Product data sheet
1. General 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, 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.
2. Features and benefits
Wide supply voltage range from 1.2 V 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 (2.7 V to 3.6 V)
Bus hold on data inputs (74ALVCH16244 only)
Output drive capability 50 Ω transmission lines at 85 °C
Current drive ±24 mA at 3.0 V
Complies with JEDEC standard no. 8-1A
ESD protection:
HBM JESD22-A114-A exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
