ICN74HC245

Logic control

Description
The ICN74HC245 is a high-speed Si-gate CMOS device and is pin compatible with Low-Power Schottky TTL (LSTTL).
The ICN74HC245 are high-speed octal three-state bidirectional transceivers intended for two-way asynchronous communication between data buses. The ICN74HC245 allow data transmission of the B bus or from the B bus to the A bus. The logic level atthe direction input (DIR) determines the direction. The output enable input(OE\), when high, puts the I/O ports in the high-impedance state.
