74LVC162244A LVCH162244A 16-bit buffer/line driver 30 series termination resistors 5 V tolerant input/output 3-state Rev. 8 23 September 2021 Product data sheet 1. General description The 74LVC162244A 74LVCH162244A is a 16-bit buffer/line driver with 30 termination resistors and 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. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V environments. Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times. This device is fully specified for partial power down applications using I . The I circuitry OFF OFF disables the output, preventing the potentially damaging backflow current through the device when it is powered down. The 74LVCH162244A bus hold on data inputs eliminates the need for external pull-up resistors to hold unused inputs. 2. Features and benefits Overvoltage tolerant inputs to 5.5 V Wide supply voltage range from 1.2 V to 3.6 V CMOS low power dissipation 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 I circuitry provides partial Power-down mode operation OFF All data inputs have bus hold.
