The LVT574 and LVTH574 are high-speed, low-power octal D-type flip-flop featuring separate D-type inputs for each flip-flop and 3-STATE outputs for bus-oriented applications. A buffered Clock (CP) and Output Enable (OE#) are common to all flip-flops.

The LVTH574 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.

These octal flip-flops are designed for low-voltage (3.3V) V_CC applications, but with the capability to provide a TTL interface to a 5V environment. The LVT574 and LVTH574 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining a low power dissipation.

• Input and output interface capability to systems at 5V V_CC
• Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs (74LVTH574), also available without bushold feature (74LVT574)
• Live insertion/extraction permitted
• Power Up/Down high impedance provides glitch-free bus loading
• Outputs source/sink -32 mA/+64 mA
• Functionally compatible with the 74 series 574
• Latch-up performance exceeds 500 mA
• ESD performance:

  Human-body model > 2000V

  Machine model > 200V

  Charged-device model > 1000V
