3.3 -V ABT八路透明D类锁存器具有三态输出 3.3-V ABT OCTAL TRANSPARENT D-TYPE LATCHES WITH 3-STATE OUTPUTS
description/ordering information
These octal latches are designed specifically for low-voltage 3.3-V VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.
The eight latches of the ’LVTH573 devices are transparent D-type latches. While the latch-enable LE input is high, the Q outputs follow the data D inputs. When LE is taken low, the Q outputs are latched at the logic levels set up at the D inputs.
• Support Mixed-Mode Signal Operation 5-V Input and Output Voltages With 3.3-V VCC
• Support Unregulated Battery Operation Down to 2.7 V
• Typical VOLP Output Ground Bounce
<0.8 V at VCC = 3.3 V, TA = 25°C
• Ioff and Power-Up 3-State Support Hot Insertion
• Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors
• Latch-Up Performance Exceeds 500 mA Per JESD 17
• ESD Protection Exceeds JESD 22
− 2000-V Human-Body Model A114-A
