The SN74HCT125DR is an integrated circuit (IC) component belonging to the 74 series High-Speed CMOS (HCMOS) logic family. This IC acts as a quad bus buffer gate with 3-state outputs, making it suitable for a wide range of digital applications. The following is an overview of the key features and characteristics of the SN74HCT125DR:
1. 4-Bit Buffer Gate: The SN74HCT125DR consists of four independent buffer gates that can each be used to buffer and control signals on a 4-bit bus.
2. High-Speed Operation: As part of the HCMOS logic family, this IC component is capable of operating at high speeds while consuming low power. It is compatible with TTL input and output voltage levels, supporting seamless interfacing between HCMOS and TTL devices.
3. 3-State Outputs: Each buffer gate of the SN74HCT125DR has a 3-state output, meaning it can be actively driven high (logic "1"), actively driven low (logic "0"), or set to a high impedance state (disconnected from the bus). This feature enables easy bus sharing and prevents bus contention issues when multiple devices try to drive the bus simultaneously.
4. Schmitt-Trigger Inputs: The inputs of the SN74HCT125DR are equipped with Schmitt-trigger circuitry, allowing for greater noise immunity and providing hysteresis in the input voltage levels
