MMC4043

The MMC4043 is a kind of quad cross-coupled 3-state COS/MOS NOR latch. Each latch has a seperate Q output and individual SET and RESET inputs. The Q outputs are controlled by a common ENABLE input. A logic "1" or high on the ENABLE input connects the latch states to the Q outputs. A logic "0" or low on the ENABLE input disconnects the latch states from the Q outputs, resulting in an open circuit condition on the Q outputs. The open circuit feature allows common busing of the outputs. The device is available in 16-lead hermetic dual-in-line ceramic or plastic package.

There are some features of MMC4043 as follows: (1)3-state outputs with common output ENABLE; (2)seperate SET and RESET inputs for each latch; (3)NOR and NAND configurations. The typical applications include holding register in multi-register system, four-bits of independent storage with output enable, strobed register and general digital logic.

What comes next is about the MMC4043 absolute maximum ratings: (1)VDD, supply voltage: -0.5 to 20 V for G and H types and -0.5 to 18 V for E and F types; (2)VI, input voltage: -0.5 to VDD+0.5 V; (3)II, DC input current (any one input): ±10 mA; (4)Ptot, total power dissipation (per package), disspation per output transistor: 200 mW and 100 mW for TA=full package-temperature range; (5)TA, operating temperature: -55 to 125 for G and H types and -40 to 85 for E and F types; (6)Tstg, storage temperature: -65 to 150. Then is about the recommended operating conditions: (1)VDD, supply voltage: 3 to 18 V for G and H types and 3 to 15 V for E and F types; (2)VI, input voltage: 0 to VDD V; (3)TA, operating temperature: -55 to +125 for G and H types and -40 to 85 for E and F types.
