| Low-Level Output Voltage (Vol) | 0.4 | V |
The 74ls126 is commonly used as a buffer, meaning it passes a signal through without inverting it, but with increased current drive capability. More importantly, it’s a 3-state buffer. This means each buffer has an enable input. When the enable is active (typically high), the buffer acts as a normal buffer. When the enable is inactive (typically low), the output goes into a high-impedance state, effectively disconnecting it from the circuit. This allows multiple outputs to be connected to a single line, as long as only one output is enabled at a time. Consider this scenario:
- Multiple devices need to send data to a shared data bus.
- Each device uses a 74ls126 as a buffer between its output and the bus.
- Only one device’s 74ls126 enable is active at any given time, allowing it to transmit.
- All other 74ls126 buffers are disabled, preventing signal contention on the bus.
