input is low, the outputs are enabled, allowing data to pass through the transceiver. When OE is high, the outputs are in a high-impedance state, effectively disconnecting the device from the bus. The direction control (DIR) input determines whether data flows from A to B or from B to A. The device is available in a 20-pin DIP package, making it suitable for through-hole mounting on PCBs. It operates over the industrial temperature range of -40°C to +85°C. Its high noise immunity and robust design make it a reliable choice for demanding applications. The HCTLS logic family provides TTL-compatible input thresholds with CMOS power consumption levels.
