SN74LVC1G74 Single Positive-Edge-Triggered D-Type Flip-Flop with Clear and Preset 1 Features 3 Description
This single positive-edge-triggered D-type flip-flop is • Available in the Texas Instruments 1 designed for 1.65-V to 5.5-V VCC operation. NanoFree™ Package • Supports 5-V V NanoFree™ package technology is a major CC Operation breakthrough in IC packaging concepts, using the die • Inputs Accept Voltages to 5.5 V as the package. • Supports Down Translation to VCC A low level at the preset (PRE) or clear (CLR) input • Max tpd of 5.9 ns at 3.3 V sets or resets the outputs, regardless of the levels of • Low Power Consumption, 10-µA Max ICC the other inputs. When PRE and CLR are inactive • ±24-mA Output Drive at 3.3 V (high), data at the data (D) input meeting the setup time requirements is transferred to the outputs on the • Typical VOLP (Output Ground Bounce) positive-going edge of the clock pulse. Clock < 0.8 V at VCC = 3.3 V, TA = 25°C triggering occurs at a voltage level and is not related • Typical VOHV (Output VOH Undershoot) directly to the rise time of the clock pulse. Following > 2 V at VCC = 3.3 V, TA = 25°C the hold-time interval, data at the D input can be • I changed without affecting the levels at the outputs. off Supports Live Insertion, Partial-Power-Down Mode, and Back-Drive Protection This device is fully specified for partial-power-down • Latch-Up Performance Exceeds 100 mA Per applications using Ioff. The Ioff circuitry disables the JESD 78, Class II outputs, preventing damaging current backflow through the device when it is powered down. • ESD Protection Exceeds JESD 22 – 2000-V Human-Body Model
