74LVC16245AEV,157

Overview

The Nexperia 74LVC16245AEV,157 is a discontinued 16-bit bus transceiver with 3-state outputs. 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 IOFF circuitry for partial power-down applications and Schmitt-trigger action at all inputs. It operates within an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Provides bidirectional data transmission across two independent 8-bit channels or one 16-bit channel.
• Features IOFF circuitry that disables outputs to prevent damaging backflow current during partial power-down states.
• Includes Schmitt-trigger inputs to ensure tolerance for slower input rise and fall times.

Applications

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

Procurement Notes

This specific part number is no longer in production. Verify availability through authorized distributors as stock may be limited or obsolete. Confirm the exact package type and revision history before design-in, as alternative packages like TSSOP48 are currently active replacements.

Selection Notes

Select this component for designs requiring 16-bit bi-directional level shifting with low power consumption. Ensure the application utilizes the specified 1.2 V to 3.6 V supply range. Consider the 74LVC16245ADGG series if an actively manufactured version with similar electrical characteristics is required.

Part Context

The 74LVC16245AEV belongs to the Nexperia LVC logic family, designed for low-voltage CMOS applications. This specific variant was offered in a distinct package configuration compared to the currently produced ADGG and ADGV versions. It shares functional similarities with other 16-bit transceivers but is distinguished by its specific historical packaging and discontinuation status.

Replacement Considerations

The 74LVC16245ADGG and 74LVCH16245ADGG are actively manufactured equivalents available in TSSOP48 packages. These parts maintain identical logical functionality and electrical specifications suitable for direct replacement in compatible designs.
