DESCRIPTION
The SY10/100E143 are high-speed 9-bit hold registers
designed for use in new, high-performance ECL systems.
The E143 can hold current data or load new data. The nine
inputs, D0-D8, accept parallel input data.
The SEL (Select) control pin serves to determine the
mode of operation; either HOLD or LOAD. The input data
has to meet the set-up time before being clocked into the
nine input registers on the rising edge of CLK1 or CLK2.
The MR (Master Reset) control signal asynchronously
resets all nine registers to a logic LOW when a logic HIGH
is applied to MR.
The E143 is designed for applications requiring high-
speed registers, pipeline registers, synchronous operation,
and is also suitable for byte-wide parity.
