ON Semiconductor 74VCX164245MTD: A Versatile Bidirectional Transceiver

The 74VCX164245MTD from ON Semiconductor is a high-performance, low-voltage, bidirectional transceiver designed for asynchronous communication between data buses. This integrated circuit (IC) is ideal for voltage translation applications where a 3.3V to 5V bidirectional level shifter is required. The device allows for seamless data transfer between a 16-bit bus and a central processor or another data bus with different voltage levels.

Featuring 16 non-inverting bidirectional buffers, the 74VCX164245MTD is organized into two sets of eight channels each, with separate output-enable (OE) inputs for each byte. This allows for greater flexibility in control and bus management. The inputs can be connected to a 3.3V or 2.5V supply, and they are 5V tolerant, which ensures compatibility with mixed-voltage systems.

The device operates at -40°C to +85°C, making it suitable for industrial applications where temperature resilience is crucial. It is housed in a 48-lead thin shrink small outline package (TSSOP), which is conducive to space-constrained applications while also providing adequate heat dissipation.

Key features of the 74VCX164245MTD include:

• Low voltage operation: 1.65V to 3.6V VCC supply operation
• High-speed data transfer: capable of handling speeds up to 240 Mbps (120 MHz)
• 5V tolerant inputs and outputs for interfacing with 5V logic levels
• Power-off high impedance inputs and outputs
• Support for live insertion and withdrawal (partial power-down mode)
• Low quiescent current consumption, which is ideal for power-sensitive applications
• Static Drive (IOH/IOL): ±24 mA @ 3.0V VCC
• Latch-up performance exceeds 300 mA
• ESD protection exceeds JESD 22

The 74VCX164245MTD is a reliable choice for system designers looking to bridge the gap between different voltage domains while maintaining signal integrity and speed. Whether used in consumer electronics, networking equipment, or industrial control systems, this transceiver from ON Semiconductor is engineered to provide a robust, high-speed data transmission solution.
