The SN54LVC573A octal transparent D-type latch is designed for 2.7-V to 3.6-V VCC operation, and the SN74LVC573A octal transparent D-type latch is designed for 1.65-V to 3.6-V VCC operation. These devices feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, input/output (I/O) ports, bidirectional bus drivers, and working registers.

  • Operate From 1.65 V to 3.6 V
  • Inputs Accept Voltages to 5.5 V
  • Max tpd of 6.9 ns at 3.3 V
  • Typical VOLP (Output Ground Bounce)
    < 0.8 V at VCC = 3.3 V, TA = 25°C
  • Typical VOHV (Output VOH Undershoot)
    > 2 V at VCC = 3.3 V, TA = 25°C
  • Support Mixed-Mode Signal Operation on All Ports (5-V Input/Output Voltage With 3.3-V VCC)
  • Ioff Supports Live Insertion, Partial Power Down Mode, and Back Drive Protection
  • 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)
