74LVT162245BDGG:51

Overview

The 74LVT162245BDGG:51 is a 3.3V LVT 16-bit bidirectional bus transceiver manufactured by Nexperia, formerly NXP Standard Products. It features non-inverting 3-State outputs with integrated 30Ω series termination resistors to minimize line noise and eliminate the need for external components. The device operates within a supply voltage range of 2.7V to 3.6V and supports TTL input/output switching levels. It includes bus-hold data inputs to maintain unused states without external pull-up resistors and provides power-up 3-State functionality for glitch-free operation.

Feature Summary

• Integrated 30Ω series output resistance reduces overshoot and undershoot while eliminating external termination requirements
• Bus-hold data inputs prevent floating states and remove the necessity for external pull-up resistors on unused lines
• Power-up 3-State capability ensures glitch-free bus loading during initialization or power transitions
• Supports live insertion and extraction protocols without causing bus current loading issues

Applications

• Memory address drivers requiring controlled signal integrity
• Clock distribution networks needing minimized line noise
• Bidirectional bus transceivers in high-speed digital systems

Procurement Notes

Verify that the ordering suffix :51 corresponds to the specific tape-and-reel packaging configuration defined in the manufacturer's documentation. Confirm the component originates from Nexperia, as the NXP standard product business was rebranded. Ensure the datasheet revision matches the required specifications for your design implementation.

Selection Notes

Select this component when designing 3.3V logic interfaces that require built-in termination to reduce PCB trace complexity. The integrated 30Ω resistors are suitable for applications where external termination resistors would increase board space or cost. Verify compatibility with 5V tolerant systems if interfacing with legacy logic families.

Part Context

This part belongs to the 74LVT family of high-performance BiCMOS logic devices designed for 3.3V operation. It is functionally equivalent to the 74LVT16245B-1, with the naming change reflecting industry standardization. The device is available in 48-pin TSSOP and SSOP packages, catering to surface-mount assembly requirements in compact electronic designs.

Replacement Considerations

The 74LVT162245B is explicitly identified as the same part as the 74LVT16245B-1. Cross-reference with other 16-bit LVT transceivers only if they match the 30Ω internal termination specification and 3.3V operating voltage constraints.
