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