74LVTH374

74LVT374, 74LVTH374 — Low Voltage Octal D-Type Flip-Flop with 3-STATE Outputs January 2008 74LVT374, 74LVTH374 Low Voltage Octal D-Type Flip-Flop with 3-STATE Outputs Features ■ Input and output interface capability to systems at 5V VCC ■ 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 –32mA/+64mA ■ Functionally compatible with the 74 series 374 ■ Latch-up performance exceeds 500mA ■ ESD performance: – Human-body model > 2000V – Machine model > 200V – Charged-device model > 1000V General Description 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.
