74LVT162245BDGG,11

Overview

The Nexperia 74LVT162245BDGG,11 is a 3.3 V 16-bit bidirectional bus transceiver with integrated 30 Ω termination resistors and 3-state outputs. It operates within a supply voltage range of 2.7 V to 3.6 V and supports overvoltage tolerant inputs up to 5.5 V. The device provides an output capability of +12 mA/-12 mA and features bus-hold data inputs to eliminate external pull-up requirements. It includes IOFF circuitry for partial power-down mode operation and complies with JEDEC standard JESD8C.

Feature Summary

• Integrated 30 Ω series termination resistors in each output path remove the need for external termination components.
• Bus-hold data inputs maintain valid logic levels on unused or floating pins without requiring external pull-up resistors.
• IOFF circuitry automatically disables outputs during power-down to prevent potentially damaging backflow current.

Applications

• High-speed memory bus interfaces
• Parallel data transmission lines
• Mixed-voltage system interconnects

Procurement Notes

Verify the complete part number including the suffix ',11' to ensure correct reel packaging specifications. Confirm that the TSSOP48 (SOT362-1) package variant matches the target PCB footprint. Ensure design compliance with the specified -40 °C to +85 °C operating temperature range and JEDEC standards before finalizing procurement orders.

Selection Notes

Select this component when internal termination is required to minimize board space and simplify layout. The 16-bit width allows configuration as two independent 8-bit channels. Verify that the 2.7 V to 3.6 V supply range aligns with the target system voltage. The BiCMOS technology ensures high speed and robust drive capability suitable for demanding digital interfaces.

Part Context

This device belongs to the 74LVT logic family, designed for low-voltage TTL-compatible applications. It serves as a specialized variant within the 74LVT162245 series by incorporating built-in termination resistors. This integration distinguishes it from standard transceivers that require discrete external components for signal integrity management.

Replacement Considerations

Direct substitutes include other 74LVT162245 variants with identical pinouts but differing termination configurations. Verify functional equivalence regarding the 30 Ω internal resistance and bus-hold capabilities when selecting alternative manufacturers or packages.
