The 74HCT126D,652 is an integrated circuit (IC) component belonging to the 74HCT series. It is a quad buffer/line driver with 3-state outputs, designed to work with both TTL and CMOS input voltage levels. Here is an overview and key features of this IC component:
1. Buffer/Line Driver: The 74HCT126D,652 functions as a buffer as well as a line driver, which means it can amplify and transmit digital signals through its output pins. It can be used to drive various loads such as LEDs, relays, digital displays, and other integrated circuits.
2. Quad Configuration: This IC consists of four independent buffer/driver channels, which means it can handle up to four different input signals simultaneously. Each channel has a separate input (A), output (Y), and enable (OE) pin.
3. 3-State Outputs: The 74HCT126D,652 features 3-state outputs, allowing the outputs to be in three different states: High impedance (Z), low logic level (0), and high logic level (1). This feature enables multiple devices to share the same bus, avoiding signal conflicts.
4. Compatibility: The IC is designed to be compatible with both TTL and CMOS input voltage levels. It can accept TTL logic levels of 0.8V to 2.0V and CMOS logic levels of 0 to Vcc
