SN74ALVC164245

The SN74ALVC164245 is a 16-bit, dual-octal, noninverting bus transceiver designed for asynchronous communication between data buses. It features two separate supply rails, allowing for flexible voltage translation. The A port supports VCCA at 2.5 V and 3.3 V, while the B port supports VCCB at 3.3 V and 5 V. This enables translation from a 2.5-V to a 3.3-V environment, or from a 3.3-V to a 5-V environment, and vice versa.

Key electrical characteristics include a maximum propagation delay of 5.8 ns at 3.3 V and an output drive current of ±24 mA at 3.3 V. The control circuitry, including direction (DIR) and output-enable (OE) inputs, is powered by VCCA. For reliable operation during power up or power down, the output-enable input should be tied to VCC through a pullup resistor.

This transceiver is suitable for various applications such as electronic points of sale, printers, motor drives, wireless and telecom infrastructures, and wearable health and fitness devices. It is available in multiple package types, including TSSOP, SSOP, and BGA MICROSTAR JUNIOR, with body sizes varying by package.

The SN74ALVC164245 is a member of the Texas Instruments Widebus™ family, known for high-speed performance and advanced features. Latch-up performance exceeds 250 mA per JESD 17.
