SN74LV244A

SN74LV244A SCLS383Q – SEPTEMBER 1997 – REVISED MARCH 2023 SN74LV244A Octal Buffers and Drivers With 3-State Outputs 1 Features VCC operation of 2 V to 5.5 V Maximum tpd of 6.5 ns at 5 V Typical VOLP (output ground bounce) <0.8 V at VCC = 3.3 V, TA = 25°C Typical VOHV (output VOH undershoot) >2.3 V at VCC = 3.3 V, TA = 25°C Support mixed-mode voltage operation on all ports Ioff supports partial-power-down mode operation Latch-up performance exceeds 250-mA per JESD 17 2 Applications Servers and network switches LED displays Telecom infrastructure Motor-drive control boards 1 1OE 3 Description The SN74LV244A octal buffers and line drivers are designed for 2-V to 5.5-V VCC operation. The SN74LV244A devices are designed specifically to improve both performance and density of the 3state memory address drivers, clock drivers, and busoriented receivers and transmitters. These devices are organized as two 4-bit line drivers with separate output-enable (OE) inputs.
