DESCRIPTION
The 74LVC(H)16244A is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families. Inputs can be driven from either 3.3V or 5V devices. In 3-State operation, outputs can handle 5V. These features allow the use of these devices in a mixed 3.3V/5V environment. The 74LVC(H)16244A is a 16-bit non-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 3-State outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH on nOE causes the outputs to assume a high impedance OFF-state. The device can be used as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer. The 74LVC(H)16244A is identical to the 74LVC16240A but has non-inverting outputs. The 74LVCH16244A bus hold data inputs eliminates the need for external pull up resistors to hold unused inputs.
