FEATURES · Wide supply voltage range from 1.2 to 3.6 V · 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) · Output drive capability 50 transmission lines at 85 °C · Current drive ±24 mA at 3.0 V · Complies with JEDEC standard no. 8-1 A · ESD protection: HBM EIA/JESD22-A114-A exceeds 2000 V MM EIA/JESD22-A115-A exceeds 200 V. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf 2.5 ns SYMBOL tPHL/tPLH CI CPD PARAMETERS propagation delay nAn to nYn input capacitance power dissipation capacitance per buffer notes 1 and 2 outputs enabled outputs disabled Notes 1. CPD is used to determine the dynamic power dissipation (PD in µW). PD = CPD × VCC2 × fi × N + (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; (CL × VCC2 × fo) = sum of the outputs. 2. The condition is VI = GND to VCC. CONDITIONS VCC = 2.5 V; CL = 30 pF VCC = 3.3 V; CL = 50 pF DESCRIPTION
74ALVC16244; 74ALVCH16244
The 74ALVC16244; 74ALVCH16244 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, 2OE, 3OE and 4OE. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. 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. The 74ALVC16244 has 5 V tolerant inputs.
