74LVT574

74LVT574, 74LVTH574 — Low Voltage Octal D-Type Flip-Flop with 3-STATE Outputs January 2008 74LVT574, 74LVTH574 Low Voltage Octal D-Type Flip-Flop with 3-STATE Outputs Features ■ Input and output interface capability to systems at 5V VCC ■ 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 –32mA/+64mA ■ Functionally compatible with the 74 series 574 ■ Latch-up performance exceeds 500mA ■ ESD performance: – Human-body model > 2000V – Machine model > 200V – Charged-device model > 1000V General Description 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) VCC 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.
