SN74LVCH16245 16-Bit Bus Transceiver with 3-State Outputs

The SN74LVCH16245 device from Texas Instruments is a 16-bit non-inverting bus transceiver designed to facilitate bidirectional communication between two data buses. It features 3-state outputs that enable direct connection to a bus-organized system. This high-speed transceiver is part of the LVCH family, which operates at a voltage range of 2.7V to 3.6V, making it suitable for interfacing with low-voltage logic without the need for external level shifters.

With its low-voltage and high-speed characteristics, the SN74LVCH16245 is optimized for use in applications that require efficient data transfer while maintaining low power consumption. The device is particularly well-suited for memory interconnects, data switching in servers, and communication systems where high-speed data transfer is crucial.

Key Features:

• Wide Bus Interface: 16-bit bus width enables simultaneous transmission of 16 data lines.
• Bi-Directional Data Flow: With direction control, the data flow can be tailored to the needs of the system, either from A to B or B to A.
• 3-State Outputs: The outputs can be placed in a high-impedance state, effectively disconnecting them from the bus, which is useful in multiplexed bus applications.
• Low Operational Voltage: Supports a supply voltage range from 2.7V to 3.6V, which is compatible with 3.3V logic levels.
• High-Speed Operation: Capable of operating at high speeds, ensuring quick data transmission between buses.
• Control Pins: Includes output enable (OE) and direction control (DIR) pins for flexible control over data transmission and output states.
• Latch-Up Performance: Exceeds 250 mA per JESD 17, providing robustness against latch-up events.
• ESD Protection: Incorporates protection against electrostatic discharge, enhancing the durability of the device in sensitive environments.

The SN74LVCH16245 is available in a variety of packages, including the TSSOP (Thin Shrink Small Outline Package) and the DB (Gull Wing) form factors, providing flexibility for different PCB layouts and design considerations. Its compatibility with JEDEC standard no. 7A ensures that it meets the necessary industry specifications for electronic components.

Whether you are designing a new system or upgrading an existing one, the SN74LVCH16245 from Texas Instruments represents a reliable and efficient solution for high-speed, low-voltage digital interfacing.
