74LVTH374: Low Voltage Octal D-Type Flip-Flop with 3-STATE Outputs

The LVT374 and LVTH374 are high-speed, low-power octal D-type flip-flops 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 LVTH374 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) VCC applications, but with the capability to provide a TTL interface to a 5V environment. The LVT374 and LVTH374 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining low power dissipation.

Features

• Input and output interface capability to systems at 5V V_CC
• Bus-Hold data inputs eliminate the need for external pull-up resistors to hold unused inputs (74LVTH374), also available without bushold feature (74LVT374).
• 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 374
• Latch-up performance exceeds 500 mA
• ESD performance:Human-body model > 2000VMachine model > 200VCharged-device model > 1000V
