DESCRIPTION The 74ALVC244 is a high-performance, low-power, low-voltage, Si-gate CMOS device and superior to most advanced CMOS compatible TTL families. The 74ALVC244 is an octal non-inverting buffer/line driver with 3-state outputs. 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.

VCC = 2.5 V; CL = 30 pF; RL = 500 2.0 VCC = 2.7 V; CL = 50 pF; RL = 500 2.3 VCC = 3.3 V; CL = 50 pF; RL = 500 2.2 CI CPD Notes 1. CPD is used to determine the dynamic power dissipation (PD in W). PD = CPD x VCC2 x fi x N + (CL x VCC2 x fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in Volts; N = total load switching outputs; (CL x VCC2 x fo) = sum of the outputs. 2. The condition is VI = GND to VCC. input capacitance power dissipation capacitance per buffer VCC = 3.3 V; notes 1 and 2 3.5 20
