74LVCH16245AEV,151

Overview

The Nexperia 74LVCH16245AEV,151 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 active bus hold on data inputs. It operates within an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Provides bidirectional level translation between mixed 3.3 V and 5 V environments using 5 V tolerant inputs.
• Features active bus hold circuitry on all data inputs to eliminate the need for external pull-up resistors.
• Includes IOFF circuitry that disables outputs to prevent damaging backflow current during partial power-down states.

Applications

• Mixed voltage bus interfaces
• Partial power-down system architectures
• Bidirectional level translation

Procurement Notes

This specific part number is obsolete and no longer in production. Verify availability through secondary market channels or authorized distributors holding remaining stock. Confirm end-of-life status directly with Nexperia before finalizing design-in decisions to ensure long-term supply stability.

Selection Notes

Consider the 74LVCH16245ADGG variant as a current alternative if the TSSOP48 package is acceptable. Evaluate other 16-bit transceivers from the 74LVC family if different pinout configurations or package types are required for the target application.

Part Context

The 74LVCH16245AEV belongs to the 74LVCH16245A series of 16-bit bus transceivers. This series is designed for high-speed bidirectional data transfer with low power consumption. The 'AEV' suffix historically denoted a specific plastic leaded chip carrier package which has been removed from current product offerings.

Replacement Considerations

The 74LVCH16245ADGG is a currently produced equivalent in the same logic family. Verify pin compatibility and package dimensions when substituting this obsolete component.
