74LVT16500ADGG,112

Universal Bus Functions Overview

The 74LVT16500ADGG,112 is an 18-bit universal bus transceiver manufactured by Nexperia (formerly NXP). It operates at a supply voltage of 3.3 V with a range of 2.7 V to 3.6 V. The device features non-inverting 3-state outputs and supports bidirectional data flow controlled by OEAB, OEBA, LEAB, LEBA, CPAB, and CPBA inputs. It utilizes negative edge-triggered clock inputs for latching data. The component includes active bus-hold circuitry to maintain valid logic levels on floating inputs without external pull-up resistors. It is housed in a TSSOP56 package.

Universal Bus Functions Feature Summary

• Provides 18-bit bidirectional bus interface capability with non-inverting 3-state buffers.
• Features active bus-hold circuitry to eliminate the need for external pull-up resistors on unused or floating data inputs.
• Supports live insertion and extraction while ensuring power-up reset and power-up 3-state functionality.
• Includes latch-up protection exceeding JESD78 standards and ESD protection meeting MIL STD 883 Method 3015 requirements.

Universal Bus Functions Applications

• High-performance BiCMOS bus interfaces operating at 3.3 V
• Systems requiring TTL input and output switching levels
• Interfaces capable of connecting to systems at 5 V supply

Universal Bus Functions Procurement Notes

Verify that the ordering suffix matches the specific package variant required, as the ADGG designation corresponds to the TSSOP56 plastic thin shrink small outline package. Confirm the manufacturer source, noting that the former NXP Standard Product business was rebranded as Nexperia. Ensure compatibility with the specified temperature range of -40 °C to +85 °C for the intended application environment.

Universal Bus Functions Selection Notes

Select this component when an 18-bit wide bidirectional interface is required within a single package. It is suitable for designs needing simultaneous transparent mode operation and registered data storage via separate latch enable and clock inputs. The inclusion of bus-hold inputs simplifies PCB layout by removing the requirement for discrete pull-up components on unconnected lines.

Universal Bus Functions Part Context

This device belongs to the LVT series of logic integrated circuits, designed for low-voltage 3.3 V applications. It serves as a universal transceiver combining buffer and register functions. The product line transitioned from Philips Semiconductors to NXP and subsequently to Nexperia, maintaining the same functional specifications across these corporate changes.

Universal Bus Functions Replacement Considerations

Check for pin-compatible alternatives within the LVT series such as the 74LVT16245 if registration is not needed. Verify package availability, as the ADGG suffix specifically denotes the TSSOP56 form factor which may have limited stock compared to standard packages.
