93L28

Dual 8-Bit Shift Register

General Description

The 93L28 is a high speed serial storage element providing

16 bits of storage in the form of two 8-bit registers The

multifunctional capability of this device is provided by sever-

al features 1) additional gating is provided at the input to

both shift registers so that the input is easily multiplexed

between two sources 2) the clock of each register may be

provided separately or together 3) both the true and com-

plementary outputs are provided from each 8-bit register

and both registers may be master cleared from a common

input
