Single-Ended PECL/ECL Input: The signal input includes an internal 75k

Ω

pull-down ECL Input resistor. If input is left open, Q output will default to

LOW. See “Input Interface Applications” section for single-ended inputs.

/EN

Enable Input

/EN Input which is synchronized with data input (D) signal in a way that

provides glitchless gating of Q

HG and /QHG outputs. Includes internal 75kΩ

pull-down resistor. Default is LOW
