CD4043BE SR tri-state latch / logic chip

The CD4043BE is a quad cross-coupled 3-state CMOS NOR latch. It contains four independent bistable latches, each capable of storing a single bit of information (0 or 1). The outputs can be tri-stated, allowing multiple devices to share a common data line without interference.

Key Features:

• Quad 3-state SR (Set/Reset) latches in a single package
• CMOS technology for low power consumption
• Wide supply voltage range: typically operates from 3V to 15V
• High noise immunity
• Tri-state outputs for bus-oriented applications
• Direct compatibility with TTL and CMOS logic levels

Technical Specifications:

• Logic Family: CMOS
• Number of Latches: 4 (each with Set and Reset inputs)
• Supply Voltage Range: 3V to 15V
• Typical Operating Frequency: Up to 5 MHz at V_DD = 10V
• Power Dissipation: 500 mW (max)
• Input Voltage (V_IH): 0.7 V_DD min, 0.3 V_DD max
• Output Voltage (V_OH): V_DD – 0.05V min

Applications:

• Data storage and control in digital circuits
• State retention and memory elements
• Bus-oriented systems requiring shared data lines
