SN74AVCBH164245VR: 16-Bit Dual-Supply Bus Transceiver with Configurable Voltage Translation and 3-State Outputs

The SN74AVCBH164245VR from Texas Instruments is a versatile, high-speed, 16-bit dual-supply bus transceiver designed to address the need for efficient voltage level translation in multi-voltage systems. This integrated circuit is ideal for applications that require the transfer of data between two buses of different voltage levels, such as between a core processor and peripheral devices.

Featuring configurable voltage translation without the need for an external direction control signal, this device can translate bidirectionally between any of the voltage nodes (1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V). The SN74AVCBH164245VR operates with two distinct supply voltages, V_CCA and V_CCB, which allow translation from a lower to a higher voltage and vice versa, making it extremely flexible for modern mixed-voltage systems.

The device offers 3-state outputs, which can be put into a high-impedance state, thus allowing for disconnection from the bus or for connection to multiple devices on the same bus. This is particularly useful in applications such as memory interfacing, data multiplexing, and in systems that require a high degree of modularity.

With an optimized design for signal integrity, the SN74AVCBH164245VR ensures minimal propagation delay and skew, which is critical for maintaining data coherency in high-speed communication systems. The robust construction of the device also provides for latch-up performance that exceeds 100 mA per JESD 78, Class II, and it is specified for the –40°C to 85°C industrial temperature range.

Available in a compact 48-pin TSSOP (Thin Shrink Small Outline Package) with the orderable part number SN74AVCBH164245VR, this transceiver is a practical solution for designers looking to simplify their interface logic while maintaining high performance and reliability.
