SN74AUCH16244DGGR

The SN74AUCH16244DGGR from Texas Instruments is a 16-bit buffer/driver featuring 3-state outputs, optimized for 1.8-V operation and 3.6-V I/O tolerance. This device supports mixed-mode signal operation, allowing for seamless integration in systems with varying voltage levels. It is designed to improve the performance and density of memory address drivers, clock drivers, and bus-oriented receivers and transmitters.

This buffer/driver operates from 0.8-V to 2.7-V VCC, with specific optimization for 1.65-V to 1.95-V VCC operation. Key electrical characteristics include a maximum propagation delay of 1.8 ns at 1.8 V and an output drive of ±8 mA at 1.8 V. It also features low power consumption with a maximum ICC of 20 µA and supports partial-power-down mode operation. Bus hold on data inputs eliminates the need for external pullup/pulldown resistors.

The SN74AUCH16244DGGR is housed in a 48-TSSOP package, suitable for surface mounting. It operates within a temperature range of -40°C to 85°C. The device can be configured as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer, providing flexibility in design. Its symmetrical active-low output-enable (OE) inputs ensure proper control over the 3-state outputs.
