MC10E452, MC100E452
5V ECL 5‐Bit Differential
Register
Description
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 D
and the CLK 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 V
CC
.
The fully differential design of the device makes it ideal for very
high frequency applications where a registered data path is necessary.
The V
BB
pin, an internally generated voltage supply, is available to
this device only. For single-ended input conditions, the unused
differential input is connected to V
BB
as a switching reference voltage.
V
BB
may also rebias AC coupled inputs. When used, decouple V
BB
and V
CC
via a 0.01 mF capacitor and limit current sourcing or sinking
to 0.5 mA. When not used, V
BB
should be left open.
The 100 Series contains temperature compensation.
