Overview
The SN74LVT125QPWREP is a 4-channel buffer device produced by Texas Instruments. This component is designed for low-voltage operation, specifically within the range of 2.7 to 3.6 volts, making it suitable for applications requiring TTL-compatible CMOS inputs. The device features independent line drivers with 3-state outputs, which can be enabled or disabled using the output-enable (OE) inputs. Each output is in the high-impedance state when the associated OE input is high. The SN74LVT125QPWREP also includes active bus-hold circuitry to maintain unused or undriven inputs at a valid logic state, and it is fully specified for partial-power-down applications to prevent damaging current backflow.
