HSTL_ II_DCI, HSTL_ IV_DCI, HSTL_ II_DCI_18, HSTL_ IV_DCI_18

HSTL_II_DCI provides on-chip split thevenin termination powered from V
an equivalent termination voltage of V
to V
links.

HSTL_ II_T_DCI, HSTL_ II_T_DCI_18

HSTL_ II_T_DCI and HSTL_ II_T_DCI_18 provide on-chip split-thevenin termination
powered from V
standards are 3-stated. When not 3-stated, these two standards do not have termination.

DIFF_HSTL_ II, DIFF_HSTL_II_18

Differential HSTL class II pairs complimentary single-ended HSTL_II type drivers with a
differential receiver. Differential HSTL class II is intended to be used in bidirectional links.
Differential HSTL can also be used for differential clock and DQS signals in memory
interface designs.

DIFF_HSTL_II_DCI, DIFF_HSTL_II_DCI_18

Differential HSTL class II pairs complimentary single-ended HSTL_II type drivers with a
differential receiver, including on-chip differential split-thevenin termination. Differential
HSTL class II is intended to be used in bidirectional links. Differential HSTL can also be
used for differential clock and DQS signals in memory interface designs.

DIFF_HSTL_I, DIFF_HSTL_I_18

Differential HSTL class I pairs complimentary single-ended HSTL_I type drivers with a
differential receiver. Differential HSTL class I is intended to be used in unidirectional links.

DIFF_HSTL_I_DCI, DIFF_HSTL_I_DCI_18

Differential HSTL class I pairs complimentary single-ended HSTL_I type drivers with a
differential receiver, including on-chip differential split-thevenin termination. Differential
HSTL class I is intended to be used in unidirectional links.
