74LVCH162245ADL:11

Overview

The Nexperia 74LVCH162245ADL:11 is a 16-bit bus transceiver featuring integrated 30 Ω series termination resistors and 5 V tolerant inputs/outputs with 3-state capabilities. It supports a supply voltage range of 1.2 V to 3.6 V and operates within temperatures from -40 °C to +85 °C or +125 °C. The device includes Schmitt-trigger inputs, IOFF circuitry for partial power-down protection, and bus hold functionality on data inputs. It utilizes a standard multibyte flow-through architecture.

Feature Summary

• Integrated 30 Ohm series termination resistors
• Bus hold functionality on all data inputs
• IOFF circuitry for partial power-down mode operation
• Overvoltage tolerant inputs up to 5.5 V

Applications

• Mixed 3.3 V and 5 V environments
• Partial power down applications
• Bi-directional level shifting

Procurement Notes

Verify the package type against the specific suffix in the ordering information table. Confirm that the SSOP-48 variant matches the required thermal derating characteristics. Ensure the selected temperature range aligns with the application environment specifications before finalizing procurement.

Selection Notes

Select this component when 5 V tolerance is required alongside low-voltage operation. The integrated termination resistors simplify PCB layout by reducing external components. Verify that the bus hold feature meets the design requirements for unused input states without additional pull-up resistors.

Part Context

This part belongs to the 74LVCH162245A family, which provides 16-bit bi-directional translation. The 'DL' suffix indicates an SSOP-48 package, though current datasheets list TSSOP48 and TVSOP48 as primary options. The '11' suffix typically denotes tape and reel packaging configuration.

Replacement Considerations

Check for 74LVCH162245ADGG (TSSOP48) or 74LVCH162245ADGV (TVSOP48) if pin-compatible packages are available. Verify functional equivalence regarding bus hold and termination resistor integration.
