SN74AVCAH164245GR Description

Short technical summary and product information.

The SN74AVCAH164245GR from Texas Instruments is a 16-bit, dual-octal, noninverting bus transceiver. It features two separate configurable power-supply rails, allowing each port to operate from 1.4V to 3.6V. This enables universal low-voltage bidirectional translation between 1.5V, 1.8V, 2.5V, and 3.3V voltage nodes.

 

This transceiver is designed for asynchronous communication between data buses. Data can be transmitted from the A bus to the B bus or vice versa, controlled by the direction-control (DIR) input. The output-enable (OE) input can disable the outputs, effectively isolating the buses. Active bus-hold circuitry is included to maintain the state of unused or floating data inputs.

 

The device supports partial power-down mode operation using Ioff circuitry, which disables outputs to prevent damaging current backflow when powered down. If either VCC input is at GND, both ports enter a high-impedance state. ESD protection exceeds JESD 22 standards, including Human-Body Model (2000V), Machine Model (200V), and Charged-Device Model (1000V).

 

Packaged in a 48-TSSOP, the SN74AVCAH164245GR is suitable for surface mounting and operates within a temperature range of -40°C to 85°C.
