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, 2OE, 3OE and 4OE. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. • CMOS low power consumption • MultiByte flow-through standard pin-out architecture • Low inductance multiple VCC and GND pins for minimum noise and ground bounce • Direct interface with TTL levels • Bus hold on data inputs (74ALVCH16244 only) The 74ALVCH16244 has active bus hold circuitry which is provided to hold unused or floating data inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down resistors. • Output drive capability 50 Ω transmission lines at 85 °C • Current drive ±24 mA at 3.0 V • Complies with JEDEC standard no. 8-1 A The 74ALVC16244 has 5 V tolerant inputs. • ESD protection: HBM EIA/JESD22-A114-A exceeds 2000 V MM EIA/JESD22-A115-A exceeds 200 V.

CPD is used to determine the dynamic power dissipation (PD in µW). PD = CPD × VCC2 × fi × N + 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; N = total load switching outputs; Σ(CL × VCC2 × fo) = sum of the outputs. 2.
