Product specification
74AVC16244
FEATURES
Wide supply voltage range from 1.2 to 3.6 V
Complies with JEDEC standard no. 8-1A/5/7
CMOS low power consumption
Input/output tolerant up to 3.6 V
Dynamic Controlled Output (DCO) circuit dynamically
changes output impedance, resulting in noise reduction
without speed degradation
Low inductance multiple power and ground pins for
minimum noise and ground bounce
Power off disables 74AVC16244 outputs, permitting live
insertion.
DESCRIPTION
The 74AVC16244 is a 16-bit non-inverting buffer/line
driver with 3-state outputs. This 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 nOE. A HIGH level on input nOE causes the outputs
to assume a high-impedance OFF-state.
This product is designed to have an extremely fast
propagation delay and a minimum amount of power
consumption.
To ensure the high-impedance output state during
power-up or power-down, input nOE should be tied to VCC
through a pull-up resistor (live insertion).
A DCO circuitry is implemented to support termination line
drive during transient (see Figs 1 and 2).

Notes
1. CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi + (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;
(CL × VCC2 × fo) = sum of outputs.
2. The condition is VI = GND to VCC.
