SN74LVTH322374
3.3ĆV ABT 32ĆBIT EDGEĆTRIGGERED DĆTYPE FLIPĆFLOP
WITH 3ĆSTATE OUTPUTS
SCBS754B − MARCH 2002 − REVISED SEPTEMBER 2003
D Member of the Texas Instruments
Widebus+  Family
D Output Ports Have Equivalent 22-Ω Series
Resistors, So No External Resistors Are
Required
D Supports Mixed-Mode Signal Operation
(5-V Input and Output Voltages With
3.3-V V_CC )
D Supports Unregulated Battery Operation
Down to 2.7 V
D Typical V_OLP (Output Ground Bounce)
<0.8 V at V_CC = 3.3 V, T_A = 25°C
D I_off and Power-Up 3-State Support Hot
Insertion
D Bus Hold on Data Inputs Eliminates the
Need for External Pullup/Pulldown
Resistors
D Distributed V_CC and GND Pins Minimize
High-Speed Switching Noise
D Flow-Through Architecture Optimizes PCB
Layout
D Latch-Up Performance Exceeds 500 mA Per
JESD 17
D ESD Protection Exceeds JESD 22
− 2000-V Human-Body Model (A114-A)
− 200-V Machine Model (A115-A)
