Product Overview: MC74HCT245ADWR2G by ON Semiconductor

The MC74HCT245ADWR2G is a high-performance, integrated circuit designed and manufactured by ON Semiconductor, a leading provider in the semiconductor industry. This device is part of the HCT (High-speed CMOS, TTL compatible) family and serves as an octal 3-state non-inverting bus transceiver, designed to be used in two-way asynchronous communication between data buses. The transceiver allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction control (DIR) input.

The device's outputs can be put in a high-impedance state, effectively disconnecting the bus lines, by utilizing the Output Enable (OE) input. This feature is particularly useful in applications that require multiple peripherals to share a common bus line without interfering with one another, such as microprocessor or microcontroller systems.

Key Features:

• Logic Type: CMOS
• Number of Channels: 8
• Output Type: 3-State
• Supply Voltage Range: 4.5V to 5.5V
• Operating Temperature Range: -55°C to +125°C
• Package / Case: SOIC-20W
• Mounting Type: Surface Mount

The MC74HCT245ADWR2G is TTL compatible at the input and operates at a voltage range from 4.5V to 5.5V, making it suitable for interfacing with 5V TTL systems while maintaining the low power consumption of CMOS technology. This device is capable of driving heavy loads, up to 15 LSTTL loads, and features balanced propagation delays and transition times, which are essential for maintaining signal integrity in high-speed data communication.

ON Semiconductor has packaged the MC74HCT245ADWR2G in a 20-pin SOIC wide-body (SOIC-20W), which is ideal for surface-mounted technology (SMT). The product is available in tape and reel, ensuring it is ready for automated assembly processes. It is designed to operate over an extended temperature range of -55°C to +125°C, making it robust for industrial applications.

The MC74HCT245ADWR2G transceiver is a crucial component for designers looking to ensure reliable data transfer while maintaining high-speed operation and is an excellent choice for use in a wide range of applications, including computing, networking, and telecommunications.
