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 93L28 is provided by several features: 1) additional gating is provided at the input toboth 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 complementary outputs are provided from each 8-bit register, and both registers may be master cleared from a common input.
