Übersicht
Description
Key features include:
1. Input and Output: Three binary inputs (A0, A1, A2) select one of the eight outputs (Y0-Y7). The selected output goes low while all others remain high.
2. Enable Inputs: It has three enable inputs (G1, G2A, G2B) that control the operation. The device is active only when G1 is high and both G2A and G2B are low.
3. Speed and Power: Operates at high speeds (up to 6 MHz) with low power requirements, making it suitable for battery-operated devices.
4. Voltage Range: Compatible with standard logic levels (typically 2V to 6V).
Applications include memory address decoding, data routing, and signal demultiplexing in digital circuits.
Features
1. Functionality: It decodes 3 binary inputs into one of eight active low outputs, allowing for efficient signal routing.
2. High-Speed Operation: With a maximum propagation delay of 25 ns at 5 V, it supports fast digital applications.
3. Wide Supply Voltage Range: Operates within a supply voltage range of 2 V to 6 V, compatible with various logic levels.
4. Low Power Consumption: Consumes low static and dynamic power, making it suitable for battery-powered devices.
5. Active Low Outputs: Outputs are active low, providing clear signal differentiation.
6. Enable Inputs: Features two active high enable inputs for enhanced control over the outputs.
7. Pin Configuration: Available in a 16-pin surface-mount package, facilitating compact designs.
8. TTL-Compatible: Compatible with TTL logic levels, ensuring interoperability with existing systems.
These features make the CD74HC238M96 ideal for applications in decoding, memory address decoding, and demultiplexing.
Package
Pinout
- Pins:
- A0, A1, A2 (3 inputs): These are the address inputs used to select which one of the eight outputs will be activated.
- G1 (1 input): Active high enable input.
- G2A, G2B (2 inputs): Active low enable inputs. Both must be low to enable the device.
- Y0 to Y7 (8 outputs): The selected output corresponding to the binary value of A0, A1, and A2 gets activated (low), while all other outputs remain high.
- VCC (1 pin): Power supply pin.
- GND (1 pin): Ground pin.
This device is commonly used in digital circuits to control multiple devices with a minimal number of inputs.
