FEATURES
DESCRIPTION
• Wide supply voltage range from 1.2 to 3.6 V
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.
• 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.

Notes
1. 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. The condition is VI = GND to VCC.
