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.

NOTES: 1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. The input and output voltage ratings may be exceeded if the input and output clamp current ratings are observed.

NOTES: 1. All typical values are at VCC = 3.3V and Tamb = 25C. 2. Valid for data inputs of bus hold parts (LVCH16-A) only. 3. For data inputs only, control inputs do not have a bus hold circuit. 4. The specified sustaining current at the data input holds the input below the specified VI level. 5. The specified overdrive current at the data input forces the data input to the opposite logic input state. 6. For bus hold parts, the bus hold circuit is switched off when Vi exceeds VCC allowing 5.5V on the input terminal.
