The 74LVC16244A; 74LVCH16244A are 16-bit non-inverting buffer/line drivers with 3-state bus compatible outputs. The device can be used as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer. It features four output enable inputs, (1OE to 4OE) each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state.
The document describes the 74LVC16244A and 74LVCH16244A as 16-bit non-inverting buffers or line drivers featuring 5 V tolerant inputs and outputs. These devices support a wide supply voltage range from 1.2 V to 3.6 V and can be configured as four 4-bit, two 8-bit, or one 16-bit buffer.
| Supply voltage range (functional) | 1.2 V to 3.6 V |
|---|---|
| Input/Output tolerance | 5 V tolerant |
| Temperature range (Industrial) | -40 °C to +125 °C |
| ESD protection (HBM) | > 2000 V |
Yes, inputs can be driven from either 3.3 V or 5 V devices.
Up to 5.5 V can be applied to the outputs when the device is disabled.
