The CD4050BK is a hex non-inverting buffer from Harris Corporation's 4000B CMOS logic family. It operates over a wide 3V to 18V supply range, making it highly versatile for both battery-powered and industrial applications. With six independent buffers, it can drive high-capacitance loads or multiple logic inputs. The device features high output current capability (8mA source, 48mA sink at 18V) and is specified for the full military temperature range of -55°C to 125°C. Housed in a compact 16-lead CFlatPack, it is ideal for space-constrained designs requiring robust signal buffering and level shifting.
- Wide 3V to 18V Supply Range: Compatible with 5V, 12V, and 15V systems, simplifying mixed-voltage designs.
- High Sink Current (48mA): Drives heavy capacitive loads and multiple TTL inputs without performance degradation.
- Full Military Temperature Range (-55°C to 125°C): Suitable for aerospace and harsh-environment applications.
- Non-Inverting Buffer Configuration: Preserves signal polarity, simplifying logic design and debugging.
High-Voltage Level Shifting
With a 3V to 18V supply range, the CD4050BK can interface between 5V microcontrollers and 12V or 15V industrial logic systems, ensuring reliable signal translation without external level shifters.
Driving High-Capacitance Buses
The 48mA sink capability allows the buffer to drive long PCB traces or multiple IC inputs on a bus, reducing signal degradation and improving noise immunity in high-speed digital designs.
CMOS-to-TTL Interfacing
When powered at 5V, the CD4050B can buffer CMOS logic outputs to drive TTL inputs, providing the necessary current and voltage levels for mixed-logic systems.
Oscillator Buffer Isolation
Use the buffer to isolate a crystal oscillator from load variations, maintaining frequency stability by providing a constant drive to the oscillator circuit.
Power Supply Sequencing
In multi-rail systems, the CD4050B can buffer power-good signals, ensuring clean logic transitions to enable or disable converters in the correct order.
Industrial Sensor Conditioning
Buffering analog sensor outputs (in digital mode) or encoder signals in noisy factory environments, the wide voltage range and high noise margin of CMOS ensure robust operation.
