Flip-Flops for Operation in Transparent,
Latched, or Clocked Mode
D Bus Hold on Data Inputs Eliminates the
Need for External Pullup/Pulldown
Resistors
D B-Port Outputs of SN74LVTH182512 Device
Has Equivalent 25-Ω Series Resistors, So
No External Resistors Are Required
D SCOPE  Instruction Set
− IEEE Std 1149.1-1990 Required
Instructions and Optional CLAMP and
HIGHZ
− Parallel-Signature Analysis at Inputs
− Pseudo-Random Pattern Generation
From Outputs
− Sample Inputs/Toggle Outputs
− Binary Count From Outputs
− Device Identification
− Even-Parity Opcodes
† Component qualification in accordance with JEDEC and industry
standards to ensure reliable operation over an extended
temperature range. This includes, but is not limited to, Highly
Accelerated Stress Test (HAST) or biased 85/85, temperature
cycle, autoclave or unbiased HAST, electromigration, bond
intermetallic life, and mold compound life. Such qualification
testing should not be viewed as justifying use of this component
beyond specified performance and environmental limits.
D Compatible With the IEEE Std 1149.1-1990
