Note 1.
DC parameters are guaranteed after thermal equilibrium has been established.
Note 2.
The LVL input determines the voltage switching threshold that differentiates logic high from logic low for the V
T inputs S0, S1, S2,
DELAY_SEL, and CINV. LVL may be driven to V
CC, but this is not useful, as the VT inputs could then not get high enough to reliably indicate
logic high. Also, as shown in Figure 3, the LVL input internally clamps at V
TCL. If LVL is left unconnected, the VT inputs will switch at about the
maximum of

Note 3.
V
T inputs are S0, S1, S2, DELAY_SEL, and CINV.
Note 4.
V
SW is the threshold switching voltage. It is equal to the voltage at the LVL pin, when this voltage is above VTCL (max). VSW is some value
between V
TCL (min) and VTCL (max) when the Voltage at the LVL pin is below VTCL (max).
Note 5.
V
IST is the voltage difference needed to guarantee a stable logic level. Logic high must be at least VIST above VSW. Logic low must be at most
V
IST below VSW. Thus, the minimum input swing on a given VT input pin, that is, |VIHVT - VILVT|, must be at least 2×VIST.

CML DC ELECTRICAL CHARACTERISTICS
VCC = 2.3V to 3.6V; GND = 0V; TA = –40°C to +85°C
Note 6.
V
OUT(SWING) is defined as the swing on one output of a differential pair, that is |VOH - VOL| on one pin. The swing for common mode noise
immunity purposes is 2 × VOUT(SWING). Actual voltage levels and differential swing will depend on customer termination scheme. Typically, a
400mV swing is available in a 50 environment. Refer to “CML Termination” figures for more details.
