SN74LVTH322374
3.3-V ABT 32-BIT EDGE-TRIGGERED D-TYPE
FLIP-FLOP WITH 3-STATE OUTPUTS
SCBS754C – MARCH 2002 – REVISED NOVEMBER 2006
• Bus Hold on Data Inputs Eliminates the Need
for External Pullup/Pulldown Resistors
• Distributed V_CC and GND Pins Minimize
High-Speed Switching Noise
• Flow-Through Architecture Optimizes PCB
Layout
• Latch-Up Performance Exceeds 500 mA Per
JESD 17
• ESD Protection Exceeds JESD 22
– 2000-V Human-Body Model (A114-A)
– 200-V Machine Model (A115-A)
