CMOS Quad NAND R/S Latch, CD4044BE, Texas Instruments

CD4044BE type is a quad cross-coupled 3-state CMOS NOR latch and the CD4044BE type is a quad cross-coupled 3-state CMOS NAND latch. Each latch has a separate Q output and an individual SET and RESET input. The Q output is controlled by a common ENABLE input. A logic "1" or high on the ENABLE input connects the latch state to the Q output. A logic "0" or low on the ENABLE input disconnects the latch state from the Q output, resulting in an open circuit condition on the Q output. The open circuit feature allows common busing of the output.

Features

• 3-state outputs with common output ENABLE
• Separate SET and RESET inputs for each latch
• NOR and NAND configurations
• Standardized symmetrical output characteristics
• 100% tested for quiescent current at 20 V

Applications

• Holding register in multi-register system
• Four bits of independent storage with output ENABLE
• Strobed register
• General digital logic
