The Texas Instruments SN74AUCH244RGYR is an octal buffer/driver designed for versatile operation across a voltage range of 0.8V to 2.7V, with specific optimization for 1.65V to 1.95V VCC. This device features two 4-bit line drivers, each controlled by a separate output-enable (OE) input. When OE is low, data passes from the A inputs to the Y outputs; when OE is high, the outputs enter a high-impedance state.
Key electrical characteristics include a maximum propagation delay of 1.9 ns at 1.8V and low power consumption with a maximum ICC of 20 µA. The device provides ±8 mA output drive at 1.8V and includes active bus-hold circuitry on data inputs, eliminating the need for external pullup or pulldown resistors. It also supports partial-power-down applications with Ioff circuitry to prevent damaging current backflow.
This buffer/driver is housed in a 20-VQFN (3.5x4.5) surface-mount package. It is specified for operation over a temperature range of -40°C to 85°C (TA). ESD protection exceeds JESD 22 standards, including 2000V for the human-body model, 200V for the machine model, and 1000V for the charged-device model. Latch-up performance exceeds 100 mA per JESD 78, Class II.
