DESCRIPTION
The 74LVCH16541A 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 74LVCH16541A is a 16-bit inverting buffer/line driver with 3-State outputs. The 3-State outputs are controlled by the output enable inputs 1OEn and 2OEn. A HIGH on nOEn causes the outputs to assume a high impedance OFF-state. To ensure the high impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

NOTES: 1. CPD is used to determine the dynamic power dissipation (PD in mW): PD = CPD x VCC2 x fi + S (CL x VCC2 x fo) where: fi = input frequency in MHz; CL = output load capacitance in pF; fo = output frequency in MHz; VCC = supply voltage in V; S (CL x VCC2 x fo) = sum of outputs.

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 performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150C. 3. 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.
