Common Mode Range
(100KEP) PECL DC ELECTRICAL CHARACTERISTICS(1)
VCC = 5.0V ±10%, VEE = 0V
Note 1. 100KEP circuits are designed to meet the DC specifications shown in the above table after thermal equilibrium has been established. The
circuit is in a test socket or mounted on a printed circuit board and traverse airflow greater than 500lfpm is maintained. Input and output
parameters are at VCC = 5.0V. They vary 1:1 with VCC.
Note 2. VBB reference varies 1:1 with VCC.
Note 3. The VIHCMR range is referenced to the most positive side of the differential input signal. Single-ended input CLK pin operation is limited to VCC
≥
3.0V in PECL mode.

(100KEP) LVECL DC ELECTRICAL CHARACTERISTICS(1)
VEE = –2.37V to –3.8V; VCC = 0V
Note 1. 100KEP circuits are designed to meet the DC specifications shown in the above table after thermal equilibrium has been established. The
circuit is in a test socket or mounted on a printed circuit board and traverse airflow greater than 500lfpm is maintained. Input and output
parameters vary 1:1 with VCC.
Note 2. Single-ended input operation is limited VEE ≤ –3.0V in ECL/LVECL mode. VBB reference varies 1:1 with VCC.
Note 3. VIHCMR (min) varies 1:1 with VEE, VIHCMR (max) varies 1:1 with VCC. The VIHCMR range is referenced to the most positive side of the
differential input signal.
