MC10E452: 5.0 V ECL 5-Bit Differential Register
Description: The MC10E/100E452 is a 5-bit differential register...
The MC10E/100E452 is a 5-bit differential register with differential data (inputs and outputs) and clock. The registers are triggered by a positive transition of the positive clock (CLK) input. A high on the Master Reset (MR) asynchronously resets all registers so that the Q outputs go LOW.
The differential input structures are clamped so that the inputs of unused registers can be left open without upsetting the bias network of the device. The clamping action will assert the Dbar and the CLKbar sides of the inputs. Because of the edge triggered flip-flop nature of the device simultaneously opening both the clock and data inputs will result in an output which reaches an unidentified but valid state. Note that the input clamps only operate when both inputs fall to 2.5 V below VCC .
The fully differential design of the device makes it ideal for very high frequency applications where a registered data path is necessary.
The VBB pin, an internally generated voltage supply, is available to this device only. For single-ended input conditions, the unused differential input is connected to VBB as a switching reference. VBB may also rebias AC coupled inputs. When used, decouple VBB and VCC via a 0.01 uF capacitor and limit current sourcing or sinking to 0.5 mA. When not used, VBB should be left open.
The 100 Series contains temperature compensation.
