74LVCH16245AEVY

Overview

The Nexperia 74LVCH16245AEVY is a 16-bit bus transceiver with 3-state outputs, designed for low-voltage operation. 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 Schmitt-trigger action at all inputs and IOFF circuitry for partial power-down applications. Data inputs possess bus hold functionality to eliminate external pull-up resistors. It operates within an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Bus hold on data inputs eliminates the need for external pull-up resistors
• IOFF circuitry prevents damaging backflow current during partial power-down
• Schmitt-trigger action provides tolerance for slower input rise and fall times
• Overvoltage tolerant inputs allow interfacing with 5 V logic in mixed environments

Applications

• Mixed 3.3 V and 5 V system environments
• Partial power-down applications requiring output disabling
• Systems utilizing slow input signal transitions

Procurement Notes

Verify that the specific suffix 'EVY' corresponds to the documented package type and temperature grade in the official Nexperia ordering information. Confirm compatibility with the required JEDEC standards and ESD protection levels specified in the product data sheet before finalizing procurement specifications.

Selection Notes

Select this component when bidirectional level translation between 1.2 V and 3.6 V domains is required alongside 5 V tolerance. Ensure the application benefits from the integrated bus hold feature to simplify design by removing external pull-up components. Verify that the operating temperature range meets the environmental requirements of the target system.

Part Context

This device belongs to the 74LVC(H)16245A family of 16-bit bus transceivers. It utilizes a MULTIBYTE flow-through standard pin-out architecture with low inductance multiple power and ground pins to minimize noise and ground bounce. The technology is CMOS low-power dissipation, compatible with advanced TTL families.

Replacement Considerations

Public confirmed substitute part numbers: 74LVC16245ADGG, 74LVCH16245ADGV.
