74ALVT162245DGG112

Buffers, Drivers, Receivers, Transceivers Overview

The 74ALVT162245DGG112 is a BiCMOS 16-bit bus transceiver with 3-state outputs and integrated 30 Ω series termination resistors. It operates within a supply voltage range of 2.3 V to 3.6 V, supporting both 2.5 V and 3.3 V logic levels. The device features two independent 8-bit sections controlled by separate direction (DIR) and output enable (OE) inputs. Propagation delays range from 0.5 ns to 5.3 ns depending on the voltage and transition direction. It includes bus-hold inputs, IOFF power-down protection, and live insertion capability.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '112' against the manufacturer's official documentation to confirm packaging details. Confirm that the DGG package variant matches the required TSSOP48 footprint. Ensure the component meets the specified -40 °C to +85 °C operating temperature range for the intended application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit wide data paths with integrated termination to reduce board space. It is suitable for applications needing direct interface with TTL levels and overvoltage tolerant inputs up to 5.5 V. Consider the BiCMOS technology for high-speed performance combined with strong output drive capabilities.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74ALVT logic family, designed for advanced low-voltage CMOS applications. It serves as a high-performance alternative to standard bus transceivers by incorporating internal termination. The DGG package identifies it as a thin shrink small outline package with 48 leads.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for 74ALVT162245 variants in different packages such as SSOP48 if pin compatibility allows. Verify functional equivalence regarding propagation delay and output drive strength before substituting.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle unused inputs?

The device features bus-hold data inputs that eliminate the need for external pull-up resistors to hold unused inputs at a defined logic level.

What is the purpose of the internal 30 Ω resistors?

The outputs include series resistance of 30 Ω, which makes external termination resistors unnecessary for impedance matching in many high-speed applications.
