9 / 10 page 2003 Dec 08 9 Philips Semiconductors Product specification 16-bit buffer/line driver; 5 V input/output tolerant; 3-state 74LVC16244A; 74LVCH16244A Notes 1. All typical values are measured at VCC = 3.3 V and Tamb =25 °C. 2. For bushold parts, the bushold circuit is switched off when VI >VCC allowing 5.5 V on the input pin. 3. Valid for data inputs of bushold parts (74LVCH16244A) only. For data inputs only, control inputs do not have a bushold circuit. 4. The specified sustaining current at the data inputs holds the input below the specified VI level. 5. The specified overdrive current at the data input forces the data input to the opposite logic input state.
