NEXPERIA 74HC245D Octal Tri-State Bus Transceiver, SOIC-20, 2V to 6V

The NEXPERIA 74HC245D is a high-performance octal (8-bit) bus transceiver integrated circuit in a compact 20-pin SOIC package. Designed for bidirectional data transfer, it features non-inverting three-state outputs compatible with both sending and receiving directions, making it a versatile component for bus interface applications.

This device is constructed using high-speed silicon-gate CMOS technology, offering the benefit of low power consumption while maintaining full pin compatibility with Low-Power Schottky TTL (LSTTL) logic families. This compatibility ensures easy integration into a wide range of existing and new digital system designs.

A key feature is the output enable (OE) input, which provides easy cascading of multiple devices and effective isolation of control buses. The direction control (DIR) input dictates whether the bus lines are configured as inputs or outputs, allowing for flexible data flow management. The three-state outputs can be placed in a high-impedance state, permitting multiple devices to share a common bus without interference.

The transceiver operates from a wide supply voltage range of 2V to 6V, supporting various logic level standards. It is built to comply with the JEDEC standard JESD 7A and includes Electrostatic Discharge (ESD) protection, enhancing its reliability in handling and operation. With an extended ambient operating temperature range from -40°C to +125°C, it is suitable for demanding industrial and automotive environments.

With its robust design and standardised specifications, the 74HC245D is a reliable, industry-standard solution for buffering and driving data buses in complex digital systems.
