DM93L28
Dual 8-Bit Shift Register
General Description
The DM93L28 is a high speed serial storage element pro-
viding 16 bits of storage in the form of two 8-bit registers.
The multifunctional capability of this device is provided by
several features: 1) additional gating is provided at the
input to both shift registers so that the input is easily multi-
plexed between two sources; 2) the clock of each register
may be provided separately or together; 3) both the true
and complementary outputs are provided from each 8-bit
register, and both registers may be master cleared from a
common input.
