74LVCH162245ADL,11

Overview

The Nexperia 74LVCH162245ADL,11 is a 16-bit bus transceiver featuring integrated 30 Ω series termination resistors and 3-state outputs. It supports a supply voltage range of 1.2 V to 3.6 V with inputs tolerant to 5.5 V. The device includes Schmitt-trigger inputs for noise immunity and IOFF circuitry for partial power-down protection. Data inputs feature bus hold functionality to eliminate external pull-up requirements. It operates within an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Integrated 30 Ω series termination resistors for signal integrity
• Bus hold on all data inputs to maintain logic states without external components
• IOFF circuitry prevents backflow current during partial power-down
• Schmitt-trigger action ensures tolerance to slow input rise and fall times

Applications

• Mixed 3.3 V and 5 V environment translation
• High-speed data bus buffering
• Partial power-down system configurations

Procurement Notes

Verify the specific ordering suffix matches the required package type. Confirm that the ADL designation corresponds to the SSOP48 variant, as revision history indicates this package was removed in later datasheet versions. Ensure compatibility with the intended operating temperature range and verify current production status directly with the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring integrated termination to reduce external component count. The LVCH family offers low power consumption suitable for battery-operated devices. Verify that the 5 V tolerant inputs align with the driving source voltages. Consider the SSOP48 package dimensions against available PCB real estate constraints.

Part Context

This part belongs to the 74LVC/LVCH 162245A family of 16-bit transceivers. While the datasheet primarily lists TSSOP48 and TVSOP48 packages in current ordering tables, the ADL suffix historically denotes the SSOP48 package. Designers should consult the latest official documentation to confirm if this specific package variant remains in active production or has been superseded by other form factors.

Replacement Considerations

Check for 74LVC162245ADGG or 74LVCH162245ADGG equivalents if the SSOP48 package is unavailable. Verify pinout compatibility and electrical specifications match exactly before substitution.
