FEATURES
PIN CONFIGURATION
• Wide supply voltage range of 1.2V to 3.6V
• Complies with JEDEC standard no. 8-1A
• CMOS low power consumption
• MULTIBYTETM 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 50Ω transmission lines @ 85°C
• Current drive ±24 mA at 3.0 V
DESCRIPTION
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 and 2OE. 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 5V tolerant inputs.

NOTE:
1. CPD is used to determine the dynamic power dissipation (PD in W):
PD = CPD × VCC2 × fi + (CL × VCC2 × fo) where: fi = input frequency in MHz; CL = output load capacitance in pF;
fo = output frequency in MHz; VCC = supply voltage in V; (CL × VCC2 × fo) = sum of the outputs.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
