DM81LS95 3 State Octal Buffer 5V 16A IC DIP-20
The DM81LS95 is a low-power Schottky TTL-based octal buffer integrated circuit designed to handle eight independent data lines with 3-state output capability. Each buffer allows data to pass through while offering a high-impedance state, making it ideal for bus-oriented systems where multiple devices share the same data lines. The enable control pins allow all outputs to be disabled simultaneously, effectively isolating the IC from the bus.
This IC is widely used in digital circuits requiring signal buffering, line driving, and bus interfacing. Its fast propagation delay and low power consumption make it suitable for high-speed logic systems. The 3-state functionality is particularly useful in microprocessor and memory interfacing, where multiple devices must communicate over shared data buses without conflict.
Features:
- Octal buffer with eight independent channels.
- 3-state outputs for bus interfacing.
- Low-power Schottky TTL technology.
- High-speed switching performance.
- Common enable control for all outputs.
- High-impedance output state capability.
- Suitable for digital logic systems.
