Additional Details

The TC74LCXZ240FK features eight independent buffers/line drivers. The direction of data flow is unidirectional. The output enable (OE) input controls the 3-state outputs. When OE is low, the outputs are enabled; when OE is high, the outputs are in the high-impedance state, allowing for bus isolation and memory interface applications. The device's inputs are tolerant to 5.5 V, allowing interface with 5 V logic circuits even when operating at lower supply voltages. The operating temperature range is -40°C to +85°C, making it suitable for a wide range of environments. The device incorporates an advanced noise reduction circuit that minimizes ground bounce and improves overall signal quality. The device is available in VSSOP package. The device supports a wide operating temperature, and it is RoHS compliant. The reduced ground bounce is especially important in applications with multiple devices sharing the same ground plane.
