Product Overview: 74LVTH16646MEA from ON Semiconductor

The 74LVTH16646MEA is a high-performance, Low-Voltage BiCMOS Technology (LVT) 16-bit bus transceiver and register designed for 3.3V VCC operation, but with the capability to provide a 5V tolerant interface to a 5V bus. Manufactured by ON Semiconductor, a leading innovator in the semiconductor industry, this product is part of their 74LVTH range, which is known for its robust performance and versatility.

This integrated circuit is designed to be used in applications requiring high-speed and low power consumption. It is particularly suitable for driving bus lines or buffer memory address registers in systems that require high-speed, low-noise operation. The 74LVTH16646MEA features two separate 16-bit bus transceiver sections, each with 3-state outputs. The device allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic levels at the direction-control (DIR) inputs.

The input and output voltage levels of the 74LVTH16646MEA are compatible with LVTTL and LVCMOS technologies, making it a versatile choice for interfacing with different logic families. The device also provides a flow-through architecture that optimizes the PCB layout, while the power-off disable feature ensures no excessive current draw when the device is powered down.

Key features of the 74LVTH16646MEA include:

• 16-bit bi-directional transceiver with 3-state outputs
• Separate control logic for each section
• 5V tolerant inputs and outputs for interfacing with 5V logic
• Support for live insertion and withdrawal (partial-power-down mode)
• Bus Hold on data inputs to eliminate the need for external pull-up/pull-down resistors
• Latch-up performance exceeds 500mA per JESD78, Class II

The 74LVTH16646MEA is available in a 48-lead SSOP package, providing a compact footprint for space-constrained applications. Its operating temperature range is from -40°C to +85°C, making it suitable for industrial applications with harsh environmental conditions.

ON Semiconductor's commitment to quality ensures that the 74LVTH16646MEA meets the stringent requirements of the latest industrial standards. With its excellent performance and reliability, the 74LVTH16646MEA is an ideal choice for designers looking to implement high-speed data bus communications or memory interfacing in their next-generation electronic systems.
