74LVC244A; 74LVCH244A

Octal buffer/line driver; 3-state

[1]

All typical values are measured at VCC = 3.3 V (unless stated otherwise) and Tamb =25 C.

[2]

The bus hold circuit is switched off when VI >VCC allowing 5.5 V on the input terminal.

[3]

Valid for data inputs of bus hold parts only (74LVCH244A). Note that control inputs do not have a bus hold circuit.

[4]

The specified sustaining current at the data input holds the input below the specified VI level.

[5]

The specified overdrive current at the data input forces the data input to the opposite input state.
