NXP Semiconductors 74LVC2244A
The 74LVC2244A is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families. These features allow the use of these devices as translators in a mixed 3.3/5 V environment. The 74LVC2244A is an octal non-inverting buffer/line driver with 3-state outputs.| Part No. | 74LVC2244A |

DESCRIPTION
74LVC2244A Inputs can be driven from either 3.3 or 5 V devices. In 3-state operation, outputs can handle 5 V. 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. Schmitt-trigger action at all inputs makes the circuit highly tolerant for slower input rise and fall times. The 74LVC2244A is designed with 30 Ω series termination resistors in both HIGH and LOW output stages to reduce line noise. QUICK REFERENCE DATA Ground = 0 V; Tamb = 25 °C; tr = tf ≤ 2.5 ns. SYMBOL tPHL/tPLH CI CPD Note 1. CPD is used to determine the dynamic power dissipation (PD in µW). PD = CPD × VCC2 × fi + Σ(CL × VCC2 × fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in Volts; Σ(CL × VCC2 × fo) = sum of the outputs.
