General description
The 74LVC16244A; 74LVCH16244A are 16-bit non-inverting buffer/line drivers with 3-state bus
compatible outputs. The device can be used as four 4-bit buffers, two 8-bit buffers or one 16-bit
buffer. It features four output enable inputs, (1OE to 4OE) each controlling four of the 3-state
outputs. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state.
Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be applied to
the outputs. These features allow the use of these devices in mixed 3.3 V and 5 V applications.
The 74LVCH16244A bus hold on data inputs eliminates the need for external pull-up resistors to
hold unused inputs.
Features and benefits
• 5 V tolerant inputs/outputs for interfacing with 5 V logic
• 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 power and ground pins for minimum noise and ground bounce
• Direct interface with TTL levels
• High-impedance when VCC = 0 V
• All data inputs have bus hold. (74LVCH16244A only)
