74LVC245A; 74LVCH245A

Octal bus transceiver; 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]

For I/O ports the parameter IOZ includes the input leakage current.

[4]

Valid for data inputs of bus hold parts only (74LVCH245A). Note that control inputs do not have a bus hold circuit.

[5]

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

[6]

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