MC74HC245ADWG

MC74HC245ADWG Description

The MC74HC245ADWG from onsemi is a high-performance 8-bit bidirectional transceiver belonging to the 74HC series, designed for surface-mount applications. Operating within a 2V to 6V supply voltage range, it is optimized for low-power, high-speed logic interfacing while maintaining robust signal integrity. Packaged in a 20-SOIC (Tube), this transceiver is RoHS3 compliant and adheres to REACH unaffected standards, making it suitable for environmentally conscious designs. With a current output capability of 7.8mA (both high and low), it ensures reliable signal transmission in mixed-voltage systems. Its Moisture Sensitivity Level (MSL 3) ensures stability for up to 168 hours in humid environments.

MC74HC245ADWG Features

• Bidirectional 8-bit transceiver with non-inverting outputs for seamless data flow control.
• Wide operating voltage (2V–6V), compatible with TTL and CMOS logic levels.
• High output current (7.8mA) for driving capacitive loads or multiple inputs.
• Low power consumption typical of HC logic family, ideal for battery-operated devices.
• 3-state outputs allow bus isolation, reducing contention in shared bus architectures.
• Robust ESD protection and MSL 3 rating enhance reliability in industrial environments.
• Surface-mount 20-SOIC package saves board space while enabling automated assembly.
