74LVCH16245ADGVJ

Overview

The Nexperia 74LVCH16245ADGV is a 16-bit bus transceiver with direction pin and 3-state outputs. It operates on a supply voltage range of 1.2 V to 3.6 V. The device features overvoltage tolerant inputs up to 5.5 V, Schmitt-trigger action at all inputs, and IOFF circuitry for partial power-down applications. It includes bus hold functionality on data inputs to eliminate external pull-up resistors. The component is housed in a TVSOP48 plastic thin shrink small outline package (SOT480-1) with a body width of 4.4 mm and lead pitch of 0.4 mm.

Feature Summary

• Bus hold circuitry on data inputs eliminates the need for external pull-up resistors to hold unused inputs
• IOFF circuitry provides partial power-down mode operation preventing damaging backflow current
• Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times
• Low inductance multiple power and ground pins designed for minimum noise and ground bounce

Applications

• Mixed 3.3 V and 5 V environments requiring level translation
• Multibyte flow-through standard pin-out architecture systems
• Partial power-down applications utilizing IOFF circuitry

Procurement Notes

Verify the specific ordering suffix ADGV corresponds to the TVSOP48 package (SOT480-1). Confirm that the required temperature range matches the -40 °C to +125 °C specification listed for this variant. Ensure design compatibility with the 1.2 V to 3.6 V supply voltage limits and 5.5 V input tolerance before procurement.

Selection Notes

Select this part when a 16-bit transceiver with integrated bus hold is required. The LVCH series specifically offers bus hold functionality unlike the LVC counterpart. Verify package constraints against the TVSOP48 dimensions. Ensure the application requires the specified 5 V tolerant inputs and low power dissipation characteristics.

Part Context

This component belongs to the 74LVC/LVCH family of logic ICs. It functions as a bidirectional translator between different voltage domains. The device can be configured as two 8-bit transceivers or one 16-bit transceiver using its dual output enable and direction control inputs.

Replacement Considerations

The 74LVC16245ADGV is the non-bus-hold equivalent within the same package. The 74LVCH16245ADGG serves as a pin-compatible alternative but utilizes the TSSOP48 package instead of TVSOP48.
