Description and Introduction
Octal bus transceiver; 3-state The 74AHCT245D is a high-speed Si-gate CMOS device manufactured by NXP Semiconductors (PHI). It is an octal bus transceiver with 3-state outputs, designed for asynchronous communication between data buses. The device features non-inverting outputs and bidirectional data flow controlled by the direction (DIR) input. The output enable (OE) input disables both the A and B ports, placing them in a high-impedance state. The 74AHCT245D operates with a supply voltage range of 4.5V to 5.5V and is compatible with TTL levels. It has a typical propagation delay of 5.5 ns and a maximum power dissipation of 500 mW. The device is available in a 20-pin SOIC package.
