1 General 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.
The 74AVC16244 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 dynamic controlled output (DCO) circuitry is implemented to support termination line
drive during transient (see Figure 4).
2 Features and benefits
• Wide supply voltage range from 1.2 V to 3.6 V
• Complies with JEDEC standards:
– JESD8-7 (1.2 V to 1.95 V)
– JESD8-5 (1.8 V to 2.7 V)
– JESD8-1A (2.7 V to 3.6 V)
• 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 VCC and GND pins to minimize noise and ground bounce
• Supports Live Insertion
