74LVC16245ADGG,118

Overview

The Nexperia 74LVC16245ADGG,118 is a 16-bit bus transceiver with 3-state outputs housed in a 48-lead TSSOP package. It supports a supply voltage range of 1.2 V to 3.6 V and features overvoltage tolerant inputs up to 5.5 V. The device includes two output enables and two direction control inputs, allowing operation as one 16-bit or two 8-bit transceivers. It incorporates Schmitt-trigger inputs for noise immunity and IOFF circuitry for partial power-down protection.

Feature Summary

• Provides bidirectional level translation between mixed 3.3 V and 5 V logic environments
• Includes IOFF circuitry to prevent damaging backflow current during partial power-down states
• Features Schmitt-trigger action at all inputs to tolerate slower rise and fall times

Applications

• Mixed voltage system interconnects
• Partial power-down mode applications
• Bidirectional data bus buffering

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the component meets the necessary environmental specifications for the intended operating temperature range. Ensure compatibility with the target PCB footprint dimensions before finalizing procurement orders.

Selection Notes

Select this component when interfacing systems with different supply voltages requiring robust noise immunity. The inclusion of IOFF circuitry makes it suitable for designs needing safe partial power-down capabilities. Verify that the 48-TSSOP package fits within the available board space constraints.

Part Context

This part belongs to the 74LVC16245A family of 16-bit bus transceivers manufactured by Nexperia. It shares functional characteristics with other variants in the series but is distinguished by its specific TSSOP48 packaging configuration and associated thermal properties defined in the product data sheet.

Replacement Considerations

The 74LVCH16245ADGG,118 serves as a direct functional substitute within the same family, offering identical pinout and electrical characteristics while including active bus hold on data inputs.
