ON Semiconductor 74LVTH16652MTD Product Overview

The 74LVTH16652MTD is a high-performance, low-voltage 16-bit registered transceiver with 3-state outputs from ON Semiconductor. This integrated circuit is designed to be used in applications that require high-speed bidirectional communication between two buses. The device is part of ON Semiconductor's LVTH family, which is known for its low-voltage operation and tolerance to higher system voltages.

Constructed with an advanced BiCMOS technology, the 74LVTH16652MTD offers optimal performance with a 3.3V power supply while maintaining 5V tolerant inputs and outputs. This makes it suitable for interfacing with 5V systems, thus providing a bridge between different voltage domains in a mixed 3.3V/5V system environment.

The device features two separate 16-bit bus transceivers with 3-state outputs, each of which can operate independently. The transceivers are capable of transmitting data from the A bus to the B bus or vice versa depending on the logic levels at the direction control (DIR) inputs. The output enable (OE) inputs can be used to place the I/O ports in high-impedance states, which is particularly useful in multiplexed bus applications where output contention may occur.

Key features of the 74LVTH16652MTD include:

• 16-bit bidirectional transceiver with 3-state outputs
• Operates from a 3.3V supply with 5V tolerant inputs and outputs
• High drive capability (-32mA IOH, 64mA IOL)
• Power-off high-impedance I/O
• Bus hold on data inputs to eliminate the need for external pull-up/pull-down resistors
• Flow-through pinout for ease of printed circuit board trace routing
• Latch-up performance exceeds 500mA per JESD78 Class II Level A
• ESD protection exceeds JESD 22

The 74LVTH16652MTD is packaged in a 56-pin TSSOP (Thin Shrink Small Outline Package) which is designed for space-saving and reduced weight in applications where board real estate is at a premium. This device is ideal for use in telecommunications, computing, and industrial applications where low-voltage, high-speed, and bidirectional data flow control is essential.

With its robust design and compatibility with mixed-voltage environments, the 74LVTH16652MTD from ON Semiconductor is a versatile solution for modern digital systems requiring reliable and efficient data transfer capabilities.
