SY10/100EP451L
3.3V ECL 6-Bit Differential Register
with Master Reset
General Description
The SY10/100EP451L is a 6-bit fully differential register
with common clock and single-ended Master Reset (MR).
It is ideal for very high frequency applications where a
registered data path is necessary.
All inputs have an internal 75kΩ pull-down resistor.
Differential inputs have an override clamp. Unused
differential register inputs can be left open and will default
LOW. When the differential inputs are forced to a value
smaller than VEE +1.2V, the clamp will override and force
the output to a default state.
The positive transition of CLK (pin 4) will latch the
registers. Master Reset (MR) HIGH will asynchronously
reset all registers forcing Q outputs to go LOW.
Datasheets and support documentation can be found on
Micrel’s web site at: www.micrel.com.

Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. θJA and θJC values are determined for a 4-layer board in still-air unless otherwise stated.
4. The device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit board with maintained transverse
airflow greater than 500lfpm. Electrical parameters are guaranteed only over the declared operating temperature range. Functional operation of the device exceeding
these conditions is not implied. Device specifications limit values are applied individually under normal operating conditions and not valid simultaneously.
5. Input and output parameters vary 1:1 with VCC.
6. All loading with 50Ω to VCC–2.0V.
7. 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.
