74LVC162244A 74LVCH162244A 16-bit buffer/line driver 30 series termination resistors 5 V tolerant input/output 3-state Rev. 6 16 December 2011 Product data sheet 1. General description The 74LVC162244A 74LVCH162244A 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 device is designed with 30 series termination resistors in both HIGH and LOW output stages to reduce line noise. 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. The 74LVCH162244A bus hold on data inputs eliminates the need for external pull-up resistors to hold unused inputs. 2. Features and benefits 5 V tolerant inputs/outputs for interfacing with 5 V logic Wide supply voltage range from 1.2 V to 3.6 V CMOS low power consumption Multibyte flow-through standard pin-out architecture Low inductance multiple power and ground pins for minimum noise and ground bounce Direct interface with TTL levels High-impedance when V =0V CC All data inputs have bus hold.
