Additional Details

The HD74LVCZ16245ATEL is typically available in a TSSOP package. The direction of data flow is controlled by a direction control (DIR) input. The output enable (OE) input controls whether the outputs are enabled or in a high-impedance state. Further details on switching characteristics and power consumption can be found in the Renesas datasheet for this part.
