General Description

The DM93L28 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 several 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 complementary outputs are provided from each 8-bit register, and both registers may be master cleared from a common input.

Features

■ 2-input multiplexer provided at data input of each register

■ Gated clock input circuitry

■ Both true and complementary outputs provided from last bit of each register

■ Asynchronous master reset common to both registers
