Single-Ended PECL/ECL Feedback Output.
2
D
100k
Single-Ended PECL/ECL Input: The signal input includes an internal 75k
pull-
down resistor. If input is left open, Q output will default to LOW.

Reference
Output
Voltage
Bias Voltage: VCC–1.3V. Used as reference voltage when AC-coupling to the D
input. Max sink/source current 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 QHG and /QHG outputs. Includes internal 75k
pull-up resistor.
Default is HIGH.

VEE
Exposed Pad
Negative
Power
Supply
Negative Power Supply: VEE and exposed pad must be tied to most negative
supply. For PECL/LVPECL connect to ground.

Differential PECL/ECL Output: QHG defaults to LOW and /QHG defaults to HIGH
if D input is left open. See “Output Interface Applications” section for
recommendations on terminations.

Supply
Positive Power Supply: Bypass with 0.1F//0.01F low ESR capacitors as close
to VCC pin as possible.
