1. General description

The 74LVCH16541A is a 16-bit buffer/line driver with 3-state outputs. The 3-state outputs are

controlled by the output enable inputs (1OEn and 2OEn). A HIGH on nOEn 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.

Bus hold on data inputs eliminates the need for external pull-up resistors to hold unused inputs.

2. Features and benefits

• 5 Volt tolerant inputs and 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 outputs when VCC = 0 V

• All data inputs have bus hold

• Complies with JEDEC standard:

• JESD8-7A (1.65 V to 1.95 V)

• JESD8-5A (2.3 V to 2.7 V)

• JESD8-C/JESD36 (2.7 V to 3.6 V)
