SN74HC245N (74HC245) Logic chip
Description:
The SN74HC245N features eight bidirectional data lines (A1 to A8 and B1 to B8) with direction control pins (DIR) to enable data flow from either bus A to bus B or vice versa. It operates at high speed and is compatible with TTL (Transistor-Transistor Logic) inputs, making it versatile for use in a wide range of digital logic applications requiring data exchange between different subsystems.
