Texas Instruments 74LV244A
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.FEATURES
●1 2-V to 5.5-V VCC Operation● Max 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
● ESD Protection Exceeds JESD 22 – 2000-V Human-Body Model (A114-A) – 200-V Machine Model (A115-A) – 1000-V Charged-Device Model (C101) 2
