74LVC16240A
16-bit buffer/line driver with 5V tolerant inputs/outputs;
inverting; 3-state
Rev. 5 — 25 April 2019
Product data sheet
1. General description
The 74LVC16240A is a 16-bit inverting buffer/line driver with 3-state outputs. The device can be used as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer. The device features four output enables (1OE, 2OE, 3OE and 4OE), each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state.
Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be applied to the outputs. These features allow the use of these devices in mixed 3.3 V and 5 V applications.
This device is fully specified for partial power-down applications using IOFF.
