philips 74HC245 74HCT245 Octal bus tranceiver 3-state handbook
The 74HC245 and 74HCT245 are high-speed Si-gate CMOS devices that are pin compatible with Low-Power Schottky TTL (LSTTL). These octal transceivers feature non-inverting 3-state bus compatible outputs in both send and receive directions, making them suitable for bidirectional data transfer applications. The devices include an output enable input (OE) for cascading and a send/receive input (DIR) for direction control.
