74LVC162245ADGG,11

Overview

The Nexperia 74LVC162245ADGG,11 is a 16-bit bus transceiver housed in a TSSOP48 (SOT362-1) package. It operates within a supply voltage range of 1.2 V to 3.6 V and features 3-state outputs with integrated 30 Ω series termination resistors. The device supports dual 8-bit configurations or a single 16-bit configuration, utilizing separate output enable (nOE) and direction control (DIR) inputs for each byte. Inputs are overvoltage tolerant up to 5.5 V, enabling direct interfacing with 5 V logic in mixed-voltage environments.

Feature Summary

• Integrated 30 Ohm series termination resistors on all data lines
• Bus hold circuitry on data inputs to eliminate external pull-up requirements
• IOFF circuitry providing partial power-down mode protection against backflow current
• Schmitt-trigger action at all inputs for tolerance of slow rise and fall times

Applications

• Mixed 3.3 V and 5 V voltage translation environments
• Partial power-down applications requiring IOFF functionality
• High-speed data buses requiring controlled impedance via integrated termination

Procurement Notes

Verify the specific suffix '11' corresponds to the required tape-and-reel packaging format. Confirm that the TSSOP48 (SOT362-1) package variant matches the PCB footprint design. Ensure the application environment remains within the specified -40 °C to +125 °C temperature range for full operational compliance.

Selection Notes

Select this component when 16-bit bidirectional data transfer is required with integrated signal integrity termination. The LVCH variant specifically includes bus hold features, whereas the LVC variant does not. Verify compatibility with TTL input levels if driving from legacy logic families. Ensure the 5.5 V input tolerance meets the highest voltage present on the bus lines.

Part Context

This part belongs to the 74LVC/LVCH family of high-speed CMOS logic devices manufactured by Nexperia. It is functionally similar to the 74LVCH162245ADGG but distinguished by the absence of bus hold features in the LVC version. The ADGG suffix denotes the plastic thin shrink small outline package with 48 leads and a 6.1 mm body width.

FAQ

Does the 74LVC162245ADGG include bus hold circuitry?

No, the 74LVC162245A variant does not include bus hold circuitry. This feature is exclusive to the 74LVCH162245A variant.

How does the IOFF circuitry function during power-down?

The IOFF circuitry disables the outputs when the device is powered down, preventing potentially damaging backflow current through the device even if input signals are active.
