The SN74HC368ANSR is a hex inverting buffer from Texas Instruments' 74HC family. It features six inverting buffers arranged in two groups of three, each with independent 3-state output enable controls. Operating from 2V to 6V, it supports both 3.3V and 5V logic levels, making it versatile for mixed-voltage systems. Each output can drive up to 7.8mA, suitable for driving LEDs or multiple logic inputs. The 3-state outputs allow for bus sharing and isolation. Housed in a 16-SOIC package, it is ideal for signal inversion, buffering, and level shifting in consumer electronics, industrial controls, and communication systems.
- Wide 2V to 6V Supply Range: Compatible with 3.3V and 5V systems, simplifying design.
- 3-State Outputs: Enables bus sharing and prevents signal contention in multi-device systems.
- High-Speed 74HC Logic: Provides fast propagation delays with low power consumption.
- 7.8mA Output Drive: Sufficient to drive LEDs and multiple logic inputs directly.
- Wide Temperature Range (-40°C to 85°C): Suitable for industrial applications.
Inverting Signal Buffering
The SN74HC368ANSR provides six inverting buffers, useful for signal inversion where a logic high needs to become a logic low, or vice versa, while also regenerating the signal strength.
Bus Driving with 3-State Control
The 3-state outputs allow multiple devices to share a common bus. When the output is disabled, it presents a high-impedance state, preventing data collisions.
Level Shifting Between 3.3V and 5V
With a supply range of 2V to 6V, this buffer can be powered at 3.3V to interface with 3.3V logic while driving 5V loads, or vice versa, simplifying mixed-voltage designs.
Driving LEDs and Small Loads
Each output can source or sink 7.8mA, sufficient to drive LEDs directly with a series resistor, or to drive multiple CMOS inputs.
Clock Inversion and Distribution
In digital systems, an inverted clock signal is often required. This buffer provides both inversion and fan-out, ensuring clean clock distribution to multiple components.
Industrial Control Logic
In industrial controllers, this buffer can be used to invert and buffer control signals, providing the necessary drive strength for long cable runs and noisy environments.
