Additional Details

The 74HCT238BQ,115 operates within a supply voltage range of 4.5V to 5.5V. It is available in a DHVQFN16 (very thin quad flatpack no leads) package. The device features three binary select inputs (A0, A1, A2) and three enable inputs (E1, E2, E3). When all enable inputs are active (LOW), the device decodes the binary address present on the select inputs and activates the corresponding output. Unselected outputs are HIGH. The device's inputs include clamp diodes, enabling the use of current limiting resistors to interface inputs to voltages in excess of VCC.
