If input is left open, Q output will default to LOW. See “Input Interface Applications” section for single-ended inputs. 3 VBB Reference Bias Voltage: V CC–1.3V. Used as reference voltage when AC-coupling to Output Voltage the D input. Max sink/source is ±0.5mA. 4 /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 5 VEE, Negative Negative Power Supply: VEE and exposed pad must be tied to most Exposed Pad Power Supply negative supply. For PECL/LVPECL connect to ground. 6, 7 /QHG, QHG 100k Differential PECL/ECL Output: Defaults to LOW if D inputs left open. ECL Output See “Output Interface Applications” section for recommendations on terminations. 8 VCC Positive Positive Power Supply: Bypass with 0.1 µF//0.01µF low ESR capacitors.
